To determine which graph best shows Andrea and Damian’s collection plan, let’s analyze their goals:
– Damian starts with 5 items and collects 3 items per day. His daily collection can be represented by the equation ( y = 3x + 5 ) where ( y ) is the total number of items collected and ( x ) is the number of days.
– Andrea collects 4 items per day and starts from 0, represented by the equation ( y = 4x ).
Now, since we need to show both lines on one graph, the correct set of equations based on their collection plans is:
– ( y = 3x + 5 ) for Damian
– ( y = 4x ) for Andrea
So, the correct answer is:
y = 3X + 5 and y = 4x.
This combination highlights both collection plans accurately over time.

The correct answer is B) They are more likely than someone without a risk factor to perpetrate or experience bullying.
Explanation: Having a risk factor for bullying means that an individual has characteristics or circumstances that increase their likelihood of being involved in bullying situations, either as a perpetrator or as a victim. This does not guarantee that the individual will experience or engage in bullying, but it suggests a higher probability compared to those without such risk factors.

To find the surface area of a figure composed of 4 identical cubes, we first need to find the surface area of one cube. The surface area (S) of a cube with edge length (a) is given by the formula:
[ S = 6a^2 ]
Since we have 4 identical cubes, if they are arranged separately, the total surface area would be:
[ Total Surface Area = 4 times 6a^2 = 24a^2 ]
However, if the cubes are joined together in a way that some surfaces are hidden (i.e., touching each other), we need to account for those hidden surfaces, which reduces the total surface area.
If you provide the arrangement or dimensions of the cubes, we can adjust the calculations accordingly. Without this specific information about how the cubes are positioned, I can’t give an exact surface area.

To solve the problem, let’s define the two numbers as ( x ) and ( y ). Based on the information given, we can create the following system of equations:
1. ( x + y = 9 ) (their sum)
2. ( x cdot y = 20 ) (their product)
Now, let’s fill in the table:
– First Number: ( x )
– Second Number: ( y )
– Total: ( 9 )
– Added: ( 9 )
– Multiplied: ( 20 )
To find the specific values of ( x ) and ( y ), we can solve this system. From the first equation, we can express ( y ) in terms of ( x ):
[ y = 9 – x ]
Now, substitute ( y ) in the second equation:
[ x(9 – x) = 20 ]
Expanding this gives:
[ 9x – x^2 = 20 ]
Rearranging it:
[ x^2 – 9x + 20 = 0 ]
Now, we can factor the quadratic:
[ (x – 5)(x – 4) = 0 ]
This gives us the solutions:
[ x = 5 quad text{or} quad x = 4 ]
Thus, the two numbers are ( 5 ) and ( 4

To find the surface area of the new shape formed by joining four identical cubes, we first need to determine the dimensions of one cube.
Assuming each cube has a side length of ( s ), the surface area of one cube is ( 6s^2 ). When four cubes are joined together, certain faces are hidden, which reduces the overall surface area.
For example, if we arrange the cubes in a line (1×4), two faces will be hidden, resulting in fewer exposed faces. The formula to calculate the new surface area depends on how the cubes are arranged.
Without specific dimensions or an arrangement, let’s assume the most efficient arrangement, such as a 2×2 formation (which reveals 10 faces):
1. Surface area of 4 cubes alone = ( 4 times 6s^2 = 24s^2 )
2. Subtract the hidden faces = ( 24s^2 – 4s^2 = 20s^2 )
However, since we don’t have the side length ( s ), we can’t calculate a specific surface area.
But from the given options, if we assume ( s = 15ft ):
1. Surface area of 1 cube = ( 6 times 15^2 = 1350 ft² )
See less2. Total for 4 cubes = ( 4 times 1350 = 5400 ft² )

To determine if Lupé can make a profit by selling the bracelets, let’s analyze the information provided.
1. Income Per Bracelet: Lupe earns $0.50 per bracelet.
2. Cost Per Bracelet: It costs Lupe $0.50 to create each bracelet.
3. Break-even Point: If Lupe sells 25 bracelets:
– Income from selling 25 bracelets = 25 bracelets × $0.50 = $12.50
– Cost to create 25 bracelets = 25 bracelets × $0.50 = $12.50
– Profit = Income – Cost = $12.50 – $12.50 = $0 (break-even)
4. Less Than 30 Bracelets for Profit: If she sells less than 30 bracelets, based on the given that it costs her $0.50 per bracelet to produce the same amount she sells, she cannot make a profit from selling 25 bracelets.
So, it’s not possible for Lupe to make a profit selling 25 bracelets because she breaks even. It’s indicated that she must sell more than 30 bracelets to make an actual profit given her costs and earnings.
In conclusion, Lupe will not make a profit selling 25 bracelets, as she only breaks even at that point. If she needs clarification or further assistance, they should check the extended services page for more in-depth help.

To find when the second truck passes the first truck, we can compare their distances as functions of time.
1. Distance for Truck 1: Since Truck 1 is 50 miles ahead and travels at 60 miles per hour, its distance after ( t ) hours is:
[
D_1 = 50 + 60t
]
2. Distance for Truck 2: Truck 2 travels at 70 miles per hour, so its distance after ( t ) hours is:
[
D_2 = 70t
]
3. Setting the distances equal: To find when Truck 2 passes Truck 1, we set their distances equal:
[
50 + 60t = 70t
]
Simplifying this:
[
50 = 70t – 60t

To determine the number of solutions a given equation or system of equations has, we can analyze it as follows:
1. No Solutions: This occurs when the equations contradict each other, meaning there is no set of values for the variables that can satisfy all equations simultaneously. An example is the equations (x + 2 = 5) and (x + 2 = 6); these create parallel lines that never intersect.
2. One Solution: This occurs when there is exactly one set of values for the variables that satisfies the equations. In a system of two linear equations, this happens when the lines intersect at a single point. For example, the equations (x + y = 2) and (x – y = 0) will intersect at one unique point.
3. Infinitely Many Solutions: This is the case when the equations represent the same line, meaning any solution for one equation is also a solution for the other. For example, the equations (2x + 4y = 8) and (x + 2y = 4) are equivalent, leading to infinitely many solutions.

However, it is impossible for two lines to intersect at two different points; if they did, they would not actually be two distinct lines.

To determine which rule can be used to find the value of ( g ), we need to consider the context of the problem, specifically if it involves a triangle.
– Law of Cosines: This rule is used when you have two sides and the included angle or all three sides of a triangle.
– Law of Sines: This rule is applicable when you have two angles and a side or two sides and a non-included angle.
– Pythagorean Theorem: This is used for right triangles when you have two sides and want to find the third side.
If the value of ( g ) corresponds to a side or angle in a triangle, you would choose based on the information given. If there’s not enough information, the last option would apply.
Without the specific context, it’s challenging to determine definitively. If you can provide more details about the triangle or the values given, I would be glad to assist further! Please feel free to ask if there’s anything specific about this question.

To find the value of t in a triangle, you can generally use either the Law of Sines or the Law of Cosines, depending on the information you have.
1. Law of Sines: This can be used when you know two angles and one side (AAS or ASA) or two sides and a non-included angle (SSA). It states that the ratios of the sides of a triangle to the sines of their opposite angles are equal.
2. Law of Cosines: This is applicable when you know two sides and the included angle (SAS) or all three sides (SSS). It relates the lengths of the sides of a triangle to the cosine of one of its angles.
3. Pythagorean Theorem: This is specifically used for right triangles and relates the lengths of the sides as (a^2 + b^2 = c^2).
If the context provides specific angles or sides, you can determine which law to apply.

See lessGloria wants to find the length of segment N P. Which set of steps will give her the correct length? 1. Find segment M P using the equation cos 60° = M P / 31. 2. Find segment N P using the Pythagorean theorem, M N² = M P² + N P². 1. Add 25° + 60°, and then subtract the result from 180° to find m∠M. 2. Find segment M P using the equation tan M = N P / M P. 1. Find segment M P using the equation tan 25° = M P / 31. 2. Find segment N P by subtracting segment L P from segment L N.
To solve for the length of segment NP, the best set of steps is the following: 1. Find segment MP using the equation tan 25° = MP / 31.This step allows Gloria to find the length of segment MP based on the angle given and the length of the adjacent segment (which in this case is 31). 2.

To solve for the length of segment NP, the best set of steps is the following:
1. Find segment MP using the equation tan 25° = MP / 31.
This step allows Gloria to find the length of segment MP based on the angle given and the length of the adjacent segment (which in this case is 31).
2. Find segment NP using the Pythagorean theorem, MN² = MP² + NP².
Once MP is known, she can use the Pythagorean theorem to find NP since MN is a right triangle.
### Explanation:
The first step uses tangent to relate the opposite and adjacent sides of a right triangle, resulting in the length of segment MP. The second step then applies the Pythagorean theorem, which is appropriate for any right triangle, to solve for NP. This method is systematic and uses the principles of trigonometry effectively.

See lessYou and your friend each start a car-washing service. You spend $25 on supplies and charge $10 per car. Your friend spends $55 on supplies and charges $13 per car. How many cars do you have to wash to earn the same amount of money as your friend?
To find out how many cars you need to wash to earn the same amount as your friend, we need to set your earnings equal to your friend's earnings. 1. Your earnings: ( y = 10x - 25 ) 2. Friend's earnings: ( y = 13x - 55 )Set them equal to each other:[ 10x - 25 = 13x - 55 ]Now, let's solve for ( x ): 1.Read more
To find out how many cars you need to wash to earn the same amount as your friend, we need to set your earnings equal to your friend’s earnings.
1. Your earnings: ( y = 10x – 25 )
2. Friend’s earnings: ( y = 13x – 55 )
Set them equal to each other:
[ 10x – 25 = 13x – 55 ]
Now, let’s solve for ( x ):
1. Subtract ( 10x ) from both sides:
[ -25 = 3x – 55 ]
2. Add 55 to both sides:
[ 30 = 3x ]
3. Divide both sides by 3:
[ x = 10 ]
So, you need to wash 10 cars to earn the same amount of money as your friend. Keep up the great work! If you need further assistance, feel free to check the extended services page.

To determine which graph represents the situation, let’s analyze the scenario:
1. The first truck starts 50 miles ahead and travels at 60 mph.
2. The second truck starts from a point 50 miles behind and travels at 70 mph.
To find out when the second truck will catch up with the first truck, we can set up an equation. Let ( t ) be the time in hours:
– Distance traveled by the first truck: ( 60t + 50 ) (starts 50 miles ahead)
– Distance traveled by the second truck: ( 70t )
We want to find ( t ) when both have traveled the same distance:
[ 70t = 60t + 50 ]
Now, subtract ( 60t ) from both sides:
[ 10t = 50 ]
Now, divide both sides by 10:
[ t = 5 ]
So, it will take the second truck 5 hours to catch up with the first truck.
In terms of a graph, you would want to look for a graph where the line representing the distance of the second truck crosses the line representing the distance of the first truck at the 5-hour mark.
If you have options for graphs, the correct graph would show the point of intersection at ( t = 5 ) hours.
