Question & Answer
Does (7, 0) make the equation y = 2x² – 3x – -7 true?
1 Answer
Verified archiveTo check if the point (7, 0) makes the equation ( y = 2x^2 – 3x – 7 ) true, we can substitute ( x = 7 ) into the equation and see if we get ( y = 0 ).
1. Substitute ( x = 7 ):
[
y = 2(7)^2 – 3(7) – 7
]
2. Calculate ( y ):
[
y = 2(49) – 21 – 7
]
[
y = 98 – 21 – 7
]
[
y = 70
]
3. Compare the calculated ( y ) with 0:
Since ( y = 70 ) does not equal 0, the point (7, 0) does not make the equation true.
Therefore, the answer is no.
