Which inequality is equivalent to -4t ≥ 28?
t ≥ -7
t ≤ -7
t ≥ 7
t ≤ 7
To solve the inequality (-4t geq 28), we first divide both sides by (-4). Remember that when we divide or multiply both sides of an inequality by a negative number, we must reverse the inequality sign.
So, dividing both sides by (-4):
[
t leq frac{28}{-4}
]
This simplifies to:
[
t leq -7
]
So, the correct answer is: t ≤ -7.
This means that (t) can be any value less than or equal to (-7). If you need more detailed assistance, feel free to check the extended services page!
