you have to divide each side by -3 You also have to flip the sign also.

OpenStudy (anonymous):

\[t \epsilon (-\infty,-13]\]

OpenStudy (anonymous):

A. t ≥ 13 B. t ≥ –13 C. t ≤ –13 D. t ≤ 13

OpenStudy (anonymous):

t<=-13

OpenStudy (anonymous):

Your answer will be C Does that make sense?

OpenStudy (anonymous):

thanks so much @KirbyLegs yeah it makes sense :)

Can you help me with this last one? : Solve. –7 ≥ 13 – 5x A. x ≥ –4 B. x ≤ –4 C. x ≥ 4 D. x ≤ 4

OpenStudy (anonymous):

Of course -7>13 - 5x Bring the constants together -7 -13 > -5x

OpenStudy (anonymous):

-20 > -5x 4< x

OpenStudy (anonymous):

D is correct answer. Does that make sense?

OpenStudy (anonymous):

Yep :)

OpenStudy (anonymous):
