I think you are asking if -8x ≥ 40, find x. What we do here is we divide negative 8 by both sides. This gives us x ≥ 5. BUT, we have to be careful!!!! When we divide an inequality on both sides by a negative number, we have to switch the sign. Thus, our answer is x ≤ 5.
Answer:
A
Step-by-step explanation:
on the left of the equation, (6^4)^-5 = 6^-20
the right side you add the exponents so it would be (-7-3) =-10
so it would be 6^-10, which is greater than 6^-20
