C) x ≦ −9
D) x ≦ −2

Help please!

Step-by-step explanation:

When solving absolute value equations, we have to remember a simple rule:

means

a < b

and

a < -b

Now, onto our equation:

We can write:

1.

and

2.

Solving #1,

Solving #2,

Note: remember to change inequality signs when dealing with negatives

So, the solution is all numbers between -9 and 9 inclusive. Or in other words:

ANswer choices are wrong.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
