B.) y = -x/2 - 1 is the right answer
hope this helped!

I solved it and attached it in the file!
Answer:
x =9/4
Step-by-step explanation:
log3(4x) = 2
Raise each side to the base of 3
3^ log3(4x) = 3^2
We know that 3log3 is 1
4x = 9
Divide each side by 4
4x/4 = 9/4
x = 9/4
Answer:
so we get as,
let, y = 2 - 9i
so the absolute value is |y|
so we get as,
|y| =
2-9i
so the absolute value is |y|
|y|=√
2 to the 2nd power plus 9 to the second power
so we get as,
|y|=
√81+4=√85
so the value is √85
