What is the value of x?

12x+34=9

B. 16 1/2

Step-by-step explanation:

1/2x+3/4=9

multiply both sides by 4

4(1/2x+3/4)=9x4

2x+3=36

2x=36-3

2x=33

x=33/2

x=16 1/2

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
