Solve 2x - 9 = 15)

1) 3

2) 4

3) 12

4) 48

9514 1404 393

  3)  12

Step-by-step explanation:

Add 9 to both sides of the equation.

  2x -9 +9 = 15 +9

  2x = 24

Divide both sides of the equation by 2.

  2x/2 = 24/2

  x = 12

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
