Ответ:
x = -2
Step-by-step explanation:
Step 1: Substitute h(x) for -9
-9 = 4x - 1
Step 2: Solve for x
-8 = 4x
x = -2
Ответ:
x = -2.
Step-by-step explanation:
h(x) = 4x - 1, h(x) = -9.
-9 = 4x - 1
4x - 1 = -9
4x = -8
x = -2
Check your work!
4 * (-2) - 1
= -8 - 1
= -9
Since it works out, x = -2.
Hope this helps!
