Question

Find the value of x so that the function has the given value.

m(2) = 4x + 15; m(t) = 7
A. x = -5
B. x = -4
C. x = -3
D. x = -2

Answer 1

The value of x in the equation m(2) = 4x + 15 is -4.

Step-by-step explanation:

To find the value of x in the equation m(2) = 4x + 15, we need to substitute the given value of m(t) = 7 and solve for x. We have: 4(2) + 15 = 7. Simplifying this equation, we get: 8 + 15 = 7. Therefore, the correct value of x is -4 (option B).
