Determine the solution to f(x) = g(x) using the following system of equations: (5 points) f(x) = 3x + 12 g(x) = −9.5x − 13 select one: a. x = −2 b. x = −3 c. x = 4 d. x = 5

a. x = −2

Step-by-step explanation:

f(x) = g(x)

Substitute the functions in

3x+12 = -9.5x -13

Add 9.5x to each side

3x+9.5x+12 = -9.5x+9.5x -13

12.5x +12 = -13

Subtract 12 from each side

12.5x+12-12 = -13-12

12.5x = -25

Divide by 12.5

12.5x/12.5 = -25/12.5

x = -2

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
