C because the slope of f(x) is -2, and the slope of g(x) is -7

Answer: x = 54

Explanation:

180 - 14 = 166

3x + 4 = 166

3x = 162

x = 162/3 = 54

Answer: y=5 x=1

Step-by-step explanation: to know the real zero you

First choose from the equation if x is equal to 1 and input it into the equation

Y= -3(1)+8

Y=-3+8

Y=5

Therefore

If

Y is 5 apply it to the equation

5=-3(1)+8

5=-3+8

5=5

5-5=0
