C is the correct answer. The equation for f(x) is f(x)=1.8x-10 and the equation for g(x) is g(x)=-4 . Since we're trying to find the input value for x where f(x)=g(x) make the 2 equations equal to each other and you'll get your answer.

Step-by-step explanation:
just add them together :)
haha lol I was looking for the answer too, but I solved it! Here it is:
Answer:
The slope of line s is b/a. Rotate line s 90° clockwise about the origin to get line t. The labeled points on line s map to (0, a) and (b, 0) on line t. The slope of line t is -a/b. The slopes of the lines are opposite reciprocals because the product of the slopes is -1.
4/5+3/5 = 7/5 = 1.4
3.5X5 = 17.5
1.4 + 17.5 = 18.9 = 18 9/10
