Answer:
5•f(1) + 5•g(9) = -55
Step-by-step explanation:
Given two functional expressions represented by the graph, to find the value of this equation, just evaluate where y is given the input or x value.
5•f(1) + 5•g(9) is 5 times the y value of function f at 1x plus 5 times the y value of function f at 9x.
According to the graph, the y value of the f function at 1x is -5, and the y value of function g at 9x is -6.
Therefore 5•f(1) + 5•g(9) = 5•-5 + 5•-6 = -25 + -30 = -55
