Evaluate Function Expressions

5•f(1)+5•g(9)=

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

where's the diagram?

step-by-step explanation:

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
