Answer: -7

Step-by-step explanation:

First, lets use the functions to find the answer to f(-8) and g(4)

f(-8) is the same as asking for the value of y when x is -8

Therefore, f(-8) = -5 (according to the graph)

Using the same rule, g(4) would be the value of y when x = 4 which,

according to the graph, g(4) = 3

Plug these values back into the original equation to get:

$-1*f(-8)-4*g(4)=?\\=-1*-5-4*3\\$

using the order of operations, we will multiply the values first

$(-1*-5)+(-4*3)\\=5+(-12)\\=5-12\\=-7$

<h2>Therefore, our final answer is -7</h2>
