Answer:

- 77

Step-by-step explanation:

To evaluate, substitute x = 4 into g(x) then substitute the value obtained into f(x).

g(4) = 4² + 3 = 16 + 3 = 19

f(19) = (- 4 × 19) - 1 = - 76 - 1 = - 77

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

5x - y = 8 ( subtract 5x from both sides )

- y = - 5x + 8 ( multiply through by - 1 )

y = 5x - 8 ← in slope- intercept form

with slope m = 5 and y- intercept c = - 8
