Step-by-step explanation:

Substitute x = - 5 into f(x), that is

f(- 5) = 5(- 5) + 40 = - 25 + 40 = 15

Tell which equation you would choose to solve for one of the variables when solving the system by substitution. 2x+3y=5 4x-y=3

PtichkaEL [24]

i would solve 4x-y =3 for y because the coefficient for y is 1

subtract 4x from each side

-y = -4x+3

divide by -1

y = 4x-3
