Find the value of f(5) for the function.
f(x)=−6(x+1)

f(5) = -36

Step-by-step explanation:

Plug in 5 as x:

f(x) = −6(x + 1)

f(5) = -6(5 + 1)

Simplify:

f(5) = -6(6)

f(5) = -36

So, f(5) = -36

.25

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
