Answer:

f(-1) = -19

Step-by-step explanation:

Using the equation

(f(x) = -11 + 8x) we use f(-1) into it.

f(-1) = -11 + 8(-1)

f(-1) = -11 -8

f(-1) = -19

Answer:

\large \boxed{\sf \ \ x=0, \ \ y=-5 \ \ }

Step-by-step explanation:

Hello, please consider the following.

We have two equations:

(1) -2x - 4y = 20

(2) -3x + 5y = -25

5*(1)+4*(2) gives

   -10x - 20y -12x + 20y = 100 - 100 = 0

   -22x = 0

   x = 0

I replace in (1)

   -4y = 20

   y = -20/4 = -5

There is one solution x = 0, y = -5

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
