If you’re good at algebra could somebody help me please?

a). f(0) = 7

b). f() = 6

c). f(-5) = 22

d). x = 9

Step-by-step explanation:

The given function is f(x) = -3x + 7

a). For x = 0

   f(0) = -3(0) + 7

         = 0 + 7

         = 7

b). For x =

    f() =

          = -1 + 7

          = 6

c). For x = (-5)

   f(-5) = -3(-5) + 7

          = 15 + 7

          = 22

d). For f(x) = (-20)

    -20 = -3x + 7

     3x = 20 + 7

     3x = 27

       x = 9            

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
