Isolate the y

add 7 to both sides

y - 7  = 21

y - 7 (+7) = 21 (+7)

y = 21 + 7 

y = 28

28 is your answer

hope this helps

What are the zeros of the polynomial function f(x)=x(x-4)(x+9)? HELP NEEDED!!!!
Kipish [7]

Answer: 0, 4, -9

Set the equation equal to zero.

x(x - 4)(x + 9) = 0

Solve for x by setting each factor equal to zero.

The factors in the equation are x, (x - 4), and (x + 9).

  • x = 0
  • (x - 4) = 0

        x = 4

  • (x + 9) = 0

        x = -9

The zeros of the function are 0, 4, and -9.
