Find (f•f) (0)<br> F(x)=3x-2
NNADVOKAT [17]

Answer:  (f·f)(0) = 4

              (fof)(0) = -8

<u>Step-by-step explanation:</u>

f(x) = 3x - 2

(f·f)(x) = (3x - 2)(3x - 2)

         = 9x² - 12x + 4

(f·f)(0) = 9(0)² - 12(0) + 4

          = 4

(fof) = 3(3x - 2) - 2

       = 9x - 8

(fof)(0) = 9(0) - 8

           = -8

Please help ;-; <br> Solve for the simultaneous equation….<br> 5x+y=17<br> X+y=3
Svetach [21]

<u>Given Equation</u>:-

  • 5x+y=17 . . . . . . . . 1
  • x+y=3 . . . . . . . . . . 2

<u>To find</u> :

  • value of x
  • value of y

<u>Solution</u> :

<u>Let's start with equation 2</u>:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

  • 5x+y=17
  • 5x + (3 - x) = 17
  • 5x - x + 3 = 17
  • 4x + 3 = 17
  • 4x = 17 - 3
  • 4x = 14
  • x = 14/4
  • x = 7/2
  • x = <em>3.5</em>

<u>Now Let's find value of y</u><u>:</u>

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = <em>0.5</em>
