Answer:

  (x, y) = (5, 3)

Step-by-step explanation:

We can use the second equation to substitute for y in the first.

  x = 17 -4(x -2)

  5x = 25 . . . . . . . . eliminate parentheses, add 4x

  x = 5

  y = 5 -2 = 3

The solution is (x, y) = (5, 3).

F(x)=9x^2 <br><br> g(x)= sqrt 12-x/3<br><br> (f o g)(-4)
Slav-nsk [51]

f(x)=9x^2 \\ g(x)=\frac{\sqrt{12-x}}{3} \\ So,first step is to write (fog)(-4)) =f[g(-4)] \\

Now we start from inner paranthesis ,we need to first find value of g(-4) =\frac{\sqrt{12-(-4)}}{3}\\ =\frac{\sqrt{12+4}}{3}\\&#10;=\frac{\sqrt{16}}{3}\\&#10;=\frac{4}{3}\\&#10;(fog)(-4)) =f[g(-4)] =f(\frac{4}{3}) =9(4/3)^{2} =9*(16/9) =144/9 =16
