x² + 3x = x + 6 + x²

<u>-x²        </u>    <u>          -x²  </u>

      3x = x + 6

  <u>    -x </u>   <u>-x      </u>

     2x =      6

     \frac{2x}{2} =      \frac{6}{2}

      x =    3

melamori03 [73]

Answer:

D. 32

Step-by-step explanation:

For this problem, we simply plug -9 in for x in f(x):

f(x)=\frac{1}{3} x^2+5  ⇒  f(9)=\frac{1}{3} *(9^2)+5=\frac{1}{3} *81+5=27+5=32

Thus, the answer is D. 32.

Hope this helps!
