A committee raised 7/9 of their target goal last year and another 1/9 of the goal this year. What fraction of their goal has bee

Neporo4naja [7]

First, find 40% of 3,000:

0.40 * 3000 = 1200

So they raised 1200 so far.

Now subtract 1200 from the total they want to raise:

3000 - 1200 = 1800

So they need $1,800 more to meet their goal.

Use f(x) = 2x-9 and g(x)=9-x^2 to evaluate g(f(3))

Keith_Richards [23]

Answer:

g(f(3)) = 0

Step-by-step explanation:

f(x) = 2x - 9

f(3) = 2(3) - 9

f(3) = -3

g(-3) = 9 - (-3)^2

g(-3) = 9 - 9

g(-3) = 0
