Answer:
f(x)=-2x+9 g(x)=-4x^2+5x-3Now, f o g (x) = f{g(x)} = f(4x^2+5x-3) = 2(4x^2+5x-3) + 9 = 8x^2+10x-6 + 9

Answer:
20 = 6m or m = 20/6 = 10/3
Step-by-step explanation:
Let's say Samantha has s marbles and Paul has m marbles.
We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.
Substitute 20 in for s:
20 = 6m
m = 20/6
Thus, the equation is m = 20/6.

Answer:
$23.952, since money is always rounded up $23.96
Step-by-step explanation:
the first step is to get the total value of her purchases, thus we add 16.99 + 12.95 to get 29.94
since she will receive a 20% discount that means that she will be paying 80% of the total value
next we set up the ratio as follows:
portion paid / total = x/29.94 = 80/100
solving the ratio gives you 23.952
