F(x) = ( x + 3 ) ^2 + 78 is your answer.
Answer:
x = - 5
Step-by-step explanation:
Given
5x + 7 = 2x - 8 ( subtract 2x from both sides )
3x + 7 = - 8 ( subtract 7 from both sides )
3x = - 15 ( divide both sides by 3 )
x = - 5
Here are the calculations for Super Sport:
[12 ($72.50 x 0.8)] 1.065 = $741.24
Here is the math for Double Dribbles:
[12($54.75 x 1.09)] + (12 x $5.99) = $788.01
$788.01 - $741.24 = $46.77
The difference in price is $46.77.
You just have to divide the 1/2 a pound by 8, or equivalently multiply by (1/8):
(1/2)*(1/8) = 1/16 of a pound
Answer: 17
Steps:
1. Plug in (3) into “x” of the g(x) equation:
g(3) = (3)^2 + 4
g(3) = 9 +4
g(3) = 13
2. Plug in g(3) value into “x” of the f(x) equation:
f(g(3)) = x + 4
f(g(3)) = 13 + 4
f(g(3)) = 17
