P(x) = 1/10
{x: 0 < x < 11}
Answer:
x = 4 ±
Step-by-step explanation:
x² - 8x + 16 = 3 ← the left side is a perfect square
(x - 4)² = 3 ( take square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±

Answer:
1.) y = 1.10(x – 1) + 1.35
Step-by-step explanation:
When x pounds of apples are purchased, the number of "additional" pounds is (x-1). The cost of those additional pounds is then added to the cost of the first pound to get ...
y = 1.10(x -1) +1.35
_____
<em>Comment on the function rule</em>
Personally, I think it is easier to write the rule as y = 1.10x +0.25, considering the first pound to have a $0.25 premium added to its otherwise $1.10 cost. This saves an operation when evaluating the formula for some value of x.
