Answer: x-3</h3>
Since p(3) = 0, this means x = 3 plugs into p(x) to get 0
We can write p(x) as p(x) = (x-3)q(x) where q(x) is some other polynomial that multiplies with (x-3) to lead to x^3-3x^2-x+3
Let's plug in x = 3 and see what happens
p(x) = (x-3)q(x)
p(3) = (3-3)q(3)
p(3) = 0*q(3)
p(3) = 0
No matter what the result of q(3) was, it doesn't matter because it multiplies with 0 to get 0.
The general rule is: if p(k) = 0, then x-k is a factor of p(x). This is a special case of the remainder theorem.

Answer:
when expenses are greater than $433.33
Step-by-step explanation:
set up equations for each plan
let 'x' = prescription costs
Plan 1: y = 150 + .5x
Plan 2: y = 280 + .2x
150 + .5x = 280 + .2x
.5x = 130 + .2x
.3x = 130
x = 433.33
i checked my answer by graphing each equation and $433.33 is the break-even point where each plan would have the same costs but, after that, the expenses for Plan B are less
Answer:
x> 1
Step-by-step explanation:
X-7>-6
Add 7 to each side
X-7+7>-6+7
x> 1
