Answer:
Step-by-step explanation:
Factor out comon Term -1
Factor 
Use the rational root theorem
The dividers of 
: 1, 5, The dividers of 
: 1
Therefore, check the following rational numbers: ±
is a root of the expression, so factor out 
First you will get the sale price.
you need to convert the percentage to a decimal and to do that you move the decimal over twice:
30% = .30
then multiply the CD price by the decimal
$14.00 X .30 = $4.20
then you have the sales price but you need to find the tax price
to do that you move the decimal of the tax percentage over twice
7% = .07%
then multiply by the price after the sale included
.07 X $4.20 = $0.29
you have how much the tax would be
to get the total price you add the tax to the sales price
$0.29 + $4.20 = $4.42
the price you would be paying for this CD including tax is $4.42
Answer:
p = 
Step-by-step explanation:
change the mixed number to an improper fraction
- 2 
= - 
, hence
- p = - 3 ( multiply both sides by 7 )
- 15p = - 21 ( divide both sides by - 15 )
p = 
=
The answer is your 3rd option:
y = -40x + 200
