Look at this:

2x+$2,000=$28,000
2x=$28,000-$2,000
2x=$26,000
x=26,000 divided by 2
x=$13,000

P1 +P2= 28 .     ----Equation 1
P1+2= P2 .       -------Equation 2 .          I abbreviate the thousands of $ 

Using substitution
P1+(P1+2)=28
2P1 +2=28
P1=13
then substitute into equation 2 we get
13+2=p2
P2=15

Therefore one is $15,000
and the other is 13,000

Smaller is 13,000!!!

. Write an equation that is perpendicular to y=2x – 1 and has y-intercept of -3
blagie [28]

The answer is very simple .

First you need to determine the slope, which is the reciprocal of the first line.

Then,

y = mx + b

m => -1/m

The perperdicular line has a new slope equal to m = -1/2

In the formula (y - y1) = m ( x - x1 ) + b , you should sustitude this value.

So the final equation will be

-3 = -1/2 (0) + b

b = - 3

y = (-1/2)x - 3

That is the solution

Someone help please!!!

Answer:

A. P - Q

Step-by-step explanation:

Q(x) = (x³ + 2x² + 3)(x² -2)

= x⁵ - 2x³ + 2x⁴ - 4x² + 3x² - 6

P - Q = (x⁵ - 2x³ + 2x⁴ - 4x² + 3x² - 6) - (x⁴ + 3x³ + 2x² - x + 2)

P - Q = x⁵ - x⁴ + 2x⁴ - 3x³ - 2x³ - 2x² - 4x² + 3x² + x - 2 - 6

P - Q = x⁵ + x⁴ - 5x³ - 3x² + x - 8

An online music store offers 5 downloads for $6.25.Another online music store offers 12 downloads for $17.40.Which store offers
Anon25 [30]
Well, what you have to do is find the unit rate for each one of those prices and how you do that is by dividing each price by the downloads

so $6.25 divided by 5= $1.25

and then $17.40 divided by 12= $1.45


so that means the one with $6.25/5 downloads has a better deal!
