Answer:

2y + 2x = 0

Step-by-step explanation:

First you have to find the slope of the line.

Parallel lines have same slope

2y = -2-2x

y=-1-1x, y=-1x-1

slope = -1

Use point slope formula

y-y=m(x-x)

y-(-9) = -1(x-9)

y+9 = -1(x-9)

y+9 = -1x+9

y = -x

y + x = 0

2y + 2x = 0

Calculate X3 dx . A.×2 + c B. 3X2 + c c . x4 + c D . x4/4+c

olga nikolaevna [1]

$\LARGE \int x^3 dx = \frac{x^4}{4}+C$

So the answer is choice D. You can check this by differentiating the right hand side and you'll get x^3 back again.

This answer can be found by using the power rule for integrals. That rule is

$\LARGE \int x^n dx = \frac{x^{n+1}}{n+1} + C$

Frank is trying to factor y^2+6y-27 . He has determined that one factor is (y + 9). What is the other factor? A. y – 27 B. y – 6

beks73 [17]

The other factor is (y - 3). If you multiply the two terms together, you will end up with $y^2+6y-27$ :

$(y - 3)(y + 9) \\ y^{2} +9y-3y-27 \\ y^2+6y-27$

Answer:

jacket 80

shoes 32 and 16

shirt 9 , 8.04, 4.08

Step-by-step explanation:

you need to multiply the original cost by the percentage off and then subtract from the original

example

Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40. but you would have to subtract the 40 from 120 giving you 80
