Answer:

y=-1/2x-8

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=-1/2(x-(-6))

y+5=-1/2(x+6)

y=-1/2x-6/2-5

y=-1/2x-3-5

y=-1/2x-8

The pound has three kinds of dogs: pit bull, chihuahuas and mutts. All but 23 of the dogs are pit bull, all but 17 are chihuahua

Georgia [21]

Answer:

There are 68 dogs in the pound.

Step-by-step explanation:

Number of pit bull dogs in a pound = P = 23

Number of chihuahuas dogs in a pound = C = 17

Number of mutts dogs in a pound = M = 28

Total number of dogs in a pound = T

$T = P+C+M=23+17+28=68$

There are 68 dogs in the pound.

Answer:

The expression of the area of rectangle ABCD as simplified polynomial will be:

$A=16x^2-8x$

Hence, the 2nd option is correct.

Step-by-step explanation:

As we know that the area of a rectangle can be obtained by multiplying the length by the width.

i.e.

$A=l\times w$

Given

The length of a rectangle ABCD = $l$ = $(x+5) + (3x) + (4x-9)$

The width of a rectangle = $w$ = $2x$

so the expression of the area of rectangle ABCD as simplified polynomial will be:

$A=l\times w$

$A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right]$

$=\left(\left(x+5\right)+\left(3x\right)+\left(4x-9\right)\right)\left(2x\right)$

$=\left(x+5+3x+4x-9\right)\times \:2x$

$=2x\left(8x-4\right)$

$=16x^2-8x$

Therefore, the expression of the area of rectangle ABCD as simplified polynomial will be:

$A=16x^2-8x$

Hence, the 2nd option is correct.

A shopping mall charges $30 per vehicle plus $2 per person as an admission fee. The total charge for a vehicle with x people is

Alecsey [184]

Changing the 30 to 10 is a 20 unit drop ( 30-10=20)
so the line would shift vertically down by 20
