If it drops 2 degrees every hour and the time is 12:00 it would take 6 hours to get the temperature to 0 degrees and if it wants the temperature to get to -4 you need 2 more hours so it would take 8 hours and be 8:00 by the time it got to -4

Two rectangles have the same width. One is 12 units long and the other is 8 units long. The area of the first rectangle is 320 s
Paraphin [41]

Answer:

80

Step-by-step explanation:

let w = the width of the rectangles

then

12w = the area of one rectangle

8w = the area of other

:

12w - 8w = 320

4w = 320

w = 320/4

w = 80 units wide

;

:

Check

12 * 80 = 960

8 * 80 = 640

--------------

difference: 320

Answer:

The answer is (0,-5)

Step-by-step explanation:

The reflection of the y-axis means inverted vertically (x will be inverted). This is a linear equation, so the y-intercept will stay the same, while every solution to the equation is inverted on the x-axis.

I swear to you I'm correct, trust.

Answer:

-1/2 and 2

Step-by-step explanation:

Since you need y=mx+b you have to convert your equation to match this

So, 3x+6y=12

Subtract 3x from both sides to get the y term on the left side alone.

This leaves 6y=-3x+12

From there divide 6 from both sides to give you your y term alone on the left side completely.

That leaves you with y=-1/2x+2

Meaning your M=-1/2 and your B=2

Your graph then should have the start point be at y=2 from there move -1 spaces down the y axis, and go to spaces to the right. Making your line move between r and n
