Answer:

C=87

Step-by-step explanation:

To isolate the variable, you need to take away -57 by adding it to -144.

Then, you'd see:

-n=-87

Next, you divide both sides by -1 to get 87

Help easy question!!
LenKa [72]

When you look at the x = 0 and y = -2, that is the y-intercept since the x = 0.

Then when you look at the second one, it goes right one and up four.

As rise over run, it would be 4 / 1 or simply 4.

The slope is 4 and the y-intercept is -2

Plug it in the equation: y = mx + b. M is the slope and B is the y-intercept.

y = 4x -2

How do know what the perimeter is and how to solve it
oee [108]
The perimeter is all the sides added up.

s1+s2+s3+s4= p

So, 12+ 6+ 8+ 17= the perimeter.

12+6+8+17 = 43

The answer is 43.

I hope this helps!
