Answer:

A) y = 5x + 32

B) y = -4x -22

We multiply B) by -1

B) -y = 4x + 22 then we add it to A)

A) y = 5x + 32

9x + 54 = 0

x = -6

Substituting x = -6 into A) we get

A) y = 5*-6 +32

y = 2

Answer is c. (-6, 2)

How to write the ratio of the amount of time spent playing video games to the amount of time spent watching television
Pani-rosa [81]

Both values need to be in the same usable form. So, I would convert the two values into minutes. That leaves you 10 minutes of video games and 60 minutes of television. This ratio would be 10/60 or 10:60. Simplified would be 1/6 or 1:6.

70 POINTS!

You can solve this question with pythagorean theorem > {a}^{2} + {b}^{2} = c^{2}

Based on the information, you already have one side (a or b, doesn't matter, 12) and the hypotenuse (the cut, c, 15)

So: 
1. 12^{2} + b^{2} = 15^{2}
2. 144+b^{2} = 225
3. b^{2} = 225 - 144 = 81
4. b=  \sqrt{81}
5. b=9
