y = 2x + 5

y = -3x - 10 

2x + 5 = -3x - 10

5x = -15

x = -3

x = -3

y = 2(-3) + 5

y = -1

(x, y) = (-3, -1)

As for the TRUE or FALSE question, I believe a system of equation is just any collection of equations, but my vocab skills are trash so I wouldn't trust it. 

I hope this helped. :)))

15 - 9 = 6

15 + 9 = 24. 

If degenerate triangles are allowed, then the interval is [6, 24]. 

If non including degenerate triangles, the interval is (6, 24).

I hope this helped. :)))

26 * .5 = 13

28 * .25 = 7

30 * .2 = 6

6 + 13 + 7 = 26.

26 total yellow jelly beans. 

26 + 28 + 30 = 84 total jelly beans. 

26/84 = 0.30952380952

Which is about 31%

I hope this helped. :))

It seems like I may have made a mistake on this answer. CPhill has the correct one. :)))

I'm sorry.

The ratio of sides is 3, 4, 5. 

So BED sides are 1, 4/3, 5/3. 

and BAE sides are 9/5, 12/5, 3.

The ratio between those sides are 9/5, so the area is just 81/25. 

Our final answer is 81/25.

I hope this helped. :)))

Volume of a sphere is (pi)*(r^2)*(h), where r is raduis, h is height, and pi is 3.14. 

Diameter is 24/2 = 12

We just need to plug everything in. 

(3.14)*(12^2)*(14) = 6330.24

5.8pi * 10.5 = 60.9pi

So the area of the plastic lable is 60.9pi.

1/9*|5a + 2| < 1

|5a + 2| < 9

-9 < 5a + 2 < 9

-11 < 5a < 7

-11/5 < a < 7/5

a = (-11/5, 7/5)

I hope this helped. :)))

Every week, Josie will do 2 more tests than Dustin. 

He's 8 behind so he'll need 4 weeks. 

4*3 + 3 = 15

In 4 weeks, the children will have each passed 15 test. 

I hope this helped. :)))

(14+10)*16 = 384. 

384/250 = 1.536

So he needs 1.536 gallons of paint. :)))
