Answer:
Step-by-step explanation:
1) So -8+2v<2, 2v<10, v<5. That means that at "5" on the axis, you'll draw a circle that's <em>not</em> filled in (because it's <5, not 
5) and then draw a box-y thing to the left. Sorry, can't really describe it, but if you look at the picture attached, you'll understand
2) -12m-8-5m-7m, so -12m-8-12m, -80. This one doesn't have a variable... so you can't really graph it?
The slope 3 is and the y-intercept is 6.
Here's the equation for one year:
0.0129(680) + 680
But because it is 3 years:
3(0.0129(680)) + 680
0.0387(680) + 680
We can make it simpler:
1.0387(680)
Multiply:
706.316
We can round up:
She will have $706.32, and earn $26.32
11. 28*21 = 588 cubic feet
12. 16*9/3 = 48 pi ~150.72 ~ 151 cubic inches
13. 9*9*14/3 = 378 cubic yards
C.the diagonals are perpendicular i think :D
