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?
Answer:
13.31803792
Step-by-step explanation:
<u>Law of Cosines</u>
a= 8
b= 18
c= ?
c = 64 + 324 - 2 * 8 * 18 * cos(43)
cos(43) = 0.7313537016
<u>Order of Operations</u>
64 + 324 - 2 * 8 * 18 * 0.7313537016 = 177.3701339
<u>Square Root the answer</u>
= 13.31803792
When you plug in 3 in for y the equation is 3x + 6(3) = 24
3x + 18 = 24
subtract 18 from both sides
3x = 6
Isolate the x by dividing both side by 3
x = 2
We can set it up like this:
This states that Sam can drive 192 miles in 4 hours and 2220 miles in x hours. To solve, we can use cross-multiplication:
It will take Sam 46.25 hours to drive the whole trip, or 46 hours and 15 minutes.
