It's pretty simple once you understand how to do it. First we have to find the change in the time. Since it started at 10:00 and went to 15:00 (military time is useful in these problems) the time has changed a total of 5 hours. And since this temperature increases 2.25 degrees each hour, we would multiply 2.25 by 5 which gets us 11.25. Then all we have to do next is add 11.25 and -3 which gets us 8.25 degrees as the answer.
Answer:
n=-25 and SU=100
Step-by-step explanation:
<u><em>Solve for n</em></u>
4n-18=32-6n
-2n=50
n=-25
<u><em>Solve for segment SU</em></u>
4(-25)-18+32-6(-25)=SU
-100-18+32+150=SU
-82+182=SU
100=SU
Answer:
the third one is the answer
Answer:
Plot the points (0,0) and (1,3) to make the line.
Step-by-step explanation:
We know that a linear equation is y=mx+b, m is the slope and b is the y-intercept. We can see that the slope is m=3, and there is no b meaning b=0. Since the y-intercept is 0 we can start from the origin (0,0). The slope is 3/1 or known as rise/run. You go up 3 and go right 1, making the second point (1,3). This should work.
