Answer:
- 22
Step-by-step explanation:
A fall of 
degree = 0.5 degrees is represented as
- 0. 5 degrees
The temperature at 2 : 00 is therefore
- 21.5 - 0.5 = - 22 degrees
-4,6 I believe is the answer!!!!!!!!
First, you have to find the midpoint of the segment. Using the midpoint theorem, (which is (x1+x2)/2, (y1+y2)/2 ) the midpoint of that segment in (3,-1)
Next find the slope of the segment 1,0 and 5,-2 using rise over run or deltax / deltay which is a fancy way of saying change in x over change in y.
The slope is 4/2 or 2
When a line is perpendicular to another the slope is the negative reciprocal so the slope of our new line will be -1/2
Now plug in the coordinate (3, -1) to find the y-intercept and the equation of that line will be complete
so -1 = -1/2 (3) +b
-1= -1.5 +b
0.5 = b
The final equation will be -1/2x + 0.5 =y
hope this helps:)
Use synthetic division. check attachment for work and steps.
If you imagine this line on a grid, you get 18 units below the 0 and 18 units above the 0, which means you must add them together and get your answer as 36 units. I hope this helps!
