Answer:
Step-by-step explanation:
<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>
<u>The slope is:</u>
- m = (-8 - 2)/(-1 - 1) = -10/-2 = 5
<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>
- 2 = 5(1) + b
- b = 2 - 5
- b = -3
<u>The line is:</u>
<u>Point (x, 17), substitute y-coordinate and solve for x</u>
- 17 = 5x - 3
- 5x = 17 + 3
- 5x = 20
- x = 20/5
- x = 4
The answer is 30.
You need to use sine here
So:
The answer for this is 42. just subtract 152 from 68 and then divide that by 2.
Answer:
72
Step-by-step explanation:
I have a weird way of doing it
so if 18 is 25%
18+18=36
then 36 would be 50%
36+36=72
so then 72 would be 100%
72*.25=18
