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
Answer:
a=7 b=24 c=25
Step-by-step explanation:
Leg a=7
Leg b=24
According to Pythagorean theorem: a^2+b^2=c^2
49+576=c^2
C^2=625
c=25

We need to find LCM of the denominators
It is found to be 24
We get the fractions (4+9)/24= 13/24
Answer:
The COP is 0.5
Step-by-step explanation:
First we must find the slopes.
12.50/25 = 0.5
17.50/35 = 0.5
The COP is 0.5
