Answer:
Slope is equal to the change in y over the change in x , or rise over run.
m=change in y/ change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=0−(2)/9−(5)
Simplify.
m=−12
Step-by-step explanation:
Angles 6 and 7 are vertical angles
Step-by-step explanation:
l = length
w = width
l/w = 5/2
l = 5w/2
l×w = 1000ft²
(5w/2)×w = 1000
5w²/2 = 1000
5w² = 2000
w² = 400
w = 20ft
l = 5w/2 = 5×20/2 = 5×10 = 50ft
the length is 50ft.
the width is 20ft.
Answer:
x = - 6
Step-by-step explanation:
Given
= 3
Multiply both sides by 5 to clear the fraction
9 - x = 15 ( subtract 9 from both sides )
- x = 6 ( multiply both sides by - 1 )
x = - 6
