Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given the points
The slope between two points
As the point-slope form is
substituting the values m = -9/10 and (8, -4)
Writing the line equation in the slope-intercept form
where m is the slope and b is the y-intercept
so the equation in the slope-intercept form will be:
subtract 4 from both sides
Therefore, the equation in the slope-intercept form will be:
Answer:
A =256 cm^2
Step-by-step explanation:
The perimeter of a square is 64 cm
P = 4s where s is the side length
64 = 4s
Divide by 4
64/4 = 4s/4
16 =s
The side length is 16 cm
The area of a square is
A = s^2
A = 16^2
A =256 cm^2

−3 − (−2)= -3+2 = -1
Answer:
Width = 80 ft and length = 85 ft.
Step-by-step explanation:
Let the width be x ft then the length is x+5 ft.
width * length = area, so
x * (x + 5) = 6800
x^2 + 5x - 6800 = 0
( x - 80)(x + 85) = 0
x = 80, -85
We ignore the negative so x = 80 ft.
Width = 80 and length = 80+5 = 85 ft.
