The cheetah is running initially at 27.5 because 70 - 42.5 = 27.5 mph
FORMULA: AREA = LENGTH X WIDTH
with this we can proceed so the area is 20
the length is 40 inches and
answer is : width ----18.94---
Slope intercept form isy=mx+b
m=slope
b=y intercept
ok so to find the slope when given 2 points you do
slope=(y1-y2)/(x1-x2)
(x,y)
(-1,-9)
(2,6)
x1=-1
y1=-9
x2=2
y2=6
subsitute
slope=(-9-6)/(-1-2)
slope=(-13)/(-3)
slope=13/3
y=13/3x+b
subsitute a given point to find b
(2,6)
x=2
y=6
6=13/3(2)+b
6=26/3+b
subtract 26/3 from both sides
6-26/3=b
6=18/3
18/3-26/3=8/3
8/3=b
the equation si
y=(13/3)x+8/3
