Slope between the points (x1,y1) and (x2,y2) is
(y1-y2)/(x1-x2)
given
(8,10) and (1,5)
(x,y)
x1=8
y1=10
x2=1
y2=5
slope=(10-5)/(8-1)=5/7
slope=5/7
Answer:
The average rate of change for the given function, from x = −3 to x = 7 will be:
Step-by-step explanation:
Given the table
x f(x)
-3 50
3 10
7 0
As the interval is from x = -3 to x = 7.
so
at x₁ = -3, f(x₁) = 50
at x₂ = 7, f(x₂) = 0
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [0 - 50] / [7-(-3)]
= [-50] / [7+3]
= -50 / 10
= -5
Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:
One solution which would be 1.5 or 3/2 same thing
Answer:
B. x = -4
E. x = 10
Step-by-step explanation:

1 1/2 as an improper fraction is 3/2
3/2x3/2=9/4
9/4 is 2.25 so 2.25 yards
