Answer:
Step-by-step explanation:
Let
x ----> the number of days
y ----> the amount of money remaining in dollars
we have the points
(2,12.10) and (5,2.50)
step 1
Find the slope m
The formula to calculate the slope between two points is equal to
substitute the values
----> is negative because is a decreasing function
step 2
Find the equation of the line in slope intercept form
where
m is the slope
b is the y-intercept
with the slope m and the point (2,12.10) find the value of b
substitute
solve for b
substitute
14 miles Substitute AB = 3 and BC = 11 in above equation.

Answer:
The grade of this sixth and (final) test <u>would be 91</u>.
Step-by-step explanation:
This is an arithmetic series since each time the data is increasing by the common difference of 4, and we already know a₁ which is the first term in the sequence is 71, therefore we can say:
a₁ = 71
r = 4
a₆ = the sixth term that needs to be found out
n = 6
Formula of an arithemetic series:
aₙ = a₁ + r(n - 1)
a₆ = 71 + 4(6 - 1)
a₆ = 71 + 4(5)
a₆ = 71 + 20
a₆ = 91
Hence, the grade of this sixth and (final) test would be 91.
Hope this helps!
