Answer:
12 1/4
Step-by-step explanation:
You would first add the fractions which will get you 5/4. then you will add the whole numbers which will get you 11. Then there is a extra number in 5/4 so you can tranfer it to the whole number which will become... 12 and then you will be left with 12 1/4
Constant rates are used to illustrate linear functions.
- The average rate of change is $9.0 per hour
- The function that models the table is:
- The amount earned in 7.5 hours is $67.5
<u>(a) The average rate of change</u>
This is calculated using:
So, we have:
Hence, the average rate of change is $9.0 per hour
<u>(b) A function that models the table of values</u>
Let x represent hours, and y represent the earnings.
So, we have:
Where:
m =Rate = 9.0
So, we have:
Expand
Represent as a function
Hence, the function that models the table is:
<u>(c) Amount earned for 7.5 hours</u>
This means that x = 7.5
So, we have:
Hence, the amount earned in 7.5 hours is $67.5

A. n = 500 and C = 10
Substitute values into the equation and solve for k.
10 = k + 2000/500
10 = k + 4
6 = k
b. n = 250 and k = 6
Substitute values into the equation and solve for C.
C = 6 + 2000/250
C = 6 + 8
C = 14
c. C = 8.5 and k = 6
Substitute values into the equation and solve for n.
8.5 = 6 + 2000/n
2.5 = 2000/n
n = 2000/2.5
n = 800
Answer:
11/2 = y
Step-by-step explanation:
You have it all but solved. Now, multiply both sides of the equation by 5/2, the inverse of the coefficient of y.
(5/2)(11/5) = (5/2)(2/5)y
11/2 = y
