Answer:
3.6%
Step-by-step explanation:
We are solving the above question, using the simple interest Formula:
I = PRT
Where
I = Interest = $9
P = Principal = $150
R = Interest rate = ??
T = Time in years = 20 months
We convert this to years
12 months = 1 year
20 months = x
x = 20/12
x = 1.67 years
Hence, making R the subject of the formula
R = I/PT
R = 9/150 × 1.67
R = 9/250.5
R = 0.0359281437
Converting to percentage
R = 0.0359281437 × 100
R = 3.59281437%
R = 3.6 %
The simple interest rate she is earning is 3.6%
The inverse of the function is y = 
In order to find this, you must start by switching the y and x values. Once you do this, you can solve for the new y value and that will be in inverse. The work is done for you below.
y = 2x^2 + 2 ---> switch x and y
x = 2y^2 + 2 ---> subtract 2 from both sides
x - 2 = 2y^2 ---> divide both sides by 2
= y^2 ---> take the square root of both sides.
= y

<u>Corrected Question</u>
Matt makes $80 a month mowing lawns. His friend James also mows lawns, but he makes x dollars less per month than Matt does. James makes a total of $816 per year. How much less each month does James make than Matt? Solve the linear equation to find the value for x
. Remember that x represents how much less per month James makes than Matt
Equation: 12(80 – x) = 816
Answer:
x=$12
Step-by-step explanation:
To solve the given equation
12(80 – x) = 816
First, we distribute:
960-12x=816
Collect like terms
12x=960-816
12x=144
Divide both sides by 12
x=12
Therefore, James makes $12 less than Matt every Month.
