<span>X/2 + 3/4 = 7/4
We want to isolate X by itself. Subtract 3/4 from both sides
X/2 = 4/4
X/2 = 1
Multiply both sides by 2 to cancel out the 1/2 on the same side of the X
X = 2</span>
A) Find the inverse of the function
s=0.04n+2500
s-2500=0.04n+2500-2500
s-2500=0.04n
s/0.04-2500/0.04=0.04n/0.04
25s-62,500=n
n=25s-62,500
Answer: The inverse of the function is n=25s-62,500
Is <span>the inverse a function?
Yes, the inverse is a function, a linear function.
</span>b) Use the inverse to find the same amount of merchandise sold if the employees salary was $2820 last month.
s=2,820→n=25(2,820)-62,500
n=70,500-62,500
n=8,000
Answer: The amount of merchandise sold was $8,000
X=90 degrees you can get the answer by adding up all the angles
Answer:

Step-by-step explanation:
Given
Represent Fred with F; Norman with N and Dave with D.


Required
Determine the arithmetic mean of F and N
First, we have that:

Substitute 44 for D

Subtract 44 from both sides


Arithmetic mean of F and N is calculated as follows:



Y should be 51. If you fill in the variables you get y=(9x5)+6, and once you solve you get y=51
