On a coordinate plane, 1,2 and -2,2 would be 3 units apart.
The inverse of the function f(x) is x/4 + 3/28
The function is given as:
f(x) = 4x - 3/7
Set f(x) = y
y = 4x - 3/7
Swap the positions of x and y
x = 4y - 3/7
Make y the subject
4y = x + 3/7
Divide by 4
y = x/4 + 3/28
Hence, the inverse of the function f(x) is x/4 + 3/28

The day is 35 when they get to see each other at the beach after finding the LCM of the numbers 7 and 5.
It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
Last summer, Karl went to the beach every 5 days.
Antonia went to the beach every 7 days.
To find the day they get to see each other at the beach:
Find the LCM(lowest common factor) of 7 and 5:
7: 7, 14, 21, 28, 35,
5: 5, 10, 15, 20, 25, 30, 35
The common number is 35.
Thus, the day is 35 when they get to see each other at the beach after finding the LCM of the numbers 7 and 5.

Answer:
The most cost effective company will be Painting USA that charge $700 to paint Paul house .
Step-by-step explanation:
As given
Paul is going to have the exterior of his home painted.
Painting USA charges $75.00 to come out and evaluate the house plus $25.00 per hour of labor.
If it takes 25 hours to paint Paul’s house.
Total amount charge by Painting USA = Painting USA charges for come out and evaluate the house + Cost of per hour of labor × Total hours take to paint Paul house .
Total amount charge by Painting USA = 75 + 25 × 25
= 75 + 625
= $ 700
As given
Upscale Home Painting does not charge to evaluate the house. However, they charge $40.00 per hour.
Total amount charge by Upscale Home Painting = Cost of per hour of labor × Total hours take to paint Paul house
= 40 × 25
= $ 1000
Therefore the most cost effective company will be Painting USA that charge $700 to paint Paul house .
