Using linear function concepts, it is found that he can correctly determine the hourly rate as follows:
subtract the supply fee, 15 dollars from the total cost, then, divide the difference by the number of hours.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, which can also be interpreted as the initial value of a function that is valid only for , such as is the case in this problem.
The flat fee is of $15, hence b = 15, then:
Philip uses the service for 3.5 hours for his spring cleaning, and his total is $232, hence when x = 3.5, y = 232, so we use it to find the hourly rate m.
Hence, the correct option is:
subtract the supply fee, 15 dollars from the total cost, then, divide the difference by the number of hours.

According to this law, when unemployment goes up by 1%, GDP drops by 2%. In the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the GDP drops by 6%. Thus the effect is a drop in GDP by 6%.
The answer is 4 3/8 boxes because 1 3/4 x 2 1/2 = 4 3/8.
Answer:
5² x 7 x 2
Step-by-step explanation:
350
= 35 x 10
= 7 x 5 x 5 x 2
= 5² x 7 x 2
Welp. I sure hope you like the Pythagorean theorem...
Top line:
One point is (-2,-2) while the other is (3,-3)
Thus the distance in between is sqrt((3-(-2))^2+(-3-(-2))^2)=sqrt(5^2+(-1)^2)=sqrt(26)
Most right line:
One point is (4,-6) while the other is (3,-3)
Thus the distance in between is sqrt((3-4)^2+(-3-(-6))^2)=sqrt((-1)^2+3^2)=sqrt(10)
Most bottom line:
One point is (1,-6) while the other is (4,-6)
Thus the distance in between is sqrt(4-1)^2+(-6-(-6))^2)=sqrt(3^2+0^2)=sqrt(9)=3
Most bottom left line:
One point is (1,-6) while the other is (-2,-4)
Thus the distance in between is sqrt((1-(-2))^2+(-6-(-4))^2)=sqrt(3^2+(-2)^2)=sqrt(13)
Lastly the most left line:
One point is (-2,-2) while the other is (-2,-4)
Thus the distance in between is sqrt((-2-(-2))^2+(-2-(-4))^2)=sqrt(0^2+(2)^2)=sqrt(4)=2
Thus to find the perimeter, we add up all the sides to get
sqrt(26)+sqrt(10)+3+sqrt(13)+2=16.8668 or B
