Bobby charges $10. per lawn he mows, and an additional $5. per hour.
a) Find the independent and the dependent variables.
b) Write a linear function that models the wage of Bobby per lawn.
c) If Bobby work for 3.5 hours on a lawn, how much does he earn?
Answer: a) the dependent variable is y, the amount he earns depending on x, the independent variable. x is the number of hours.
b) y = 5x + 10
c) Bobby earns $27.50 for the 3.5 hour job
Step-by-step explanation: use the function y=5x + 10 substitute 3.5 for x
y = 5(3.5) + 10
y = 17.5 + 10
y= 27.5
Rental car company A charges an initial fee of $35 plus $0.75 per mile. Rental car company B charges $0.50 per mile and an initial fee of $55. For what number of miles will the cost of both rental car companies be the same? True or False: 35 + 0.75x ≥ 0.5x + 55 be used to solve the real-world problem. If false, explain in detail what needs to be changed in the real-world problem so 35 + 0.75x ≥ 0.5x + 55 can be used to solve it.
Answer:
Let it be for x miles.
40+15+0.25x=45+0.35x
10 =0.1x
x=100
The mile is 45+0.35*100= 80 or 40+15+0.25*100 =80
Step-by-step explanation:
Answer:
x=100

1. Find the value for X in 15x + 5
2. Also find the value of X in 22x + 4
Answer:
For the first one the value of X will be 3 and the second one the value of X will be 5.5
Step-by-step explanation:
All you're really doing for expressions like this are dividing the whole number into the number with the variable. for example, i took 5 and divided it into 15x which gave me 3 so the X will equal 3. Hope I helped

Evaluate m + n for m - 9 and n = 7.
A 2
C 63
B 16
D 97
Answer:
The only thing I can think of is -2.
Step-by-step explanation:
-9 + 7 = -2
I'm not sure if you wrote the questions or the answers wrong, but if I'm reading it right the answer should be -2, not 2. Unless you meant to write 9 + -7, in which case the answer would be 2.

I NEED HELP CAUSE I'M STUCK AS HECK
Answer:
$1000
Step-by-step explanation:
So there is 10,000,000 dollars in the company for the annual employee bonus. There are 10,000 employees in this company. This seems like a simple division problem. So you divide 10,000,000 by 10,000 and you get 1,000. So with that being said each employee should receive $1,000 in total.
This may be wrong if so I tried my best
2. The Perimeter of a square is P. Which equation could be used to find its area (A)?
a. A = P2
b. A = (p/4)^2
c. A = 4P
d. A = (√p)^2
Answer:
A = (P/4)²
Step-by-step explanation:
Given
Perimeter = P
Required
Determine the area
First, we need to calculate the sides of the square using:
[tex]P = 4L[/tex]
Where L represents the length of the side
Make L the subject
[tex]L = \¼P[/tex]
Area is calculated as thus:
[tex]Area = L\²[/tex]
Substitute ¼P for L
[tex]Area = (\¼P)\²[/tex]
The composition of transformations sometimes results in figures remaining similar. (True or false)
Answer:

Write the equation of a line that is parallel to y =1/2x + 9 and goes through the point (-2,2)
Answer:
y = 1/2x + 3
Step-by-step explanation:
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 1/2x + b
2 = 1/2(-2) + b
2 = -1 + b
3 = b
y = 1/2x + 3
Best of Luck!

Solve the equation. If the equation is an identity, choose identity. If it has no solution, choose no solution. 8s−(5s+6)=12(20+6s)
Answer & Step-by-step explanation:
8s - (5s + 6)= 12(20+6s)
8s - 5s - 6 = 240 + 72s
3s - 6 = 240 + 72s
-246 = 69s
s= -246/69
s = - 3 13/23
