Sarah has been running a dog-walking business since 2010. She walks dogs twice a day, takes them to the park, and returns them to their homes. Each year, she has increased her fee by the same amount. The table shows what Sarah charged each customer for two given years of her business:
Year Annual Dog-walking Fee
2010 $350
2014 $750
A. What is the rate of change and initial value for Sarah’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Sarah charges each year.
Answers
Answer:
Step-by-step explanation:
A. The Initial value is the starting value of her business which can be considered $350 since that is what she made the first year. The Slope can be calculated by subtracting the end profit from the initial profit and then dividing by the result of subtracting the end year by the initial year like so...
$350 initial value
[tex]\frac{750 - 350}{2014 - 2010} = \frac{400}{4} = \frac{100}{1 year} =[/tex] $100 a year increase
B. The equation for this scenario would be y = 100x + 350
Answer:
100 each year and y=100x+350

Solve the following system of equations algebraically using the ELIMINATION METHOD. Show all work.
x-3y=1
3x-5y=11
Answers
Answer:
(7,2)
Step-by-step explanation:
Multiply the first equation by -3
(x-3y=1) = -3x+9y=-3
Combine like terms with the new equation and the second equation
(-3x+9y=-3) + (3x-5y=11) = 4y=8
Divide each side by 4
4y/4=8/4
y=2
Plug in 2 for y in any equation. It doesn’t matter which one
x-3(2)=1
Distribute
x-6=1
Add 6 to both sides
x-6=1
+6 +6
x=7
Answer: x = 7 y = 2
(7, 2)
Step-by-step explanation:
Multiply the first equation by -3 and the second by 1:
-3(x - 3y = 1)
1(3x - 5y = 11)
Becomes:
-3x + 9y = -3
3x - 5y = 11
Add the equations to eliminate x:
-3x + 9y = -3
3x - 5y = 11
4y = 8
Solve for y by dividing by 4:
4y/4 = 8/4
y = 2
Now we plug in y to the first equation:
x - 3 ( 2 ) = 1
x - 6 = 1
Add 6 to both sides:
x - 6 + 6 = 1 + 6
x = 7

Marty and Adam want to share 8/10 feet of rope, equally. What amount of rope should each person get?
Answers
Answer: 2/5 feet
Step-by-step explanation:
From the question, we are informed that Marty and Adam want to share 8/10 feet of rope, equally.
The amount of rope that each person would get would be calculated by dividing 8/10 by 2. This will be:
= 8/10 ÷ 2
= 8/10 × 1/2
= 8/20
= 2/5
Therefore, each person gets 2/5 feet of rope.

Answer:
[tex]\frac{20}{36}[/tex]
Step-by-step explanation:
the total amount of squares within this square is 36
and the number of shaded squares would be 20
so if 20 squares out of 36 squares are shaded, then the fraction is
[tex]\frac{20}{36}[/tex]
or 55.56%
(to find percentage multiply [tex]\frac{20}{36}[/tex] by 100)
Answer:
5/9
= 55.56% ( to the nearest hundredth).
Step-by-step explanation:
The total number of little squares in the large square = 6*6 = 36.
Total number of shaded squares = 2*6 + 2*4
= 12 + 8 = 20.
So the fraction of shaded part
= 20/36
= 5/9.
As a percentage this is 5*100/9
= 55 5/9%
= 55.55..... %
