Leticia recently rented an office space and now needs someone to do weekly cleaning. She received these bids from two different

cleaning services. Quick Clean charges a $30 cleaning supply fee for every visit and $20 per hour. Three Friends Cleaners provided the table below to show its cost. image 584f4e6957dd4bd891b08a92e88537ac Which statements comparing the costs of the two cleaners are true? Choose all that are correct. A If it takes 10 hours for Leticia's office space to be cleaned, Three Friends Cleaners is less expensive than Quick Clean. B If the cleaning costs for each company were graphed, the y-intercepts would be the same. C If it takes 5 hours for Leticia's office space to be cleaned, Three Friends Cleaners is less expensive than Quick Clean. D If the cleaning costs for each company were graphed, the graphs would intersect when x equals 6 hours. E Three Friends Cleaners charges $5 more per hour than Quick Clean.

Can you guys pls help me out with 16 and 17
nlexa [21]

Answer:

16. $ 4100

17. y = 10000 - 750x

Step-by-step explanation:

16)

As initial value is $ 5000, and salvage value is $ 500. That means in 5 years value decreased by 5000-500 = 4500 so ,

in 5 year value decreased =  4500

in 1 year value decreased =  4500/5 = 900

so per year 900 $ gets decreased from original price. So equation can be given as

V = 5000 - 900y

where V is value of a vehicle and y is number of year

So after 1 year value would be

V = 5000 - 900 x 1 = 5000 -900 = 4100 $

17)

initial cost of car = $ 10000

per year amount decreases by  =  $ 750

then equation can be given as

y = 10000 - 750x

where x is number of year and y is cost of car after x year.

Write the Equation of the line in slope intercept form<br> (0, -3), (7.5,0)
makkiz [27]

Answer:

Step-by-step explanation:

First, start off by solving for the slope using this formula:

\frac{y_{2} -y_{1} }{x_{2}-x_{1}  }

Then, plug in the values: \frac{0-(-3)}{7.5-0}

Solve the equation: \frac{3}{7.5}

That's your slope.

Then plug in one of the coordinates given in the problem for x and y and solve this equation:

y=\frac{3}{7.5}x+b

Hope that helped!!! :)

Find the percent of increase for 4 to 7. round to the nearest tenth if necessary. also someone please explain how to do this.
dem82 [27]

Answer:

75%

Step-by-step explanation:

The percent increase is calculated as

percent increase = \frac{increase}{original number} × 100%

increase = 7 - 4 = 3, thus

% increase = \frac{3}{4} × 100% = \frac{3(100)}{4} = 75%

Solve the system algebraically.<br> 3x - 2y - 1 = 0 y = 5x + 4 <br> What is the solution?
Bogdan [553]

Answer:

x=\frac{-9}{7}

y=\frac{-17}{7}

Step-by-step explanation:

We have been given the equation:

3x-2y-1=0

And y=5x+4

Second equation can be rewritten as:

5x-y=-4

We will solve the equations:

3x-2y=1      (1)

5x-y=-4       (2)

Multiply equation (1) by 5 and equation (2) by 3 we get:

15x-10y=5      (3)

15x-3y=-12       (4)

Now, subtract (4) from (3) we get:

-7y=17

y=\frac{-17}{7}

Now substitute y=\frac{-17}{7} in equation (1) we get:

3x-2{\frac{-17}{7}}=1

3x+\frac{34}{7}=1

21x=-27

x=\frac[-27}{21}

x=\frac{-9}{7}
