Answer:

i belive that the awnser is y=-1.25x+1000

Step-by-step explanation: you want to get y by itself so you would subtract x from both sides leaving you with

56y=-70x+56,000

then you would devide both sides by 56 leaving you with

y=-1.25x+1000

The answer would be y=-1.25x+1000 or y=-5/4x+1000. They are both the same just one is a fraction and one is a decimal.
First you’d move the variable to the right so it would be 56y=56000-70x. Then you would divide both sizes by 56 and you would get y=1000-5/4x. After that you would just reorder them and get y=-5/4x+1000

prisoha [69]

Answer:

9 11/12

Step-by-step explanation:

1st step- convert the mixed number into improper fraction to convert it just multiply the denominator with the whole number and after you get the product, add the product with the numerator and then same with the other set of fraction

2nd step- multiply the numerator by numerator and denominator by denominator

3rd step- after you multiply it simplify it

Suppose the equation for line A is given by 2x = 5y – 25. If line A and B are perpendicular

Ludmilka [50]

The required equation of line B is 2y+5x=-2

The equation of a line in point-slope form is expressed as:

y-y0 = m(x-x0)

m is the slope of the line

(x0, y0) is the point on the line

Given the line A expressed as:

2x = 5y – 25

Rewrite in standard form

5y = 2x + 25

y = 2/5 x + 5

The slope will be 2/5

The slope of the perpendicular line will be;

$M = \frac{-1}{(2/5)}\\M = \frac{-5}{2}$

Substitute the point (-6, 14) and slope -5/2 into the equation above to get the required equation of line B

$y-14=-5/2(x+6)\\2(y-14) = -5(x+6)\\2y-28=-5x-30\\2y+5x=-30+28\\2y+5x=-2\\$

Hence the required equation of line B is 2y+5x=-2

Answer:

- Point of intersection = (4, 360)

- The meaning of the intersection (4,360) means that when 4 hours of repair has passed for either service, the price of each service will be the same ($360).

- If it takes 3 hours to fix your car: Amy's Auto Repair will be the cheapest of the two services.

Step-by-step explanation:

Set both functions equal to each other:

100+65x = 40+80x

Subtract from both sides:

65x-80x = -15x

40-100 = -60

Set the two new numbers equal to each other:

-15x = -60

Solve this equation:

-60 / -15 = 4

This means the answer to the x intercept is 4.

...Now we need to find the y intercept...

To figure this out, you need to substitute the x-intercept (4) in for any x in the equation:

100+65(4) = 40+80(4)... simplify... 100+260 = 40+320

Now solve this:

100+260 = 360 --- and --- 40+320 = 360...

360 = 360...this means the y-intercept is 360.

So, the answer to question 1 is (4,360)

Why Amy's Auto Repair shop will be cheaper than Mike's Repair Shop after 3 hours of service:

3 hours of Mike's service: 100+65(3) = $295

3 hours of Amy's service: 40+80(3) = $280 - CHEAPER

I hope this helps :)
