Answer:
She would have to do 219 haircuts in a month for the costs to be the same, which would be $428.
Step-by-step explanation:
To find this we take the costs of the first place.
$438
Next we can look at the costs of the second place using x as the number of haircuts she'd do.
2x
Now we can set the two equal to each other to find the number of cuts.
438 = 2x
219 = x
Answer:
32
Step-by-step explanation:
32 is the constant of proportionality. Its represents thr average number of miles per gallon.
The equation y=x-2 do not represents the line that passes through the two point, since for example -4-2=-6, not 10. So (-4,10) is not on the line.
Let find the equation of the line:
First compute the slope using formula:
<span> </span>

So the equation is in the form:

For x=-4 we get the equation:

Solving the above equation for s we get:

The equation then is the following:
The correct answer then is equation 2 and equation 3.
The answer is 5.77 i hope this helps
Answer:
66.67%
Step-by-step explanation:
75 /100 = .75
.75n = 45
45/.75 = 60
60 is n
60/90 = .666667
.666667 * 100 = 66.67%
