Jenna wants to open a salon and must choose a location. At Location A, she will pay $1200 per month and charge $45 per haircut.
anzhelika [568]
Profit=revenue-cost

pA(m,h)=45h-1200m

pB(m,h)=60h-1800m

Profit is the same when pA=pB so

60h-1800m=45h-1200m

15h=600m

h=40m

So 40 haircuts per month at either location results in the same profit of $600 per month.

Find f(x) if it is known that f(2a−1)=7a−13.
sattari [20]

Answer:

f(x)=3.5x-9.5

Step-by-step explanation:

Given:

The given function in terms of 'a' is given as:

f(2a-1)=7a-13

In order to determine f(x), we need to make 2a-1 equal to 'x' and find the value of 'a'. Therefore,

2a-1=x\\2a=x+1\\a=\frac{x+1}{2}

Now, plug in the value of 'a' on both sides, we get:

f(2\frac{x+1}{2}-1)=7\frac{(x+1)}{2}-13\\f(x+1-1)=3.5(x+1)-13\\f(x)=3.5x+3.5-13\\f(x)=3.5x-9.5

Therefore, the expression for the function in terms of 'x' is:

f(x)=3.5x-9.5

Solve x2 = 12x – 15 by completing the square. Which is the solution set of the equation?
Nady [450]
For this case we have the following polynomial:
 x ^ 2 = 12x - 15

 The first thing to do is to place the variables on the same side of the equation.
 We have then:
 x ^ 2 - 12x = -15

 We complete the square by adding the term (b / 2) ^ 2 on both sides of the equation.
 We have then:
 x ^ 2 - 12x + (-12/2) ^ 2 = -15 + (-12/2) ^ 2

 Rewriting we have:
 x ^ 2 - 12x + (-6) ^ 2 = -15 + (-6) ^ 2

x ^ 2 - 12x + 36 = -15 + 36
 
(x-6) ^ 2 = 21
 x-6 =+/- \sqrt{21}
 Therefore, the solutions are:
 x = 6 - \sqrt{21}
 x = 6 + \sqrt{21}
 Answer:
 
the solution set of the equation is:
 
x = 6 - \sqrt{21}
 x = 6 + \sqrt{21}
