Answer: perm will cost $48
Step-by-step explanation:
Let x be cost of haircut
So perm will cost her 2x
So
x + 2x + 5 = 77
3x = 72
x = 24
Perm will cost 2x24 = 48
For the given function, the domain is D : { x ≥ 7} and the range is R: { y ≥ 9}
<h3>
How to get the domain and range?</h3>
Here we have a square root, remember that the argument of the square root must be equal or larger than zero, so the domain is such that:
x - 7 ≥ 0.
Solving for x we get:
x ≥ 0 + 7
Then the domain is:
x ≥ 7
To get the range, we evaluate in the minimum of the domain:
f(7) = √(7 - 7) + 9 = 9
Then the range is the set of all values larger than 9, because the function is increasing.
So the range is R: y ≥ 9.

A typical towel is the shape of a rectangle.
Rectangles have 2 opposite pairs of congruent (equal) sides.
To find perimeter, find the sums of all the sides.
The measures of the towel's sides are:
2 feet
2 feet
3/4 foot
3/4 foot
Add these together to find the perimeter.
2 + 2 + 0.75 + 0.75 = 5.5
The perimeter of the towel is 5.5 feet.
Hope this helps!

It is in decimal form, can you give a little more feedback as to what you are applying?
G (x) = -11/4 ...
that's your answer
