So 15.90 is almost $16 so you will round up...
and 18 is almost 20
so that would be 20%of $16
so the best estimate would be around $3-$4
The rule for the reflection
rx-axis (x, y) → (x, –y)
ry-axis (x, y) → (–x, y)
<h3>Further explanation</h3>
A reflection is an example of a transformation
Reflection is the process of mirroring each point on the geometry of a certain line.
The original figure is called the pre-image and the final figure is called the image
The image will be congruent with the pre image and the distance of the image to the mirror axis is the same as the distance of the pre image to the mirror axis
There are several reflection equations:
- The equation of reflection across the<em><u> x-axis
</u></em>
x '= x
y '= - y
can be written
- The equation of reflection across the <u><em>y-axis
</em></u>
x '= x
y '= -y
can be written
- The reflection equation across the line <u><em>y = -x
</em></u>
x '= - y
y '= - x
can be written
- The reflection equation across the line x = h
x '= 2h-x
y '= y
can be written
- The reflection equation across the line y = k
x '= x
y '= 2k-y
can be written
So the correct rule for reflection is:
rx-axis (x, y) → (x, –y)
ry-axis (x, y) → (–x, y)

That expression can be written as this:
7x - 6 2/3+ 3x - 4 3/4. When you add like terms:
10x - 11 5/12.
So the answer is:
10x-11 5/12
Answer:
it shod be B. 1/3
Step-by-step explanation:
The equation would be y = 3x + 15.
Since there is a flat rate of 15, that is your y-intercept. The $3 charge is variable and depends on the number of days, so that would represent your slope.
