Answer:
C.
The slope means that for every three rides, Brittany uses about 14 tickets.
Step-by-step explanation:
The given line of best-fit is
y = -4.64x + 47.6
Y-intercept is the point where x is zero. For the given equation y-intercept will be 47.6 or 48 rounded to nearest dollar. In other words, y-intercept is also a point where the line cross the y-axis.
From the given graph we can see that the y-axis shows the number of tickets purchased. The point where the line cross y-axis is about 48.
This tells us that Brittany had 48 tickets when she did not take any ride.
In this case, the slope of the line tells us that how many tickets were used for one ride, as x represents the number of rides. For one ride 4.64 tickets were, for 2 rides 2 x 4.64 = 9.28 tickets were used, for 3 rides 13.92 or around 14 tickets were used.
Now if we look at the given options we can easily say the option C is the correct answer.
Option A is not correct as it gives the opposite information than the actual one. Option B is also wrong, as x-intercept will tell us after how many rides the tickets will expire. Option D is wrong as y-intercept gives the number of tickets not the amount of money.
Answer: so to give a hint the graph is not porportional bc it does not run through the orgin so there for the equation you have to look at the first dot describe that write down the points and see how far apart they are by dividing them

hope this helps and plz brainliest ( if you wanna of course )
Alright, first thing's first, simplify the equation as much as you can. If you wanted, I suppose you could just multiply everything by 40, but that's super unconventional.
7x/8 - 3x/8 = 1/5 + 3/10
Simplify:
4x/8 = 1/5 + 3/10
Make sure that when subtracting or adding fractions that the denominators (The number on the bottom of the fraction) are equal.
In order to add 1/5 and 3/10 together, all we have to do is ensure that both denominators are equal.
To do this, simply multiply 1/5 by 2/2. The new fraction will be 2/10 (You can do this since it's the exact same fraction, 2/10 will simplify down to 1/5. The reason we did this was to make sure that the two fractions had equal denominators).
Our equation now looks like this:
4x/8 = 2/10 + 3/10
Add the fractions on the right:
4x/8 = 5/10
Huh, whaddya know? Both the fraction on the left and the right can be simplified into 1/2! (4/8 becomes 1/2, and 5/10 becomes 1/2)
1x/2 = 1/2
x/2 = 1/2
If you want to, I suppose you could cross multiply to check, but the answer's already pretty obvious.
x = 1
Good luck! If you need me to explain anything I did here, just ask :))

The equation that best represent the volume of the cylinder in cubic inches is V = π4²h.
<h3>What is a cylinder?</h3>
A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi.
Given that;
- Diameter d = 8in
- Radius r = d/2 = 8in/2 = 4in
- Height = h
- Volume of the cylinder V = ?
V = π × r² × h
V = π × (4)² × h
V = π4²h
Therefore, the equation that best represent the volume of the cylinder in cubic inches is V = π4²h.

<u>Answer:</u>
$14
<u>Step-by-step explanation:</u>
Assuming the cost of folder to be 
, then the cost of notebook will be 
and the cost of set of pencils will be 
.
Cost of the folder = $2
Cost of notebook = 4 × 2 = $8
Cost of pencil = 2 × 2 = $4
Total cost of 1 folder, 1 notebook and 1 set of pencils = $2 + $8 + $4 = $14
