Please help me im only looking for real answers

Answer: y=3/2x

Step-by-step explanation:

First, to find the equation, we can figure out that the cost depends on how many tickets are bought. We can use cost as our y and # of tickets as our x.

An equation in slope intercept form is as follows:

y=mx+b

To get our slope, we must figure out the relationship between the cost and the number of tickets, or the y and the x.

We can use the slope formula, \frac{y2-y1}{x2-x1}, to find the slope, m.

\frac{3-6}{2-4} = \frac{3}{2}

Thus, the slope of the equation is 3/2, making our final equation be y=3/2x.

The perimeter of a rectangular playground is 86 feet, the width of the playground is 15 feet, what is the length
Gennadij [26K]
The length is 28ft. W=15 so you’d subtract 30 from 86 and get 56. Then divide 56 by 2 and get 28 which is the length. You can check this by adding 15+15+28+27 together and see if it equals 86 which it does.
