Question

What is the answer to 13+14?!?

Answer 1

The answer to #13 is C, that is the definition of a linear function. Rise/Run is the same as y-values/x-values, which is the slope. Linear functions have constant slope. This is the same thing as saying the ratios of the change in y-values to the change in x-values are equal.

For #14:

Let's find out how many people entered the park after 1 minute, then we can calculate for 30 minutes. In 2 minutes, 144 people entered the park.


`\sf 144/ 2=72`

So in 1 minute 72 people enter the park. This is our unit rate. To find out how many people enter the park in 30 minutes, multiply it by our unit rate.


`\sf 30* 72=\boxed{\sf 2160}`

So 2,160 people enter the park after 30 minutes.
