Write a function to describe the following scenario. After sprinting, Emilie has a heart rate of 160. As
she cools down, her heart rate falls by 12 beats
per minute. What will her heart rate be after a
certain number of minutes?
y = [?] - [ ]2

Step-by-step explanation:

Heart rate will be represented by , minutes will be represented by .

Here's the equation I came up with:

We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.

This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.

I hope this helps!

the answer is ! ?

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
