Answer:
The answer is

Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ↶

❃Since we already have the slope, we don't need to solve for that.
➊ First: We are going to find the y-intercept.

➋Second: Plug in.

Partial products is breaking down every number in multiplication and adding them. Regrouping is grouping number them adding them. They are different because one is taking all the numbers broken down, while the other is just a couple of the number.
42,000 split into 10 is 4,200
if you meant 4 of those then it would be 16,800
<span>Ok, so we need to find the unit rate of 15 degrees in
2 hours.
this is a very simple question, it says here that in 2 hours, there are 15
degrees.
Thus we need to find the unit rate of
this given situation per hours.
=> hour many hours are there? The answer
is 2
so let us divide 2 by 15 to get the unit rate of the given situation
=> 15 degrees / 2 hours
=> 7.5 degrees / hours
Thus, the unit rate of 15 degrees per 2 hours is 7.5 degrees per hour.</span>
