There are 160 dolls in the store.
<u><em>Explanation</em></u>
The ratio of the number of teddy bears to the number of dolls is given as
Suppose, the number of teddy bears and the number of dolls
Given that, the store has 60 teddy bears. That means....
(Dividing both sides by 3)
So, the number of dolls in the store
The rate of change between the points (–3, 0) and (–2, –5) is:
-5
<h2>Step-by-step explanation:</h2>The rate of change between the points (-5, 10) and (-4, 5) is -5.
Now we are asked to find the average rate of change between (-3,0) and (-2,-5)
We know that the average rate of change between two points (a,b) and (c,d) is calculated by the formula:
Here we have:
(a,b)=(-3,0) and (c,d)=(-2,-5)
Hence, the average rate of change is:
Also, we know that for any linear function the average rate of change is same between any two points.
Hence, the answer is:
-5
