Let's solve the next equation:
We need to find the value for c, this value is correct when we replaced it with a number and the equality equation becomes true.
First, subtract both sides by 6
Now, subtract both sides by 8
Replacing the c value to verify:
The c value is correct.
<h2>Answer:</h2>
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
