Answer: Expression for the amount raised by Rachel = x
Expression for the amount raised by Francesca = x+10.50
Step-by-step explanation:
Let x = the amount raised by Kayla.
Since Rachel and Kayla each raised the same amount.
then, expression for the amount raised by Rachel = x
Francesca raised $10.50 more than each of them.
Then, expression for the amount raised by Francesca = x+10.50
A) July b/c 35k is the smallest number of change
and
b) May and August b/c 316k and 371k are both larger than 250 k
Answer:
-8
Explanation:
The instantaneous rate of change when x = 2 is equal to the slope of the tangent line at that point. So, we need to find the slope of the following line
Using two points (x1, y1) and (x2, y2) of the line, we can calculate the slope as follows
So, replacing (x1, y1) by (2, -8) and (x2, y2) by (1, 0), we get:
Therefore, the estimate of the instantaneous rate of change is -8.
To find the perimeter you add up all the sides.
8m+3m+8m+3m= 22meters
Perimeter: 22 meters
