Please give brainliest please and good luck :)
Answer:
5
Step-by-step explanation:
We have been given that the point
lies on the curve
. Q is the point
. We are asked to find the slope of the secant line
for
.
Let us find y-coordinate corresponding to
for point P as:

Now, we will use slope formula to find required slope.
Let point
and point
.
Using these points in slope formula, we will get:

Therefore, the slope of the line PQ is 5.
Remark
You already know the slope. It is given as ( 5/3) so fiar you have
y = (5/3) x + b
Solution
Use the point (0,3) for your y intercept.
y = 5/3 x + b
3 = 5/3 * 0 + b
3 = b
y = 5/3x + 3 <<<<< Answer
Ax - By = c
Add By to both sides:
Ax = c + By
Divide both sides by A:
X = c + By / A or x = By + c / A
Answer:
The average rate of change is = - 4
Step-by-step explanation:
If y = f(x) is a function then the average rate of change for f(x) between the interval a ≤ x ≤ b is given by
.
Now, in this case the function is given by f(x) = - 4x + 40 and the interval is 1 ≤ x ≤ 3.
Therefore, f(1) = - 4(1) + 40 = 36 and f(3) = - 4(3) + 40 = 28
So, the average rate of change is =
