Answer:
The coordinates of the point S = (12, -22)
Step-by-step explanation:
The coordinate points of T = (0,6)
Mid point of ST = (6,-8)
Let the coordinates of S = (a,b)
Now, BY MID POINT FORMULA:
If (x, y) and (z, w) are the line point joining line segment and (p,q) is the coordinate of mid point. Then
So, here similarly,
⇒
⇒ a =2 x 6 = 12, b = 2 (-8) -6 = -22
⇒(a,b) = (12, -22)
Hence, the coordinates of the point S = (12, -22)
Answer:
Step-by-step explanation:
Given
Required
The average rate over
Average rate (m) is calculated using:
Where
So, we have:
Calculate f(b) and f(2)
So, we have:
Expand the numerator
Factorize
Factor out 3b + 6
Cancel out b - 2
