Find the midpoint of the segment with endpoints of -2,-2 and 4,6
RideAnS [48]

Answer:

( 8 , 3 )

Step-by-step explanation:

Use the midpoint formula to find the midpoint of the line segment.

Midpoint formula is a mathematically equation used to measure the halfway point between two data points.

Calculating the midpoint is the same thing as calculating the average of two numbers. Therefore, you can calculate the midpoint between any two numbers by adding them together and dividing by two. For example, suppose you want to find the midpoint between the numbers 2 and 32. First, add the two numbers: 2 + 32 = 34.

I think don't get mad if its wrong :)

For the following exercises, evaluate the expressions, given functions f, g, and h:
sertanlavr [38]

Answer:

- 16

Step-by-step explanation:

Evaluate f(2) by substituting x = 2 into f(x) , that is

f(2) = 3(2) - 3 = 6 - 3 = 3

Evaluate g(- 1) by substituting x = - 1 into g(x) , that is

g(- 1) = 8 - (- 1)² = 8 - 1 = 7

Thus

4f(2) - 4g(- 1)

= 4(3) - 4(7)

= 12 - 28

= - 16
