Answer:

20.8

Step-by-step explanation:

The first step you need to do is to subtract 11:

52.6 - 11 = 41.6

The second step is to divide it by 2:

41.6 / 2 = 20.8

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 :)

The function f(x) varies inversely with x and f(x)=-15 when x=30
meriva
F(x) is the function that represents a given equation. It is defined more specifically by rules or conditions to satisfy the whole formula/equation.

In this case, f(x) has an inverse proportion with x (e.g. f(x) = 1/x). The second parameter says that f(x) = -15 when x is 30. Given that condition, just look for the formula, among the choices, that will result to -15 when x = 30. The answer is:

D. f(x) = -450/x

This is just -450/30 = -15
