NEED ANSWER ASAP The linear function f(x) = 0.5x + 80 represents the average test score in your math class, where x is the number of the test taken. The linear function g(x) represents the average test score in your science class, where x is the number of the test taken.

x g(x)
1 81
2 83
3 85

Part A: Determine the test average for your math class after completing test 2. (2 points)

Part B: Determine the test average for your science class after the completing test 2. (2 points)

Part C: Which class had a higher average after completing test 4? Show work to support your answer. (6 points)

Science class had a higher average

Step-by-step explanation:

Given

g(x) table

Solving (a): f(2)

We have:

So:

Solving (b): g(2)

From the given table.

Solving (c): f(4) or g(4); which is greater

So:

For g(4): Notice that in the table of g(x); g(x) increases by 2 when x increases by 1

This means that:

So

Hence, g(4) i.e. Science class is greater

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
