The linear function f(x) = 0.2x + 79 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 86
2 84
3 82

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 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)

Given: The linear function f(x) = 0.2x + 79 represents the average test score in 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        1      2    3

g(x)   86  84   82

To Find : test average for math class after completing test 2

test average for science class after completing test 2

Which class had a higher average after completing test

Solution:

f(x) = 0.2x + 79

=> f(2) = 0.2(2) + 79 = 79.4

test average for math class after completing test 2 = 79.4

f(x) = 0.2x + 79

=> f(4) = 0.2(4) + 79 = 79.8

test average for math class after completing test 4 = 79.8

x        1      2    3   4

g(x)   86  84   82  80

g(2) = 84

test average for science class after completing test 2 = 84

g(4) = 80

test average for science class after completing test 4 = 80

80 > 79.8

science class has more average than math after 4 test

sorry its sloppy I didn't have much time

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
