HELP PLS!! 50 POINTS + I"LL REWARD BRAINLIEST

The linear function f(x) = 0.9x + 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 78
2 79
3 80

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

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

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

Part A.

f(x) = 80.8

Part B.

x = 79

Part C.

Math class > Science class

Step-by-step explanation:

Using the function,

f(x) = .9x + 79

[x] is the # (number) of tests taken for math class. And in the question for Part A. it is said after completing test 2, this could be implying that what would there avg. be after taking 2 (two) tests. So, subsitute 2 into [x]

f(x)  = .9(2) + 79

f(x) = 1.8 + 79

f(x) = 80.8 <- This is the avg. for the math class

Part B.

From the table provided, after taking two tests, th avg. was 79, this can also be verified form the fact that it is shown:

x | g(x)

1 | 78

2 | 79 <- This is the avg. for science class.

3 | 80

Part C.

The class with the higher acg after completing test 4 would be the math class, because if you used the functiona nd subsituted 4 into [x], you would get: 82.6

While for the graph the next # (number) would be

4 | 81

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
