I need it ASAP for 20 points and brainliest

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 47 Show work to support your answer. (6 points)

x g(x)

Step-by-step explanation:

Linear functions are very much like linear equations, the only difference is you are using function notation "f(x)" instead of "y". Otherwise, the process is the same. We are going to find the value of x when given a value for f(x). This is one of the trickier problems in the function unit. Watch carefully where we substitute the given number.

I hope this helped : )

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
