I will brainlist who can answer this 3 Questions!

20.) A

y = 10x + 15

21.) C

Php 75.00

22.) B

Php 195.00

Step-by-step explanation:

20.)

We see an increase of 10y per x, which is where we get "10x"

This means that at x = 1, y = 15, which is where we get "+ 15"

21.)

Plug in 6 for x

y = 10(6) + 15

y = 60 + 15

y = 75

Php 75.00

22.)

Plug in 18 for x

y = 10(18) + 15

y = 180 + 15

y = 195

Php 195

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

answer for #1 is c

answer for #2 is d
