21.9 is the answer so I hope you get it right

Answer with explanation:</h2>
The average rate of change for function f(x) over the interval a ≤ x ≤ b is given by :-

So, the rate of change for function
over the interval −3 ≤ x ≤ 4 :

The rate of change for function
over the interval −3 ≤ x ≤ 4 :

So, the rate of change for g(x) is greater than f(x) over the interval −3 ≤ x ≤ 4.
Hello,
f(x) = 1/9x + 2 ⇔ y = 1/9x + 2 ⇔ 1/9x = y - 2 ⇔ x = 9(y - 2)
x = 9y - 18
⇒ f⁻¹(x) = 9x - 18
Answer:

Answer:
70 standard boxes, 40 deluxe boxes
Step-by-step explanation:
standard: x
deluxe: y
x + y = 110
7x + 11y = 930
Multiply the first equation by 7 and subtract.
7x + 7y = 770
-(7x + 11y = 930)
You get -4y = -160
y = 40
Substitute y into the first equation.
x + 40 = 110
x = 70
