He drinks 8 glasses of water in one day. to know the number of glasses he drinks in 365 days, simply use cross multiplication as follows:
number of glasses per year = (365*8)/1 = 2920 glasses
so, yes his assumption is reasonable if he kept the same rate (8 glasses per day each day)

Find g^−1 (x) when g(x) = 3/5 x −9. 5/3x − 1/9 5/3 x + 9 −3/5 x+ 9 5/3 x + 15

Cerrena [4.2K]

Answer:

5/3 x + 15

Step-by-step explanation:

The inverse of a function is the reflection across the line y = x. As such, algebraically it is found by switching y and x in the equation and isolating to solve for y.

g(x) = 3/5 x - 9

x = 3/5 y - 9

x + 9 = 3/5 y

5(x+9) = 3y

(5x + 45)/3 = y

5/3x + 15 = y

What is the slope of the line passing through the points (-3, 4) and (2, - 1)?

dimaraw [331]

Answer:

slope = -1 or -x

Step-by-step explanation:

Do y2-y1/x2-x1

Plug in

-1 - 4/ 2 - -3 = -5/5

(Simplify)

-1 so the slope is

-1 or -x

If you want to find the equation use one of the points you have.

4 = -1(-3) + b

4 = 3 + b (subtract 3 on each side)

1 = b

y = -1x + 1 is the equation

Find the average rate of change for the function over the given interval.

jekas [21]

Answer:

The average rate of change for the function over the given integral

$A(x) = \frac{e^{-2} -1}{2}$

Step-by-step explanation:

Explanation

Average rate of a function:-

We can define the average rate of change of a function from a to b

$A(x) = \frac{f(b)-f(a)}{b-a}$

Given function f(x) = eˣ

Given interval x = a = -2 and y = b = 0

f(a) = f(-2) = e⁻²

f(b) = f(0) = e⁰

$A(x) = \frac{e^{-2} -1}{0-(-2)}$

The average rate of change for the function over the given integral
