Find the inverse of the function f (x) = 0.25x + 12.

Mathematics
1 answer:
worty [1.4K]3 years ago
5 0

Answer:

g(x)=4x-48

Step-by-step explanation:

f(x)=0.25x + 12

substitute

f(x) with y

y=0.25x + 12

then replace x with y and y with x

x=0.25y + 12

swap equation

0.25y + 12 = x

0.25y = x - 12

divide both sides by 0.25

Y=4x-48

iogann1982 [59]

Answer:

y = 15x + 50

Step-by-step explanation:

We set out by finding the slope

the two points give are (15,275) and (25,425)

Slope m is;

y2-y1/x2-x1 = (425-275)/25-15 = 150/10 = 15

So the equation is like;

y = 15x + b

To get b, let us use the point (15,275)

We have

275 = 15(15) + b

b = 275-225

b = 50

So the equation is;

y = 15x + 50

eimsori [14]

Given:

Reese read twice as many pages Saturday than she read Sunday.

She read a total of 78 pages over the weekend.

To find:

The number of pages she read on Sunday.

Solution:

Let x be the number of pages she read on Sunday.

Reese read twice as many pages Saturday than she read Sunday. So, the number of pager she read on Saturday is 2x.

Total number of page she read over the weekend is:

Total=x+2x

Total=3x

She read a total of 78 pages over the weekend.

3x=78

x=\dfrac{78}{3}

x=26

Therefore, Reese read 26 pages on Sunday.

What is the average rate of change of the function f(x)=2x+4 over the interval -4 ≤ x ≤ 1? Table
Tom [10]

Answer:

2

Step-by-step explanation:

the rate of change is measured as

\frac{f(b) - f(a)}{b-a} in the closed interval [ a, b ]

here [a, b ] = [- 4, 1 ]

f(b) = f(1) = 2 + 4 = 6

f(a) = f(- 4) = - 8 + 4 = - 4

average rate of change = \frac{6-(-4)}{1-(-4)} = \frac{10}{5} = 2
