2 PointsIf y(x) = x - 2, which of the following is the inverse of Ax)?
O . F'(x) = 2 - x
O B. f'(x) = x-2
O c. f'(x) = 2x
OD. F'(x) = x+2
Answers
Answer:
D
Step-by-step explanation:
let y = x - 2 and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
now change x to (x) and y back to x, thus
(x) = x + 2 → D

The three equivalent ratios are 27/6, 45/10, and 36/8.
Given,
The ratio of right-handed students to left-handed students is 18:4.
We need to find three equivalentratios of 18:4.
What is a ratio?
A ratio is denoted by A:B.
If the ratios are equal we called it proportion.
Example:
2/4 = 16/32 = 6/12
2/4 = 1/2
16/32 = 2/4 = 1/2
6/12 = 1/2
2/4, 16/32, and 6/12 are equivalent ratios and they are in proportion.
We have,
18:4
It can be written as:
= 18/4
Reducing it to the smallest term.
= 2 x 9 / 2 x 2
= 9 / 2
So,
We can have,
27/6, 45/10, and 36/8 as our equivalentratios.
27/6 = 3 x 9 / 3 x 2 = 9/2
45/10 = 5 x 9 / 5 x 2 = 9/2
36/8 = 4 x 9 / 4 x 2 = 9/2
Thus the three equivalent ratios are 27/6, 45/10, and 36/8.

9 : 2 if you divide 18 and 4 by 2
36 : 8 if you multiply 18 and 4 by 2
54 : 12 if you multiply 18 and 4 by 3
Hope this helps!!
