Given:
Consider the below figure attached with this question.
To find:
The value of
.
Solution:
The given functions are:


Now,




We know that,

Adding 3 on both sides, we get


So,
for all values of x.
Hence, the correct option is A.
77 percent of 149 is 114.73
There are 1130 females. There are 1370 males. What I did was take 2500 and subtracted 240 from it. I got 2260 and then divided that number by 2 and got the number of females. Then I took that number and added 240 to it and got the number of males.

Add 4 to both sides.
3/2x = 20
Multiply by 2/3.
x = 13 1/3
