Answer:

Step-by-step explanation:

Let f(x)=y

y=2x-10

Switch x and y,

x=2y-10

x+10=2y

(x/2)+5=y

So f^{-1}(x)=\frac{x}{2}+5

How do you use equivalent fractions to compare the fractions in each pair
Alenkasestr [34]
Firstly you need to to reduce to a common denominator by multiplYing the whole fraction. This way you have to multiply 4/5 by 2 (both numerator and denominator). so 4/5 = 8/10. And now you have 8/10 and 9/10. You compare only numerators. This way you have 8/10 <9/10. Same goes for 2/3 and 5/8. Only here you need to multiply both fractions. The common denominator here is 24. So you have to multiply 2/3 by 8 and 5/8 by 3. You now have to compare 16/24 and 15/24. 16/24>15/24.

Which is the correct answer
VashaNatasha [74]

Let s denote the number of pages in each issue of the sports magazine.

Let t denote the number of pages in each issue of the technology magazine.

Given that a sports magazine prints 12 issues per year and a technology magazine prints 10 issues per year.The total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year.

This can be written in equation as,

12s=10t+32

Since, it is given that, "Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine".

This can be written in equation as,

s=t-18

Thus, the set of equations that represent the given data is

12s=10t+32 and s=t-18

Hence, Option A is the correct answer.
