ikadub [295]3 years ago

Given function :-

\bf \implies g(x) = \dfrac{3}{x}+7

  • To find its reverse , substitute y = g(x) .

\bf \implies y = \dfrac{3}{x}+7

  • Interchange x and y .

\bf \implies x = \dfrac{3}{y}+7

  • Solve for y .

\bf\implies \dfrac{3}{y}= x -7 \\\\\bf\implies y =\dfrac{3}{x-7}

  • Replace y with f-¹(x) .

\implies\boxed{\red{\bf f^{-1}(x) = \dfrac{3}{x-7} }}

Answer:

The answer is -15.

Step-by-step explanation:

1. 2x - 1

2. 2(-7) - 1

3. (-14) - 1

4. -15

By plugging in our x value, we are able to use PEMDAS to  multiply 2 and the value of x and then, we subtract 1 from the value we got from step 3 to get -15.

Katie is twice as old as her sister Mara. The sum of their ages is 24. Find their ages.
Alenkasestr [34]
So k=katie's' age
m=mara's age

k is 2 times as old as m
k=2m

sum is 24
add means sum
k+m=24

so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16

katie=16
mara=8
