To find the inverse you have steps
1. replace f(x) with y
2. swich x and y places
3. solve for y
4. replace y with f⁻¹(x) (read 'f inverse')
so we have
f(x)=2x+1
replace f(x) with y
y=2x+1
switch x and y
x=2y+1
solve for y
x=2y+1
subtract 1
x-1=2y
divide both sides by 2

=y
y=

repplace y with f⁻¹(x)
f⁻¹(x)=
Answer:1695.75
Step-by-step explanation:
We know that there are 7 days in a week. Since 57 people rent skates each day, we know that 57*7=399 skates are rented each week. Since one skate cost 4.25, we know that 399*4.25 is the cost, which is 1695.75. (If you are not allowed to use a calculator, you can do 400*4.25-4.25, to make it easier to compute)
75%
30/40 means its 75% out of 100%
75$ representing the 30 and the 100$ representing the 40
Hey there!
Vick had 7/10 bucket of water. . . .
She used some of the water and now has 3/10 left . . .
Subtracts the numbers 7 and 3 to solve this:
7 - 3 = 4 <----
The correct answer to your question should be 4/10 of a bucket.
Vick used 4/10 of the bucket to wash the car.
Hope this helps you.
Have a great day!
the last two ones be the same, the outcomes would be TTT,HTT,THH,HHH
so the probability is 4/8 = 1/2.
