For this case we must find the inverse of the following function:
We follow the steps below:
Replace f(x) with y:
We exchange the variables:
We solve for "y":
Multiply by -2 on both sides of the equation:
We raise both sides of the equation to the square to eliminate the radical:
We subtract 3 from both sides of the equation:
We change y by f ^ {- 1} (x):
Answer:
6. irrational because nothing times itself is 127.
7. a. 29 is the width plus two things that will equal 105 which would be two 52.2 lengths
b. 29, 52.2, 52.2 or 29, 29 69
8. a. 402 - 237(x/15)
b. 11
c. 12
9. no because it does not reach 90 when you add them together
10. rational because the decimal terminates
Answer:
10 and 11
Step-by-step explanation:
Let the first integer be x.
Then the next one, since it's consecutive, must be (x+1).
The two equals 21. Thus:
Combine like terms:
Subtract 1 from both sides:
Divide both sides by 2:
So, the first integer is 10.
And the second integer is 10+1=11.
Answer: I believe the answer is 6x.
Equation
Y=P%*X
Y= 25%*75
Converting percent to decimal:
p = 25%/100 = 0.25
Y = 0.25 * 75
Y = 18.75
