Can you take a better pic i cant see the whole problem
<span>The given function is f(x) = (7x + 1)/2. Write it as y = (7x)/2 + 1/2. To determine the inverse do these 3 steps. Step 1: Swap x and y to obtain x = (7y)/2 + 1/2. Step2: Solve for y. First, multiply through by 2 to obtain 2x = 7y + 1. Second, subtract 1 from each side to ontain 2x - 1 = 7y. Third, divide through by 7 to obtain (2x - 1)/7 = y. Step 3: Set y to the inverse of f(x) to obtain f^(-1) (x) = (2x - 1)/7.</span>
Answer:
of right angle triangle! .
Step-by-step explanation:
Here we have , A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 32 centimeters, and the length of the other leg is 25 centimeters. The student incorrectly says that the length of the hypotenuse is 7.5 centimeters. We need to find:
A)
We have , One length as 32 cm and other as 25 cm , as
By Pythagoras Theorem ,
⇒
⇒
⇒
⇒
So , of right angle triangle! .
hypotenuse = 41.2

Answer:
It will take Kali 40 years to get his balance to $3,000.
Step-by-step explanation:
5% intrest of 1,000 is 50, that is the amount of money that he will get per year.
If you subtract 1,000 off of 3,000 it is 2,000, that is the money needed to get to 3,000 dollars on his bank account.
Kali gets $50 a year, and he needs $2,000 to get to $3,000.
If you divide 2,000 by 50, you will get 40. This is the amount of years needed to get his bank account up to $3,000 without further investments.
