Option (c)
Chuy will save more than he needs and will meet his goal in less than 27 week.
Step-by-step explanation:
Given that, Chuy wants to buy a new television. The television cost is $1,350.
He decides to save the same amount of money each week.
After 8 weeks he saved $440.
Each week he saved
=$ 55
If he saved $55 each week.
At the end of 27 week he will save = $(27×55)
=$1485
Therefore he will save $1485 at the end of 27th week.
The saved money is more than the cost price of the television.
Therefore Chuy will meet his goal in less than 27 weeks.
Answer:
Inverse of y = =
.
Step-by-step explanation:
Given : f(x) = y = 100 - x²
To find : Find inverse.
Solution : We have given that :
f(x) = y = 100 - x²
Step1) : Replace every x with a y and replace every y with an x .
x = 100 - y².
Step 2): Solve for y
On subtracting 100 from both sides
x - 100 = -y²
On multiplying both side by -1
100 -x = y²
Taking square root both sides and switching sides
y = ± .
Step3 ) : Replace y with .
= ±
.
Therefore, inverse of y = = ±
