To divide by a fraction, multiply by the reciprocal of that fraction.
1/3 • 5/1 or 1/3 • 5
Calculate the product straight across.
1/3 • 5/1 = 5/3
Answer:
composite number
Step-by-step explanation:
x = 5
y = -1
Step-by-step explanation:
from second equation,
by putting the value of y in first equation
- y = -x + 4
- -1 = -x + 4
- -x = -1 -4
- -x = -5
- x = 5
x = 5 and y = -1
<u>Answer</u>:
![f^{-1}(x) = \sqrt[5]{\frac{x+7}{9} -10}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Csqrt%5B5%5D%7B%5Cfrac%7Bx%2B7%7D%7B9%7D%20-10%7D)
<u>Explanation</u>:
given : f(x) = 9( 
+ 10 ) - 7
replace x and y with each other.
- x = 9(
+ 10 ) - 7
solve for y
- x + 7 = 9( + 10 )
- =
- 10
- y =
![\sqrt[5]{\frac{x+7}{9} -10}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%5Cfrac%7Bx%2B7%7D%7B9%7D%20-10%7D)
Therefore,
760 ft would be the area of the floor :)
