Answer:
line FG
Step-by-step Explanation:
In the diagram, line CD passes through
The slope of this line is found using the formula,
We substitute the values to get,
So line CD is the line with slope
From the graph we can see clearly that, the only line that is perpendicular to CD is line FG.
Line FG also passes through
We can verify that the product of these two slopes is negative 1.
Therefore the correct answer is C
Answer:
Step-by-step explanation:
The inverse of the function x^7 is x^-7 and it is also a function.
An inverse function or an anti function is defined as a function, which can reverse into another function.
A standard method to find inverse of a function is to set y=f(x)
let y= f(x)=x^7
thus
![\sqrt[7]{y}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7By%7D)
=x
thus 
(y)=
thus ![f^{-1} (x)=\sqrt[7]{x}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%28x%29%3D%5Csqrt%5B7%5D%7Bx%7D)
(To verify this if a function is inverse or not we are required to check for the identity)
f((x))=(f(x))=x
Therefore, The inverse of the function x^7 is x^-7 and it is also a function.

Answer=0.5 hours
0.5 1
_____ =_____
0.25hr x hr
cross multiply
0.5x=0.25
divide both sides by 0.5
x=0.5 hr
It will take 0.5 hours to paint one wall
Answer:
Option B. 5 hours
Step-by-step explanation:
The tennis club charges monthly fees = $50.00
and per hour charges of court time = $10.00
Lets assume you play number of hours in a month = x hr
So, per hour charges would be = $10x
Total payment = monthly charges + charges of played hours
$100.00 = $50.00 + 10x
10x = 100 - 50
10x = 50
x = 5
Option B. You used 5 hours court time.
