No I do not agree with (2,-4) I believe the solution is (-4,2)
Answer:
The 4th answer, at the bottom.
Step-by-step explanation:
The first answer is proportional, because y is equivalent to .5x.
The second answer is also proportional, because the ratios are equivalent.
The third answer is also proportional, because the line goes through the origin.
The fourth answer isn't proportional, because the ratios aren't equivalent.
Let's solve ~
Hence, the correct choice is D
Given:
The function is:
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
Step 1: Substitute 
.
Step 2: Interchange x and y.
Step 3: Isolate variable y.
Step 4: Substitute 
.
Therefore, the inverse of the given function is 
and the graphs of these functions are shown below.
Answer:
A 4/5 × 10 1/2 =8.4
B 2 1/2 × 16/5 =8
C 3 2/3 × 2 1/2 = 330/36 = 9.1666
D 20/3 × 9/10 =6
C IS THE GREATEST because 9.166 is greater than 8.4, 8 and 6
