\frac{2x^3a^3}{5x^{-3}a^2}\cdot\frac{5x^{-4}a}{3x^2a^{-5}}=\frac{2x^{3-4}a^{3+1}}{3x^{-3+2}a^{2-5}}=\frac{2x^{-1}a^4}{3x^{-1}a^{-3}}=\frac{2}{3}a^{4-(-3)}=\frac{2}{3}a^7

Compare your response to the sample response above. what did your explanation include? the conclusion that the work was incorrec
Alenkasestr [34]

In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.

<h3>What is the variables  about?</h3>

Note that:

y=-8x+4

y-4=-8x

(y-4)/-8=x

Since the independent variable x is known, one can switch the variable labels and thus it will be:

y=(x-4)/-8

f^-1(x)=(x-4)/-8    

This can be written again as:

f^-1(x)=(4-x)/8  :P

Thus one can say  No, as he forgot to switch the variable labels after solving for the independent variable.

In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.

See the first part of the question below

Talib is trying to find the inverse of the function to the right. His work appears beneath it. Is his work correct? Explain your answer.

Andy carried 1/2 gallon of water on a hike. He drank 2/3 of the water. How much water did he drink?
Contact [7]
So,

All we have to do is multiply the amount of water Andy carried by the fractional amount he drank.

1/2 * 2/3

This is pretty simple.  To halve TWO-thirds, just halve the numerator, since it's such a nice number.

Presto.  Half of two is one.

Therefore, 
1/2 * 2/3 = 1/3

Andy drank 1/3 gallons of water on his hike.  That's 5 1/3 cups of water.  I would estimate his hike to be about 3 miles.  Easy peasy.
