Answer:

y = x/4

Step-by-step explanation:

First, replace f(x) with y, so it's easier to find the inverse:

y = 4x

To find the inverse of this function, you would replace all the y's with x's and all the x's with y's, and then solve for y. That would be:

x = 4y

y = x/4

Therefore, the inverse function of y = 4x is y = x/4.

Work out the value of six squared plus three cubed
IrinaK [193]

Answer:

63

Step-by-step explanation:

Based off of the question,we have a word problem that can be interpreted as the following. 6²+3³= ?

6² is the same as 6×6 which is equal to 36, In other words 6×6=36 or 6²=36

3³ is the same as 3×3×3 which is equal to 27, In other words 3×3×3=27 or

3³=27

Now with the product of each value in the word problem we can set up a statement as the following: 36+27= ?

Which when added together gives us the sum of 63, in other terms 36+27=63

concluding in our answer for the initial word problem. (6²+3³=63)

Use the work shown which expression is equivalent to
algol [13]

Answer:

\frac{1}{3} y - \frac{7}{5}x + \frac{2}{3} - \frac{2}{3} y - \frac{4}{9}

Step-by-step explanation:

We are to find the expression which is equivalent to;

-\frac{2}{3}y - \frac{3}{5} x + \frac{2}{9} - \frac{4}{5}x + \frac{1}{3}y

Putting the like terms together we get;

-\frac{2}{3}y + -\frac{2}{3}y - \frac{3}{5} x - \frac{4}{5}x + \frac{2}{9}

Simplifying this gives;

-\frac{1}{3}y - \frac{7}{5}x + \frac{2}{9}

The equation that is equivalent to this answer from the choices is;

\frac{1}{3} y - \frac{7}{5}x + \frac{2}{3} - \frac{2}{3}y - \frac{4}{9}
