Answer:

x and y do not show direct variation.  

Step-by-step explanation:

The formula for direct variation is

y = kx     Divide each side by y

k = y/x

k should have the same value for every point except, of course, (0,0)

For the first point,

k = 2/(-1) = -2

For the third point,

k = 2/1 = 2

The values of k are different, so x and y <em>do not</em> show direct variation.

Can an absolute value function have an inverse function? If so, give an
Musya8 [376]

Answer:

Let f be a function. If any horizontal line intersects the graph of f more than once, then f does not have an inverse. An absolute value function (without domain restriction) has an inverse that is NOT a function. That's why an absolute value function does not have an inverse function。

What is the solution to this equation y=4x<br> (1,3)<br> (-1,-4)<br> (-4,-1)<br> (1,-4)<br> !ASAP!
RideAnS [48]
(-1,-4) this is saying that when x=-1, y=-4. Plugging it into the line equation y=4x gives
(- 4) = 4( - 1)
Which is correct.

For the following exercises, solve each inequality and write the solution in interval notation.
WARRIOR [948]

Answer:

The solution to the inequality |x-2|>10 in interval notation is given by -8<x<12

Step-by-step explanation:

An absolute value inequality |x-2|>10 is given.

It is required to solve the inequality and write the solution in interval form.

To write the solution, first solve the given absolute value inequality algebraically and then write it in interval notation.

Step 1 of 2

The given absolute value inequality is $|x-2|>10$.

The inequality can be written as

x-2<10 and x-2>-10

First solve the inequality, x-2<10.

Add 2 on both sides,

x-2<10

x-2+2<10+2

x<12

Step 2 of 2

Solve the inequality x-2>-10.

Add 2 on both sides,

x-2>-10

x-2+2>-10+2

x>-8

The solution of the inequality in interval notation is given by -8<x<12.
