I need help guys! Determine if the following relations represent y as a function of x.

Functions are relations that only have one output per input (or graphically passes the vertical line test). You can either go on Desmos and graph this or just look at my explanations below.

1) function, pretty much all polynomials will be a normal function

2) function. This is a rational function, meaning you'll have some weird gaps and lines going to infinity but it's still a function. It's formed by a polynomial divided by another polynomial.

3) function, looks like you can simplify this into a standard rational function.

4) relation, y with an even square root are never going to give you a single solution (due to the nature of a + or - answer; \sqrt{9} = +3 and -3)

Which Pairs are additive inverses?<br> a. 6,-(-6)<br> b. -7,7<br> c.-7,-7<br> d.7,7<br> e.6,-6
xz_007 [3.2K]

I was never sure of what the "additive inverse" is. 
So, just now, just for you, I went and looked it up.

The additive inverse of any number ' A ' is the number
that you need to ADD to A to get zero.  That's all !

So now, let's check out the choices:

a), 6, -(-6)

That second number, -(-6), is the same as +6 .
So the two numbers are the same.
Do you get zero when you add them up ?  No.

b). -7, 7
What do you get when you add -7 and 7 ?
You get zero.
So these ARE additive inverses.

c). -7, -7
What do you get when you add -7 to -7 ?
You get -14 .  That's not zero, so these
are NOT additive inverses.

d).  7, 7
What do you get when you add 7 to 7 ?
You get 14.  That's NOT zero, so these
are NOT additive inverses.

e).  6, -6
What do you get when you add 6 to -6 ?
You get zero.
So these ARE additive inverses.

What do we end up with from the list of choices:

a).,  c).,  and d). are NOT additive inverses.

b). and e). ARE additive inverses.

30 Points!!Need Help Please!!! Will give Brainliest!!!
mixer [17]

Since DC = 12, then EF also = 12.

Both AD and BC are indicated to be the same .

So AE = (24 - 12) / 2 = 12/2 = 6


Now you have a right triangle with height DE = 8 and base AE = 6


Using the Pythagorean Theorem we can now find AD:


AD = √(8^2 + 6^2)

AD = √(64 + 36)

AD =√100

AD = 10
