-3x-12> 8x + 21
+12 +12
-3x > 8x + 33
-8x -8x

-11x > 33

-11

x < -3

I moved the real numbers to one side and and the variable to the other side to solve for the inequality

I also remembered somewhere that if you divide by a negative number the inequality sign switches.

Hello!

We can go through the choices and see if they are true

Choice 1
A function has one output for every input

This is not a function because it has -1 as an output for both 4 and -1

This is the answer
------------------------------------------------------------------------------------------------------
Choice 2
The inputs are the x's

We see that the inputs are -1, 0, 3, and 4

This is true
------------------------------------------------------------------------------------------------------
Choice 3
The outputs are the y's

We see the outputs are -2, -1, and 1

This is true
------------------------------------------------------------------------------------------------------
Choice 4
We can follow the lines and see the relations are

(-1, 1), (0, -2), (3, 1), (4, -1)

This is also true
------------------------------------------------------------------------------------------------------
The only one that was false was the first choice so that is the answer

The answer is A) The diagram represents a function

Hope this helps!

Look at the face of the pyramid facing you.  The length of the base of this pyramid is 82 m; half of that is 41 m.  

If you were to draw a straight vertical line through the vertex of the pyramid, the bottom of this line would be at the very center of the base and also be 41 in perpendicular distance from any of the edges of the base of this pyramid.

Let the height of the pyramid be y, as measured upward from the center of the base of the pyramid.  This center is, as before, 41 m from any side of the pyramid base, a horiz. distance.

Then, tan 52 deg = y / 41 m, and so y = height of pyramid =

(41 m)(tan 52 deg)  = (41 m) (1.28) = 52.48 m
