Answer:
D. 8
Step-by-step explanation:
y varies jointly as x and z
y = k(xz)
-------------------------
Find k, the constant of variation
y = 12 when x = -2 and z=3
12 = k(-2 * 3)
12 = k(-6)
k = -2
-------------------------
find y when x is 4 and z is -1
using k = -2
y = -2(4 * -1)
y = -2(-4)
y = 8

The solution of the first graph is 1, 2 while the second graph is a straight line.
<h3>How to solve for the graph</h3>
We have y > 2x
y< x
First you have to replace the inequality by a mathematical operator
y - 2x = 0
y - 3 = 0
equation 1 is of the form
y = mx
The slope here is 2,
to make a graph we need to have x = 1 then the line would pass through
(1,2).
The second equation is simply a second line that would pass through the x axis.
The correct graph is below:

I think the question was partially cut off, but I think the question was "Simplify (3x)^-1".
The answer to that is 1/3x, which is (B).
