Answer:

x = -12

Step-by-step explanation:

$\frac{-x}{2}$ can also be expressed as, $\frac{-1}{2} x$ . So all you need to do is, multiply both sides of the inequality by the reciprocal of the fraction, which is -2:

$\frac{-1}{2} x$ = 6

-2 · $\frac{-1}{2} x$ = 6 · -2

x = -12

Write inequalites to describe the region. The solid cylinder that lies on or below the z=8 and or above the disk in the xy-plane

Vladimir79 [104]

Answer:

x^2 + y^2 <= 4, 0 <= z <= 8

Step-by-step explanation:

Region that lies on/below the plane means Z<=8
Region that lies on/above the xy plane means Z>=0.

Combining 1 and 2, we get

0<=Z<=8

If we want disk of radius 2 in x-y plane to be centered at origin the inequality becomes:

x^2 + y^2 <= 4

Help please!!!<br><br> which graph represents the function f(x)=4/x?

Vedmedyk [2.9K]

Answer:

Not the graph you attached to your question

Step-by-step explanation:

For sure not the graph you attached to your question, since although the general features at infinity (when x grows in absolute value) and the vertical asymptote at x=0 are not that different from the only graph you show, there are some important details that tell you this is not the correct graph:

For example, the graph of the function f(x) = 4/x for sure should show a value of "1" (one) when x is 4 :

$f(4) = \frac{4}{4} = 1$

It should also give a value of "-1" (negative one) when x is -4.

$f(-4) = \frac{4}{-4} = -1$

This is NOT true in the graph you attached to this question.

Please see the appropriate graph you should be looking for in the image I am attaching to this answer. And notice the value you should be able to extract from the graph when x equals 4 for example.
