|x+4| = horizontal translation left 4 units
|x|+4 = vertical translation up 4 units
|x|-4 = vertical translation down 4 units
|x-4| = horizontal translation right 4 units

Think of it as when both x and a number are between the lines then do the opposite of what it says. For example |x+2| is actually going horizontal left 2 units so think of it as the plus being a minus. Same for |x-2| it is actually going horizontal right 2 units so think of it as adding 2 units

When it is just |x| plus or minus a number then you’re going up or down as in vertical so if it says for example: |x|+2 you’d be going vertical up 2 units and if it said |x|-2 then you’d be going vertical down 2 units.

Hope this helps!

the lateral area of a cone is 574 pi cm2. The radius is 19.6 cm. What is the slant height to the nearest tenth of a centimeter?

bulgar [2K]

$\bf \textit{lateral area of a cone}\\\\
LA=\pi r\sqrt{r^2+h^2}~~
\begin{cases}
r=radius\\
\sqrt{r^2+h^2}=slant~height\\
-----------\\
LA=574\pi \\
r=19.6
\end{cases}
\\\\\\
574\pi =\pi (19.6)\sqrt{r^2+h^2}\implies \cfrac{574\pi }{19.6\pi }=\sqrt{r^2+h^2}
\\\\\\
\cfrac{574}{19.6}=\sqrt{r^2+h^2}$

Choose the correct solution and graph for the inequality "-x/3<=6"

lina2011 [118]

Answer:

Step-by-step explanation:

To solve this inequality, we have to find x (or make x the subject of the inequality:

since ⁻ˣ/₃ ≤ 6 [multiply both sides by 3]

- x ≤ 18 [multiply both sides by -1; this flips the inequality sign]

<h3> x ≥ - 18 [this is the solution]</h3><h3 />

To graph the inequality, draw the line x = - 18 with a solid line, and then shade the region that is x > -18.

We use a solid line because the point x = -18 is included. However, hypothetically, if the inequality was x > -18 only, a broken line would be used to show that the line x = -18 is not included.
