To change a decimal to a fraction, we simply "use as many zeros as there are decimals and lose the dot".

say in this case, 0.8 has 1 decimal, so we'll use one zero at the bottom,

$\bf 0.\underline{8}\implies \cfrac{08}{1\underline{0}}\implies \cfrac{8}{10}\qquad \stackrel{simplified}{\implies }\qquad \cfrac{4}{5}$

Which Product will result in a cell or difference of cubes? Pls do not give any joke answers

Rom4ik [11]

Answer:

(x-9)(x²+9x+81); it'll give a difference of cubes

Step-by-step explanation:

Generally, the difference of cubes formula is (a³-b³)=(a-b)(a²+ab+b²), and the third option is the only one which fits it; with "a"= x and "b"= 9.

*The sum of cubes formula is (a³+b³)=(a+b)(a²-ab+b²); for future reference.

Answer:

The graph is shown in the following image

Step-by-step explanation:

The parent function of $f(x) = | x + 1 | +2$ is $y = | x |$

The graph of $y = | x |$ is the union of two lines:

$y = x$ for $x\geq0$

$y = -x$ for $x$

The vertex of this graph is in point (0,0)

The graphic is shown in the attached image.

Then, if we do $y = f(x + 1)$ to the parent function we get:

$y = | x + 1 |$

This transformation shifts the graph of $y = |x|$ 1 unit to the left

Then, if we make the transformation $y = f(x) + 2$ to the function $y = | x + 1 |$ we obtain:

$y = | x + 1 | +2$

This transformation displaces the graph of the function $y = | x + 1 |$ 2 units up on the y axis.

So, if the vertex of the main function $y = | x |$ was at point (0,0), the vertex of the function $f(x) = |x + 1| +2$ has its vertex in the point (-1, 2).

The graph is shown in the following image
