f(x) + n - move the graph n units up

f(x) - n - move the graph n units down

n · f(x) - stretch by n in the y-direction

1/n · f(x) - compress by n in the y-direction

What are these fractions in simplest form?

Anton [14]

$\frac{16y^{3}}{20y^{4}} = \frac{4}{5y}$
$\frac{6xy}{16y} = \frac{3x}{8}$
$\frac{abc}{10abc} = \frac{1}{10}$
$\frac{mn^{2}}{pm^{5}n} = \frac{n}{pm^{4}}$
$\frac{12h^{3}k}{16h^{2}k^{2}} = \frac{3h}{4k}$
$\frac{8x}{10y} = \frac{4x}{5y}$
$\frac{24n^{2}}{28n} = \frac{6n}{7}$
$\frac{30hxy}{54kxy} = \frac{5h}{9k}$
$\frac{5jh}{15jh^{3}} = \frac{1}{3h^{2}}$
$\frac{20s^{2}t^{3}}{16st^{5}} = \frac{5s}{4t^{2}}$

Find the difference quotient <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bf%28x%20%2B%20h%29%20-%20f%28x%29%7D%7Bh%7D" id="TexFor

Answer:

$-2x - h - 3$

Step-by-step explanation:

Step 1: Define

Difference Quotient: $\frac{f(x+h)-f(x)}{h}$

f(x) = -x² - 3x + 1

f(x + h) means that x = (x + h)

f(x) is just the normal function

Step 2: Find difference quotient

Substitute: $\frac{[-(x+h)^2-3(x+h)+1]-(-x^2-3x+1)}{h}$
Expand and Distribute: $\frac{[-(x^2+2hx+h^2)-3x-3h+1]+x^2+3x-1}{h}$
Distribute: $\frac{-x^2-2hx-h^2-3x-3h+1+x^2+3x-1}{h}$
Combine like terms: $\frac{-2hx-h^2-3h}{h}$
Factor out h: $\frac{h(-2x-h-3)}{h}$
Simplify: $-2x - h - 3$

How many 3cm cubes can be put in a box 3cm long 6cm wide 12cm high?

lisov135 [29]

Answer:

Step-by-step explanation:

A cube is equal on all sides. Therefore the cubes must be 3cm x 3cm x 3cm. Therefore, each cube has an area of 27cm^3. The box that the cube has an area in is 3cm x 6cm x 12 cm which = 216cm^3. If you do $216cm^3/27cm^3 = 8 cubes$
