Answer:

Step-by-step explanation:

(x, y) -----> (x + 4, y - 1)

Adding 4 to the x means you move right 4. Subtracting 1 from the y means you move down one.

The next transformation (-(x + 4), y - 1)

If you look at the x coordinate and the transformation that is being applied

(-(x+4) that negative means you are taking the opposite of the x coordinate.

When you take the opposite of the x coordinate, it means you reflect it over the y axis.

A retangular prism has a length of 20 in. a width of 2 in., and a height of 3 1/4 in. The prism is filled with cubes that have e

ira [324]

Answer: 8320 cubes.

Step-by-step explanation:

1. Calculate the volume of the rectangular prism:

$V_1=l*w*h$

Where l is the lenght, w is the width and h is the height.

Substitute values.

(You can convert 3 1/4 to decimal by dividing the numerator by the denominator of the fraction and add this to the whole part: 3+0.25=3.25)

Then:

$V_1=20in*2in*3.25in=130in^{3}$

2. Calculate the volume of a cube:

$V_2=s^{3}$

Where s is the lenght of any side.

Then:

$V_2=(\frac{1}{4}in)^{3}=\frac{1}{64}in^{3}=0.0156in^{3}$

3. To calculate the number of cubes that are needed to fill the rectangular prism (which you can call n) , you must divide the volume of the prism by the volume of a cube. Then:

$n=\frac{V_1}{V_2}=\frac{130in^{3}}{0.0156in^{3}}=8320$ cubes

Which expressions are equivalent to the given expression. y^-8y^3x^0x^-2

vesna_86 [32]

$y^{-8} y^3 x^0 x^{-2}$ is equivalent to $y ^{-5} x ^{-2}\\$ .

<h3>What is a simplification of an expression?</h3>

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

Given;

$y^{-8} y^3 x^0 x^{-2}$

Simplify

$y^{-8} y^3 x^0 x^{-2}\\\\y ^{-8+3} x ^{0-2}\\ \\y ^{-5} x ^{-2}\\$

Hence, $y^{-8} y^3 x^0 x^{-2}$ is equivalent to $y ^{-5} x ^{-2}\\$ .
