If you would like to solve the system of equations, you can calculate this using the following steps:

6x – 3y = 3
–2x + 6y = 14 /*3
_________
6x – 3y = 3
<span>–6x + 18y = 42
</span>_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3

<span>6x – 3y = 3
</span>6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2

(x, y) = (2, 3)

The correct result would be (2, 3).

Another expression for the given rational function is $x =r^\frac{1}{2}s^\frac{1}{2}$

<h3>Indices expression</h3>

Given the rational function expressed as:

x = √rs

We can reconstruct the expression by writing it using exponents as shown;

$x =\sqrt{rs}=(rs)^{\frac{1}{2} }$

Separate to have:

$x =r^\frac{1}{2}s^\frac{1}{2}$

Hence another expression for the given rational function is $x =r^\frac{1}{2}s^\frac{1}{2}$

What is the slope of a line that passes through (-4,-13) and (19,11)?

raketka [301]

We can find the slope from the two given points using the standard formula:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m=\frac{11-(-13)}{19-(-4)}$
$m=\frac{24}{23}$

A cube is cut in to three parts by vertical slices find the volume of the shaded area The length and width of original is 20 cm

Anni [7]

Answer:

4000 cm^3

Step-by-step explanation:

Note that no image was attached for reference purposes

Step one:

We are given that the original length and width of the cube is 20cm

if the cut part is 10cm

hence the dimension of the cut part is

lenght = 20cm

Width= 20cm

Hieght= 10cm

Step two:

the volume of the cut part will be

Volume= 20*20*10

Volume= 4000 cm^3
