Solving for systems of equations by substitution. <br><br> Y=4x <br> X+y=5

dolphi86 [110]

Since the first equation already gives you y, substitute Y for 4x in the second equation.
y=4x
x+y=5

x+(4x)=5
5x=5
x=1

Now that you know x, plug in x for 1 in the first equation.
y=4(1)
y=4
Answer: (1,4)

What is the following quotient? StartFraction 3 StartRoot 8 EndRoot Over 4 StartRoot 6 EndRoot EndFraction.

Snowcat [4.5K]

You can simplify the given expression by taking out those factors who are perfect squares.

The simplified form of the given expression will be $\dfrac{\sqrt{3}}{2}$

<h3>How to simplify values which are under the root?</h3>

If possible, try to defactor what is inside the root.

For example, if 8 is under square root, then you can defactor 8 as made up of 2 times 2 times 2. Since 2 times 2 is perfect square, thus this can come out of the root.

Simply, some more such methods can be used to simplify these type of values.

<h3>Using the simplification method on given expression</h3>

$\dfrac{3\sqrt{8}}{4\sqrt{6}} = \dfrac{3\sqrt{2 \times 2 \times 2}}{4\sqrt{6}}\\\\
\dfrac{3\sqrt{8}}{4\sqrt{6}} = \dfrac{3 \times 2\sqrt{2}}{4\sqrt{6}}\\

\\
\dfrac{3\sqrt{8}}{4\sqrt{6}} = \dfrac{6\sqrt{2}}{4\sqrt{6}} = \dfrac{\sqrt{6}\sqrt{2}}{4}\\\\
\dfrac{3\sqrt{8}}{4\sqrt{6}} = \dfrac{\sqrt{12}}{4} = \dfrac{\sqrt{4 \times 3}}{4} = \dfrac{\sqrt{3}}{2}$

Thus, after getting simplified, the expression becomes $\dfrac{\sqrt{3}}{2}$
