Answer:

X=9

Step-by-step explanation:

So first you’ll get the variable on one side so you subtract 2x to x getting -x. That leaves you with 6=-x+15. Then you want to subtract 15 from 6 to get the variable alone. This makes -9=-x then you remove the subtraction symbols because they’re on both sides and if you divide x by -1 and -9 by -1 you get x=9 anyways. So that’s you’re answer x=9.

Answer:

Step-by-step explanation:

Exponent law:

$\sf \bf a^m * a^n = a^{m+n}\\\\ (a^m)^n = a^{m*n}$

$\sf a^{-m}=\dfrac{1}{a^m}$

First convert radical form to exponent form and then apply exponent law.

$\sf \sqrt{3}=3^{\frac{1}{2}}\\\\\sqrt{5}=5^{\frac{1}{2}}$

$\sf \left(\dfrac{(\sqrt{3}*3^{-2}}{(\sqrt{5})^2}\right)^{\frac{1}{2}}= \left(\dfrac{3^{\frac{1}{2}}*3^{-2}}{(5^{\frac{1}{2}})^2} \right )^{\frac{1}{2}}$

$= \left(\dfrac{3^{\frac{1}{2}-2}}{5^{\frac{1}{2}*2}}\right)^{\frac{1}{2}}\\\\=\left(\dfrac{3^{\frac{1-4}{2}}}{5}\right)^{\frac{1}{2}}\\\\=\left(\dfrac{3^{\frac{-3}{2}}}{5}\right)^{\frac{1}{2}}\\\\=\dfrac{3^{\frac{-3}{2}*{\frac{1}{2}}}}{5^{\frac{1}{2}}}\\\\ =\dfrac{3^{{\frac{-3}{4}}}}{5^{\frac{1}{2}}}$

9. Which lines are parallel if m<4 = m<5? Justify your answer.

DIA [1.3K]

Answer:

lines r and s

Step-by-step explanation:

we know that

Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.

When the lines are parallel, the alternate interior angles are equal

In this problem

If lines r and s are parallel

then

m∠4=m∠5 ----> by alternate interior angles
