Y = mx + n

m = Slope

To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1

y = 2x + 5
ma = 2

D: y = -1/2x + 5
mb = -1/2

ma x mb = -1

2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1

It's true.

Answer: D.

I'm a bit confused with simplifying a squared fraction. Can you explain to me how I do it?

Margaret [11]

Answer:

$\frac{\sqrt{6} }{3}$

Step-by-step explanation:

$\sqrt{\frac{2}{3} }$

$\frac{\sqrt{2} }{\sqrt{3} }$

Multiply by $\frac{\sqrt{3} }{\sqrt{3} }$ to simplify

$\frac{\sqrt{2} }{\sqrt{3} }$ * $\frac{\sqrt{3} }{\sqrt{3} }$

$\sqrt{2} *\sqrt{3} =\sqrt{6}$

$\sqrt{3} *\sqrt{3} =3$

Therefore, the final answer would be:

$\frac{\sqrt{6} }{3}$

Thepotemich [5.8K]

Answer:

Consequently, any trigonometric identity can be written in many ways. To verify the trigonometric identities, we usually start with the more complicated side of the equation and essentially rewrite the expression until it has been transformed into the same expression as the other side of the equation.
