Answer:

y = -2x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Points: (3, 4)

Slope: -2

y = -2x + b

4 = -2 ( 3 ) + b

4 = -6 + b

b = -2

y = -2x - 2

Answer:

y = -2x + 10

Step-by-step explanation:

To find the equation y=mx+b

The slope is already given so plug it in

y = -2x + b

Then your given a point so plug that into the equation to find b

y=4

x=3

4 = -2(3) + b

4 = -6 + b

+6 +6

10 = b

then plug everything in and your equation is y = -2x + 10

Given: ∆ABC –iso. ∆, m∠BAC = 120°

lidiya [134]

Answer: $P\triangle ADH = (a+b+\sqrt{a^2+b^2} )$ unit

Step-by-step explanation:

Since Here Δ ABC is a isosceles triangle.

Also, $AH\perp BC$ and $HD\perp AC$

Thus, ∠ ADH = 90°

That is, Δ ADH is the right angle triangle.

In which, AD = a unit and HD = b unit

And, By the definition of Pythagoras theorem,

$AH^2 = HD^2 + AD^2$

⇒ $AH^2 = a^2 +b^2$

⇒ $AH = \sqrt{a^2+b^2}$

Since, the perimeter of a triangle = sum of the all sides of the triangle.

Therefore, perimeter of ΔADH = AD + DH + AH

= $a + b + \sqrt{a^2+b^2}$ unit

How do you simplify a radical?

lys-0071 [83]

Answer:

$\huge\boxed{\texttt{See Explanation}}$

Step-by-step explanation:

In order to simplify a radical, we're looking for a perfect square within that number.

Say we have $\sqrt{108}$ .

We're looking for two numbers, where

1. We can easily find the square root of the first number

2. When we multiply that number by the second, we get 108.

We can experiment with numbers for 108. We know that $36 \cdot 3 = 108$ , so we can form this statement now.

$\sqrt{108} = \sqrt{36 \cdot 3}$

<em>We know the square root of 36 is 6</em>. Therefore, we can put this outside the square root sign and leave 3 inside.

$\sqrt{36} = 6\\6\sqrt{3}$

Hope this helped!
