Anastasy [175]

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (5, - 8)

m = \frac{-8-1}{5-2} = \frac{-9}{3} = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 1) , then

1 = - 6 + c ⇒ c = 1 + 6 = 7

y = - 3x + 7 ← equation of line

Elena L [17]

Answer:

1)

12\sqrt{18}-3\sqrt{50}+\sqrt{32}

12\sqrt{9}\sqrt{2}-3\sqrt{25}   \sqrt{2} +\sqrt{16} \sqrt{2}

12\times3\sqrt{2} -3\times5\sqrt{2}+4\sqrt{2}

36\sqrt{2}-15\sqrt{2}+4\sqrt{2}

25\sqrt{2}

2)

\frac{1}{5+2\sqrt{6}}

Multiply 5-2\sqrt{6}:

\frac{1\times \left(5-2\sqrt{6}\right)}{\left(5+2\sqrt{6}\right)\left(5-2\sqrt{6}\right)}

Apply Difference of Squares formula: (a+b)(a-b)=a^2-b^2

\frac{5-2\sqrt{6}}{5^2-\left(2\sqrt{6}\right)^2}

\frac{5-2\sqrt{6}}{25-2^2\left(\sqrt{6}\right)^2}

\frac{5-2\sqrt{6}}{25-4\times6}

\frac{5-2\sqrt{6}}{1}

{5-2\sqrt{6}}

a = 5, b = -2
