Crank

Answer: The stuff in pink is the stuff I found based on the information given. The pink 40 comes from the blue 40. The reason that both of those angles are congruent is because they are alternate interior angles. This is the same reason about the angles whose measurements are 60. So the following things are true that we found that weren't already given: Angle PQR is 40 Angle PRQ is 60

A line passes through the point (-2, 6) and has a slope of 6.

TEA [102]

Answer:

y = 6x + 18

Step-by-step explanation:

so first write y = 6x + b (because you have the slope) now to find the y-intercept input the point (-2, 6) and do algebra

6 = 6(-2) + b

6 = -12 + b

b = 18

I NEED HELP PLS THIS IS DUE IN 3 HOURS

Mariulka [41]

Answer:

Part 1) $x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})$

Part 2) $x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

Part 1)

in this problem we have

$x^{2} -2x-2=0$

$a=1\\b=-2\\c=-2$

substitute in the formula

$x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}\\\\x=\frac{2(+/-)\sqrt{12}} {2}\\\\x=\frac{2(+/-)2\sqrt{3}} {2}\\\\x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}\\\\x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}$
