insens350 [35]

[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2

-6x -3y = 27
-6x + 22 = 2y

-6x +27 = 3y
-6x +22 = 2y

5 = y

-6x -3x5 = 27
-6x -15 = 27

What is the slope of the line below

Fofino [41]

Answer:

C. $\frac{1}{2}$

Step-by-step explanation:

You can use the formula to find the slope: $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

(-1.5, 1.5) & (1.5, 0)

$\frac{0-(-1.5)}{1.5-(-1.5)} =\\\\\frac{0+1.5}{1.5+1.5} =\\\\\frac{1.5}{3} =\\\\\frac{1}{2}$

The slope is $\frac{1}{2}$

Classify the following based on sides and angles.

matrenka [14]

Answer:

D. right; scalene

Step-by-step explanation:

As you can see in the diagram you have a 90, 50, and 40 degrees angles. Because one of the angles is equal to 90 degrees (a right angle) this triangle can be classified as a right triangle.

No congruent sides are shown.... That means it's a scalene.
