What is the y-coordinate of the solution for the system of equations? x−y=−11 y+7=−2x
ICE Princess25 [194]

Answer:

y= 5

Step-by-step explanation:

Given the system of equations:

x-y=-11

y+7=-2x

In order to find the y coordinate of the solution we must first find the solution to this system of equations. We first start by solving one of the given equations and then substitute the answer of that into the second equation and further solve to get the final answers.

x=y=-11

y+7=-2x

y+7=-2x

+ -7

y = -2x - 7

x - y = -11

y = -2x-7

x-(-2x-7)=-11

x--2x=x+2x=3x

3x+7=-11

-7

-11+-7=-18

3x=-18

\div3

-18\div3=-6

x=-6

y=-2x-7

y=(-2)(-6)-7

-2\times-6=12-7=5

y=5

Hope this helps.

AnnyKZ [126]

Answer:

<u>The correct answer is D. obtuse scalene</u>

Step-by-step explanation:

1. Let's recall that a equilateral triangle has its three sides of the same length. An equilateral triangle is always equiangular. This is not our given triangle.

2. Let's recall that an isosceles triangle has two sides of the same length. This is not our given triangle.

<u>3. Finally, let's recall that in a scalene triangle, none of the sides are the same length. And if one of the given angles is greater than a right angle, measures more than 90 degrees, it is an obtuse triangle. This is our given triangle.</u>

<u>The correct answer is D. obtuse scalene.</u>
