We could solve for 'x' in the 2nd equation and then plug that into the first equation for 'x' and solve for 'y':
Subtract 6y to both sides:
Divide -2 to both sides:
Plug in 3y + 17 for 'x' in the first equation:
Distribute 5:
Combine like terms:
Subtract 85 to both sides:
Divide 17 to both sides:
This is the y-coordinate of the solution.

Answer: <em>50°</em>
Step-by-step explanation:
<em>Since angle 3 is in a right triangle we can assume one angle is 90°</em><em> </em><em>and then the other missing angle will be 40°</em>
<em>Because you take 180°-140°(the angle next to it) which will equal 40°</em>
<em>Now every triangle must add up to 180°</em>
<em>so lets take the angles we have now</em>
<em>90° +40°=130°</em>
<em>now take that 130°</em>
<em>180°-130°=</em><em>50°</em>
<em>Now check your work</em>
90°+40°+50°=180°
Angle 3 is 50°
Answer:
3x(3x + 2)
Step-by-step explanation:
4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
