Can someone please explain(ignore the lines i’ve drawn on i don’t think they are
correct)

Step-by-step explanation:

1.open the compass more than half of the distance between C and D, and scribe arcs of the same radius centered at C and D.

2. Call the two points where these two arcs meet A and B. Draw the line between A and B.

3. AB is the perpendicular bisector of the line segment CD. Call the point where AB intersects CD E.

This website offers a pretty good explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
