Answer:

y = 9/2 or 4.5

Step-by-step explanation: hope this helps :)

x-y= -5 So what you do here is isolate the variables

+y +y

x = -5+y

After you do this you input the equation as x

2x+y = -1

2(-5+y) = -1

-10 + 2y = -1

+ 10 +10

2y = -9

/2 /2

y = 9/2 or 4.5

Answer:

SAS

Step-by-step explanation:

We must prove that triangles ABC and EDC are congruent.

Since BD bisects AE, then AC is congruent with CE.

Since AE bisects BD, then BC is congruent with CD

Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.

Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.

5. What is an equation of the line in slope-intercept form?

Answer:

y = (2/7)x -12

Step-by-step explanation:

y = mx + b is the standard form of an equation of a straight line in which m is the slope and b is the y-intercept (the value of y when x is zero)..

m=(2/7) and b = -12

y = mx + b

y = (2/7)x -12
