The solutions are

Answer:
yes, y=2x-3 is linear
2x - y = 3 Standard Form
Step-by-step explanation:
since both the 'x' and 'y' variables have one as their exponents then this represents a linear equation
standard form: Ax + By = C
y = 2x - 3
subtract 2x from each side to get:
-2x + y = -3
divide each term by -1 to get (this is done so the leading coefficient is not negative)
2x - y = 3 Standard Form
Answer:
120 degrees
Step-by-step explanation:
This is a quadrilateral, and by definition, the sum of all the interior angles is 360. So, we can just sum up all the expressions and set them equal to 360:
2x + x + 2x + x = 360
Combine like terms and solve for x:
6x = 360
x = 360/6 = 60
<BCD = 2x = 2 * 60 = 120
Thus, the answer is 120 degrees.
Hope this helps!
