Answer:

(45,60)

Step-by-step explanation:

in a parallelogram, opposite angles are equal measure

2x-10 = y + 20

angles that lie on the same line add up to 180, since alternate angles of parallel lines and a transversal are equivalent

2x + 10 + 2x - 10 = 180

solving the equation with only Xs

4x = 180

x = 180/4 = 45

plug x = 45 into x and y equation

90-10 = y+ 20

80 = y + 20

y = 80-20 = 60

Determine if the following graph is a function
sweet [91]

9514 1404 393

Answer:

  yes, it is a function

Step-by-step explanation:

A graph represents a functional relationship if no vertical line intersects the graph in more than one point. A horizontal line passes this "vertical line test," so represents a function.
