Question

PLEASE HELP WITH THESE!! THANK U SOOO MUCH!!

Answer 1

Answer:

Step-by-step explanation:

One

Since you are asked to solve this using a graphing tool, here is the results as graphed by Desmos.

The point you want is (3,2)

The answer is 2.

Two

Multiply the second equation by 2

2[0.5x - y = 10]

x - 2y = 20              Add the first equation

x + 2y = 16      

2x = 36                   Divide by 2

x = 36/2

x = 18

Since this is all you are asked for, x = 18 is the answer.

Three

y is an exterior angle.

It is the sum of the two (given) remote interior angles.

y = 35 + 105

y = 140

x and y are supplementary (they add up to 180o

x + y = 180

x + 140 = 180

x = 180 - 140

x = 40

y - x = 140 - 40

y - x = 100
