For the 1st one we need to solve x. x-y=2 step1: x-y+y=2+y answer: x=y+2
Plot a graph of y-axis against x-axis.
The graph should be a straight line passing through:
(-2,0.8) , (-1,-0.4) , (0,0) , (1,0.4) and (2,0.8)
Answer:

Step-by-step explanation:
From the diagram which I have drawn and attached below:

Next, in the triangle, the sum of the three interior angles:

The value of angle x is 35 degrees.
Answer:
A) The circumcenter of a right triangle falls on the side opposite the right angle
B) The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides
D.) The circumcenter is equidistant from (Apex)
Step-by-step explanation:
X + 9 = 2x - 3
<u>-x -x </u>
9 = x - 3
<u> +3 +3</u>
12 = x
