Answer:
1.
If two angles are supplementary, their sum is 180 degrees.
Check: 10 + 170 = 180
=> Maryam's claim is correct
If two angles are complementary, their sum is 90 degrees.
Check: 81 + 9 = 90
=> Ailia's claim is correct
2.
As the definition:
Vertical angles have sides that form two pairs of opposite rays.
Adjacent angles have a common side and don't overlap.
=> As provided pair of angles, they are adjacent pair of angles.
=> Ahmed's statement is wrong, Saalem's statement is correct.
Hope this helps!

Step-by-step explanation:
a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5.
Answer:
that is the solution to the question
If you are looking for the equation, then it would be y = -x+3
This is the same as y = -1x+3 which is in slope intercept form y = mx+b
m = -1 = slope
b = 3 = y intercept
If you want to graph this, then plot the points (0,3) and (1,2). Then draw a straight line through them both. Extend the line in both directions as much as possible.
