Hello!
You can substitute y into the other equation
7 = -3x - 2
Add 2 to both sides
9 = -3x
Divide both sides by -3
-3 = x
The answer is -3
Hope this helps!
Answer:
(x-1)^2 + y^2 = 25
Step-by-step explanation:
center C ( ( xA + xB)/2 , (yA+yB)/2 ) = ( 1 , 0)
AB = 10
radius = AB / 2 = 5
equation formula: (x - xC)^2 + (y-yC)^2 = radius^2
Hence:
(x-1)^2 + y^2 = 25

Answer:
(7-2) x 2 -1 = 9
Step-by-step explanation:
(7-2) = 5 x 2 =10 -1 = 9
This isn't a great question, with the answer depending on how your book presents the material.
Supplementary angles are usually defined as a pair of angles which add to 180 degrees. It's then a theorem that a linear pair makes supplements.
So now we have to decide between postulate and definition for the plane formed by two intersecting lines.
Again I'd say at least from Euclid's definition this is a theorem.
none of the above
