Answer:
2x-y=-1
Step-by-step explanation:
y + 9 = 2(x + 5)
y + 9 = 2x + 10 [distribute]
y = 2x + 1 [subtract 9 from both sides]
y - 2x = 1 [subtract 2x from both sides]
-2x + y = 1 [put x first]
2x - y = -1 [multiply by -1 to make x coefficient positive]
to find the value of this expression, it would be easiest to use the distributive property.
(V9)2 +10
= 18V+90V
= 108V

Your answer is D.
Because there are no negative reciprocals, therefore there are no right angles.
Answer:
8.5
Step-by-step explanation:
Since this is a 45-45-90 triangle, n = 9 and m = x
