Answer:
y = (-5/3)x+20
Step-by-step explanation:
Parallel lines have the same slope.
Answer:
i think its the 2nd one
Step-by-step explanation:
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B
9/5= 1.8 and 5/1= 5 so 1.8/5= 0.36 or 36/100 /2 18/50 9/25 answer : .36 or 9/25
