To determine if the given pair of lines are parallel, we are to calculate first for their slopes through the equation,
m = (y₂ - y₁) / (x₂ - x₁)
Rm (3, -4) and (1,1)
m = (1 --4) / (1 - 3) = -5/2
Rn (1,1) and (-5,16)
m = (16 - 1) / (-5 -1) = -5/2
Since the lines have the same slope, then they are parallel. The answer is true.
Answer:
The answer is dependent on how many chairs are available. Then you will be able divide the number of students by how many sections there are.
So the ornament is $16.00-3/4% off=15.88
-3/4%=0.12 So, $16.00-0.12=15.88
The ornament costs $15.88.
