Answer:
3 one
Step-by-step explanation:
Pretty sure the answer would be 32. It’s basic subtraction I think.
Answer:
perpendicular
Step-by-step explanation:
start but putting each line into the standard line format
2x-y=-5
-y=-2x-5
y=2x+5
x+2y=-6
2y=-x-6
y=-(1/2)x-3
if lines are parallel the slopes would be the same. 2 is not equal to -1/2
if lines are perpendicular the slope of one would be the opposite inverse of the other.
negative inverse of 2 = - (1/2)
so the lines are perpendicular
That is not a question so I can't help you but combined she did 7/4 or 1 3/4 hours
