This is good information, but the question part is missing. Put the question in the comments and I'll try my best to help!
Answer:
B. The two lines are neither parallel nor perpendicular.
Step-by-step explanation:
First, put both lines into the same format. In this example, we're going to use y=mx+b format.
x - 4y = -9
-4y = -x + -9
y = (-x + -9) / -4
y = (x+9)/-4
y = (-1/4)x + (-9/4)
y = 3x - 7
If two lines are parallel, they have the same slope. (ie 4 and 4)
If two lines are perpendicular, one line's slope is the negative reciprocal of the other. (ie 4 and -1/4)
Neither is true here.
If you add each cost together the price is 47.45
Hope this helps :)
So 45% of 35 is 16.2 so subtract 16.2 from 36 and you get A 19.2
