Don't trust me but it's probably the first one. Just using context clues
Let x be the number of quarts of water it sells at lunch
Dinner = 2x - 36
Lunch = 2x
2x + 2x - 36 = 4x - 36
4x - 36 = 144
144 - 36 = 4x
4x = 108
x = 108 divided by 4 = 27
2x = 27 x 2 = 54
The restaurant sells 54 quarts of water at lunch.
Answer:
y = 2/5x + 4/5
or
y = 2/5x +0.8, both mean the same thing
Step-by-step explanation:
Perpendicular line would mean that the line has to go through line m at a 90 degree angle.
The first thing I would do is look at the slope already given to us for line m and flip it around and make the negative fraction a positive one so it goes up.
-5/2x -> 2/5x
The next would be to find where the line would intercept on the y-axis. It already told us it will go through the point (3,2). So with the slope we already have, count 5 to the left and 2 down. At this point I plotted this entire thing in a graphing calculator. Anyways the answer:
y = 2/5x + 4/5
