After the music store he had $14 left, because 21:3=7 and 7x2 equals 14.
After the drink, he has $3.5 left, because 14:4=3.5 and 3.5x1=3.5.
Conclusion: that is one expensive drink. (Answer is 3 dollars and 50 cents. Hope this helped:)
Answer:
b perpendicular
Step-by-step explanation:
all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites
Line 1) -7 -8 / -3 -2 X= 3X
Line 2) -3 - 0 / 12 - 3 X = -1 / 3X
Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.
Im saying C is the awnser
