Answer:
No
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, for example:
2/3 and -3/2
It is not possible for 2 lines to have negative slopes and be perpendicuar. This is because a slope must be negated to get the perpendicular slope.
First, find the number of people who need chairs.
18 + 9 + 15 + 12 = 54
Subtract the people who cant come
54 - 6 = 48
Divide by amount of chairs per row
48/6 = 8
C. 8 rows of chairs are needed.
-4/3+1/3y I hope thats right
