I think u divide or multiply
The line Y = 1 is a horizontal line; its slope is zero.
A line perpendicular to Y = 1 is a vertical line.
Its slope is undefined.
(This does NOT mean that it's infinite, or anything else.
The slope of a vertical line is undefined. It doesn't have
a name or a symbol. It's nothing.)
Answer:
Step-by-step explanation:
v+2.5c=191.5 and c+v=103, so c=103-v, using this c in first equation gives you
v+2.5(103-v)=191.5
v+257.5-2.5v=191.5
-1.5v=-66
v=44
So 44 vegetarian wraps were sold.
