Answer:
Because there are fewer than 30 (not no more than 30) one of the answer i x+y < 30
Because he needs both small and large another answer is x>0 and not x  0
Finally because he need at least dozen large cones the last answer is y

Answer:
y+3 = 2(x-4)
Step-by-step explanation:
If we have a slope and a point, we can use the point slope form for an equation of a line
y -y1= m(x-x1)
where m is the slope and (x1,y1) is the point
y--3 = 2(x-4)
y+3 = 2(x-4)
