Answer:
(3/2)
Step-by-step explanation:
A perpendicular line has a slope that has the negative inverse of the reference line. The green line's slope of <u>-(2/3) becomes (3/2) for a perpendicular line</u>. The red line has two points we can use to calculate slope, just to check.
(-3,-5) and (5,7)
Rise = (7 - (-5)) = 12
Run = (5-(-3)) = 8
Slope = (12/8) or (3/2)
Answer:
There are 27 boxes are on the shelf at the start of the day.
Step-by-step explanation:
Let number of boxes are on the shelf at the start of the day is x
According to given situations :
On one day, a store sold 16 boxes of rice
i.e, 
Restocked the shelf with 22 boxes,
⇒ 
But 27 boxes sold
⇒
Restocked with 30 boxes,
⇒
But 15 boxes sold,
⇒

There are now 21 boxes of rice on the shelf.
So, 

Therefore,There are 27 boxes are on the shelf at the start of the day.
