Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 = 
( multiply both sides by 3 )
24 = k
y = 
← equation of variation
Answer:
The zeros are x=7 and x= -6
Step-by-step explanation:
In order to find the zeros of a function with factors, we have to equate the factors to zero.
So x-7 = 0
and
x+6 = 0
Then we solve for x in each equation,
x= 7 and x= -6
These values are the zeros

Step-by-step explanation:
Start by finding original number of pens:
15 boxes x 40 pens per box = 600 pens in all
