Answer:
12 units
Step-by-step explanation:
The given function is

where, S(q) is the price in dollars at which q units are supplied.
We need to find the quantity supplied in a month when the company sets the price of its olive oil press at $12,820.
Substitute S(q)=12820 in the given function.

Subtract both sides by 12820.

Taking out GCF.

Now solve the equation for q by splitting the middle term.



Using zero product property we get


q is number of units. So the value of q can not be negative.
Therefore the quantity supplied in a month when the company sets the price of its olive oil press at $12,820 is 12 units.
Answer:
x=3
Step-by-step explanation:
I am assuming that your equation is:

Subtract 4 from both sides to get:

Square both sides to get:



Divide both sides by 8 to get:

Answer:
the answer is 28 if you multiply if not 30

Actually Welcome to the Concept of the Factorisation.
Since here both are the roots of the quadratic equation in the factor form, hence
equate them to zero, to get the value of x
hence,
2x-9 = 0
===> x = 9/2
and
3x+5=0
===> x = -5/3
