Answer:
Step-by-step explanation:
They wanted to complete the square so they took the thing in front of x and divided by 2 then squared. Whatever you add in, you must take out.
Now we are read to write that one part (the first three terms together) as a square:
I don't see this but what happens if we find a common denominator for those 2 terms after the square. (b/2a)^2=b^2/4a^2 so we need to multiply that one fraction by 4a/4a.
They put it in ( )
I'm going to go ahead and combine those fractions now:
I'm going to factor out a -1 in the second term ( the one in the second ( ) ):
Now I'm going to add (b^2-4ac)/(4a^2) on both sides:
I'm going to square root both sides to rid of the square on the x+b/(2a) part:
Now subtract b/(2a) on both sides:
Combine the fractions (they have the same denominator):
Answer:
Company needs to sell at least 34 tickets in order to make a profit.
Step-by-step explanation:
Given:
Rent for the space = $300
Cost per tickets = $9
Let the number of tickets sold be 'x'
We need to find the least number of tickets to be sold to make profit
Now total profit can be made if amount which is made after selling number of tickets is greater than 300.
Hence the equation can be framed as,
Solving the equation to find the value of x we get;
We will use Division property and divide both side by 9 we get;
Tickets which need to be sell cannot be in point value hence rounding to whole number we get;
Hence Company needs to sell at least 34 tickets in order to make a profit.
