In polynomials, when a term contains both a number and a variable part, the number is called the co-efficient.
In this problem the co-efficient of x =
(8+y)+(3x+y2)
3y+3x+8
Therefore the co efficient of x and y is 3
The answer is 110 adult tickets. Let x= student tickets and y= adult tickets.
We know that the total tickets sold was 440. That means the total number of student tickets (x) plus the total number of adult tickets (y) equaled 440. Putting it into an equation, you get:
x+y=440
Now we know that the amount of student tickets is equal to three times as many adult tickets, so in an equation that is seen as:
x=3y
In order to solve for one variable, plug in 3y for the x value of the first equation to get:
y+3y=440
then solve:
4y=440
y= 440/4
y=110
The total number of adult tickets sold was 110 tickets.

(f - g)(x) = - x² + 4x + 6
Step-by-step explanation:
If f(x) and g(x) are two functions, then
- (f + g)(x) = f(x) + g(x)
- (f - g)(x) = f(x) - g(x)
- (f . g)(x) = f(x) . g(x)
- (f/g)(x) = f(x)/g(x), where g(x) ≠ 0
Now lets solve the question
∵ f(x) = 4x + 1
∵ g(x) = x² - 5
- To find (f - g)(x) subtract g(x) from f(x)
∵ (f - g)(x) = f(x) - g(x)
∴ (f - g)(x) = (4x + 1) - (x² - 5)
- Multiply the bracket (x² - 5) by (-) and remember (-)(-) = (+)
∴ (f - g)(x) = 4x + 1 - x² + 5
- Add the like terms in the right hand side
∴ (f - g)(x) = 4x + (1 + 5) - x²
∴ (f - g)(x) = 4x + 6 - x²
- Arrange the terms from the greatest power of x
∴ (f - g)(x) = - x² + 4x + 6
(f - g)(x) = - x² + 4x + 6
