A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.
Answer: the range for one game is {$0, $2,590,000}
Step-by-step explanation:
The revenue, on average, can be written as:
Y = $35*x
where y is the revenue and x is the number of tickets sold.
The domain of this function is equal to {0, 74000} this means that they can sell any whole number of tickets between 0 and 74000.
To find the range we need to evaluate y in bot extremes of the domain (because we have a linear relation)
minimum revenue
y(0) = $35*0 = $0
maximum revenue
y(74000) = $35*74000 = $2,590,000
So the range for one game is {$0, $2,590,000}
Answer:
-16
Step-by-step explanation:
The given linear function is ; 
Let 
.
We interchange x and y.
.
We solve for y.
.
We now multiply through by 
to get:
.
This simplifies to;
.
Hence 
.
The y-intercept is -16
To write a fraction in simplest form, you have to divide the numerator and the denominator by their greatest common factor.
Factors of 10: 1, 2, 5, 10
Factors of 64: 1, 2, 4, 8, 16, 32, 64
Common Factors: 1, 2
Greatest Common Factor: 2
Answer:
(2,22)
Step by step explanation:
(x,22) is the solution of the equation y=9x+4
9x+4= 22
=>9x= 22-4
=>9x=18
=>x= 2
