Answer:
• The function is a linear function
• The function changes at a constant rate
Step-by-step explanation:
A graph of the function shows it to be a straight line (linear function). Such a function always changes at a constant rate. The line goes downward to the right, so the function is a decreasing function.
___
"changes at a constant rate" and "linear function" are two different ways of saying the same thing: the graph of the function is a straight line.
To find the answer we can find the amount he will get paid separately.
The amount he will get paid on site A:
0.75 x 5
=$3.75
The amount he will get paid on site B:
0.25 x 5
= $1.25
To find the amount Joe get paid at site A than at site B, we can deduct the amount he get from site B by the amount he get from site A:
= 3.75 - 1.25
= $2.50
Therefore $2.50 is the answer.
Hope it helps!
Answer: 200 adult tickets and 400 student tickets were sold.
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of student tickets that were sold.
Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $850, the expression would be
1.75x + 1.25y = 850- - - - - - - - - -1
Suppose there are twice as many student tickets sold as adult tickets. This is expressed as
y = 2x
Substituting y = 2x into equation 1, it becomes
1.75x + 1.25 × 2x = 850
1.75x + 2.5x = 850
4.25x = 850
x = 850/4.25
x = 200
y = 2x = 2 × 200
y = 400
