From the second equation ,we can know that y=3.25x+0.75
plug it into the first equation
-4.5x-2(3.25x+0.75)=-12.5
-4.5x-6.5x-1.5=-12.5
-11x=-11
x=1
plug it back into the second equation, y=3.25x+0.75=4
the answer would be (1,4)
Answer:
(1,4) and (1,0)
Step-by-step explanation:
These have the same first coordinate and different second coordinates, meaning that it cannot be a function. For it to be a function, the x coordinates have to be different numbers.
the price of Adults Ticket = $15
and the price of Child's Ticket = $10
Step-by-step explanation:
Let adults be x and children be y
then Three adults and four children must pay $85 can be written as:

and Two adults and three children must pay $60 can be written as:

Solving equations 1 and 2 to find the value of x and y.
Multiplying eq(1) by 2 and eq(2) by 3

Putting value of y=10 in eq(1)

So, the price of Adults Ticket = $15
and the price of Child's Ticket = $10

The best way to plot them is by month.
170 - 110 = $60.
We are supposed to plot in months and the above calculation is in year, convert it into months
60/5 = $5 each month
So, the coordinates would be 0, 110 1, 115 2, 120 3, 125
The month will be in the x axis and your money will be the Y axis
