Sarawong's school is selling tickets to the annual talent show. On the first day of ticket sales the
SIZIF [17.4K]

Answer:

Price of the adult ticket is $13

Price of the child ticket is $3

Step-by-step explanation:

Lets x be the adult ticket and y be the child ticket.

Given:

School sold 14 adult tickets and 14 child tickets for a total of $224, so the first equation is.

14x+14y=224-------------(1)

And the school took in $44 on the  second day by selling 2 adult tickets and 6 child tickets, so the second equation is.

2x+6y=44---------------(2)

We find the price of an adult ticket and the  price of a child ticket by solving above system of equation.

Now, equation 2 multiplied by 7.

7(2x+6y=44)

14x+42y=308---------(3)

Now, equation 1 subtracted by equation 3.

14x+42y=308

14x+14y=224

-______________

14x is cancelled in both equations, so we get the equation.

28y=84

y=\frac{84}{28}

y = 3

Now, we substitute y = 3 in equation 2.

2x+6(3)=44

2x+18=44

2x=44-18

2x=26

x=\frac{26}{2}

x = 13

Therefore, the price of the adult ticket is $13 and the price of the child ticket is $3.

What is the inverse of x-2
SCORPION-xisa [38]

Answer:

y = x + 2

Step-by-step explanation:

The expression x-2 is from the equation y = x - 2.

To find the inverse of the equation, <u>switch the "x" and "y" variables</u>, then solve  or <u>isolate for "y"</u>, meaning to separate it from the other numbers.

y = x - 2     Original equation

x = y - 2     Switched "x" and "y" variables

x + 2 = y - 2 + 2     Add 2 to both sides to cancel out '-2' on the side with "y"

x + 2 = y    

y = x + 2     Variable is on left side in standard formatting

To isolate, do the reverse operation for the number you want to get rid of.

On the side with "y", I wanted to get rid of '-2' so I could separate "y" from everything else. '+2' is the reverse operation for '-2'.

Compare the table and equation.
iren2701 [21]
The slope formula is y2 - y1/x2 - x1. 

First plug in x = 1, x = 2, and x = 3 in to the equation y = 4x to find the first 3 points(Like the first three are shown for the table.) which are (1, 4), (2, 8), and (3, 12). 
The slope of the table would be 9 - 3/3 - 1, after subtracting you get 6/2. You would then divide 6 by 2, which gives you 3. 3 is the slope of the table.

The slope of the equation goes through the same process. 12 - 4/3 - 1, after subtracting it's 8/2, and after dividing you get 4. The slope of the equation is 4. 

This means the equation has the greater slope.
