Which graph represents the solution to the given system? y=5x+4; y=5x-3
Mars2501 [29]

Hello from MrBillDoesMath!

Answer:

The lines do not intersect


Discussion:

Where do the lines intersect?

5x + 4 = 5x - 3     =>                   subtract 5x from both sides

4         =       -3      =>  NO WAY! The lines do not intersect


Thank you,

MrB

Y= 9x -9 y= 9 substitution method
Aneli [31]
You would plug in the y=9 into the first equation and then have the expression 9=9x-9
. After going through the first steps of solving an expression you would get 18=9x. X=2. Then you would plug in the x value into the first expression to get y=9.

Word problem: $32.95 for an adult ticket and $22.95 for a junior ticket. one day, the park collected $10,612 from a total of 360
seropon [69]

x + y = 360 \\ 32.95x + 22.95y = 10612
First, solve
x = 360 - y

Substitute that into equation
32.95(360 - y) + 22.95y = 10612 \\ 11862 - 32.95y + 22.95y = 10612 \\ 11862 - 10y = 10612 \\ 10y = 1250 \\ y = 125

Substitute y = 125 into
x = 360 - 125 \\ x = 235

There were 235 adult tickets and 125 junior tickets.

Hope this helps. - M
