Answer:

to have an infinite number of solutions, the lines have to be on top of each other.....basically, they have to be the same line.

y = 3x - 1

-3x + y = -1.....multiply by -1

3x - y = 1 <== this would be ur other equation because if u put this in slope intercept form (y = mx + b), it would be the same as y = 3x - 1

Atlantic auditorium has 850 seats. Tickets were sold for 816 of the seats. For what percent of the seats were the tickets sold?
Mariana [72]

Answer:

<u>96 percent</u> of the seats were the tickets sold.

Step-by-step explanation:

Given:

Atlantic auditorium has 850 seats. Tickets were sold for 816 of the seats.

Now, to find percent of the seats of the tickets sold.

Total number of seats = 850.

Tickets sold for the total seats = 816.

So, to find the percent of the seats of the tickets sold:

\frac{816}{850}\times 100

=0.96\times 100

=96\%.

Therefore, 96 percent of the seats were the tickets sold.

grigory [225]
  • Length be x
  • Breadth be y

\\ \rm\Rrightarrow 2x+2y=28

\\ \rm\Rrightarrow x+y=14--(1)

And

  • xy=45

\\ \rm\Rrightarrow (x-y)^2=(x+y)^2-4xy

\\ \rm\Rrightarrow (x-y)^2=14^2-4(45)=196-180

\\ \rm\Rrightarrow (x-y)^2=16

\\ \rm\Rrightarrow x-y=4--(2)

Adding (1) and (2)

  • 2x=18
  • x=9

And

  • 9+y=14=>y=5
