9. Lorenzo sells adult and student tickets to an upcoming basketball game. He sells more student tickets than adult tickets. The adult tickets are $5 each and the
student tickets are $3 each. He sells more than $900 worth of tickets in total.
The system of linear inequalities that describes this situation, where x is the
number of adult tickets and y is the number of student tickets, is shown below.
{5x+3y=900
Which of the following statements is true regarding the ordered pair (150,400.5)?

irrational, cannot

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
