The lines are
i) y=-x+6
ii) y=2x-3
The solution of the system of equations is found by equalizing the 2 equations:
-x+6=2x-3
-2x-x=-6-3
-3x=-9
x=-9/(-3)=3
substitute x=3 in either i) or ii):
i) y=-3+6=3
ii) y=2(3)-3=6-3=3
(the result is the same, so checking one is enough)
This means that the point (3, 3) is a point which is in both lines, so a solution to the system.
In graphs, this means that the lines intersect at (3, 3) ONLY
Answer: The graph where the lines intersect at (3, 3)
Answer:
public class MovieRental
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Enter the number of movie rentals: ");
int movieRentals = in.nextInt();
System.out.print("Enter the number of members referred to the video club: ");
int memberReferral = in.nextInt();
in.close();
double discountVal = Math.min(movieRentals + memberReferral, 75);
System.out.println("The discount is equal to: " + discountVal);
}
}
Answer:
y = 2x-5
y=-x+4
Step-by-step explanation:
Just need to solve the:
x+y=4
y-2x=-5
And we have:
x=3
y=1
Then replace x and y into the answer to find the correct one
