Q. Is (1,5) a solution to this system of inequalities?y≤x+4y≤8x+9Choices:(A)yes(B)no
Check Point (1,5): Does the point (1,5) satisfy the inequality y≤x+4?Substitute x=1 and y=5 into the inequality y≤x+4.5≤1+45≤5The point (1,5) satisfies the inequality y≤x+4.
Verify Inequality y≤x+4: Does the point (1,5) satisfy the inequality y≤8x+9?Substitute x=1 and y=5 into the inequality y≤8x+9.5≤8×1+95≤8+95≤17The point (1,5) satisfies the inequality y≤8x+9.
Verify Inequality y≤8x+9: Is (1,5) a solution to the system of inequalities?Since (1,5) satisfies both inequalities y≤x+4 and y≤8x+9, it is a solution to the system of inequalities.
