Q. x−6y>57x+2y≥4Is (10,−2) a solution of the system?Choose 1 answer:(A) Yes(B) No
Step 1: Check inequality with (10,−2): Does the point (10,−2) satisfy the inequality x-6y > 5?Substitute x=10 and y=−2 in the inequality x-6y > 5.10 - 6*(-2) > 510 + 12 > 522 > 5The point (10,−2) satisfies the inequality x-6y > 5.
Step 2: Substitute values in inequality: Does the point (10,−2) satisfy the inequality 7x+2y≥4?Substitute x=10 and y=−2 in the inequality 7x+2y≥4.7⋅10+2⋅(−2)≥470−4≥466≥4The point (10,−2) satisfies the inequality 7x+2y≥4.
Step 3: Simplify the inequality: Is (10,−2) a solution to the system of inequalities?Since (10,−2) satisfies both inequalities x-6y > 5 and 7x+2y≥4, it is a solution to the system of inequalities.
