Q. Is (1,4) a solution to this system of inequalities?8x+y≥63x+2y<18Choices:(A)yes(B)no
Check Point 1,4: Does the point 1,4 satisfy the inequality 8x+y≥6?Substitute 1 for x and 4 for y in 8x+y≥6.8(1)+4≥68+4≥61,40Since 1,40 is true, 1,4 satisfies the inequality 8x+y≥6.
Check Inequality 1: Does the point (1,4) satisfy the inequality 3x + 2y < 18?Substitute 1 for x and 4 for y in 3x + 2y < 18.3(1) + 2(4) < 183 + 8 < 1811 < 18Since 11 < 18 is true, (1,4) satisfies the inequality 3x + 2y < 18.
Check Inequality 2: Is (1,4) a solution to the system of inequalities?Since (1,4) satisfies both inequalities:12≥6 (true)11 < 18 (true)Therefore, (1,4) is a solution to the system of inequalities.
