Q. Does (1,3) make the inequality 2x+6y≥20 true?Choices:(A)yes(B)no
Substitute values into inequality: Substitute the values (1,3) into the inequality 2x+6y≥20. The substituted inequality is 2(1)+6(3)≥20.
Calculate left side: Calculate the left side of the inequality 2(1)+6(3). Simplify it to get 2+18.
Find sum: Add the numbers together to find the sum. 2+18 equals 20.
Check inequality: The inequality 2(1)+6(3)≥20 becomes 20≥20. Now, determine if the point (1,3) makes the inequality 2x+6y≥20 true. Since 20 is equal to 20, the inequality holds true.
