Q. Is (2,8) a solution to the inequality 3x+8y<9? Choices:(A)yes(B)no
Substitute values into inequality: Substitute the values (2,8) into the inequality 3x+8y<9. The substituted inequality is 3(2)+8(8)<9.
Calculate left side: Calculate the left side of the inequality 3(2)+8(8). Simplify it to get 3×2+8×8 which equals 6+64.
Add numbers: Add the numbers 6+64 to get 70. So, the inequality becomes 70<9.
Determine inequality truth: Determine if the inequality 70<9 is true. Since 70 is not less than 9, the inequality is false. Therefore, the point (2,8) does not make the inequality 3x+8y<9 true.
