Does (x, y) satisfy the inequality?

Full solution

Q. Does

(1,\,2)

make the inequality

3x + 5y < 13

true?

\newline

Choices:

\newline

(A)yes

\newline

(B)no

Substitute Values: Substitute the values $(1, 2)$ into the inequality 3x + 5y < 13. The substituted inequality is 3(1) + 5(2) < 13.
Simplify Left Side: Simplify the left side of the inequality $3(1) + 5(2)$ to find the sum. This simplifies to $3 + 10$ , which equals $13$ .
Check Inequality: The inequality 3(1) + 5(2) < 13 becomes 13 < 13. Now, determine if the point $(1, 2)$ makes the inequality 3x + 5y < 13 true. Since $13$ is not less than $13$ , the statement is false. Therefore, the point $(1, 2)$ does not make the inequality 3x + 5y < 13 true.
