    Q3.  What inequality does the number line graph represent? - ProProfs

    Q3.  What inequality does the number line graph represent?

    • A   x ≤ 4

    • B   x ≥ -4

    • C  x < -4

    • D  x < 4

    Correct Answer
    A. C  x < -4
    Explanation
    The number line graph represents the inequality x < -4. This is because all the numbers to the left of -4 on the number line satisfy the inequality, while all the numbers to the right of -4 do not satisfy the inequality.

    Q5.  Translate the following phrase: You and your friends ate more than 8 slices of pizza at the party.

    • A  x > 8

    • B  x ≤ 8

    • C  x < 8

    • D  x ≥ 8

    Correct Answer
    A. A  x > 8
    Explanation
    The phrase "You and your friends ate more than 8 slices of pizza at the party" implies that the number of slices of pizza eaten is greater than 8. Therefore, the correct answer is A. x > 8.

    Q2.   Solve and graph the inequality.           77 ≤ 5 + 8n - ProProfs

    Q2.   Solve and graph the inequality.           77 ≤ 5 + 8n

    • A

    • B

    • C

    • D

    Correct Answer
    A. D
    Explanation
    The correct answer is D because when solving the inequality, we subtract 5 from both sides to isolate the variable: 77 - 5 ≤ 5 + 8n - 5. Simplifying, we get 72 ≤ 8n. Then, we divide both sides by 8 to solve for n: 9 ≤ n. This means that n is greater than or equal to 9. When graphing this inequality on a number line, we shade the region to the right of 9 to represent all the possible values of n that satisfy the inequality.
