Question

Kelsey is solving the inequality 17+4<9 17 + 4 x < 9 . To solve the inequality, she begins by solving the equation as shown. Which number line represents the solution to the inequality? 17 + 4 x = 9. Subtract 17 from both sides. 4 x = negative 8. Divide both sides by 4. X = negative 2. CLEAR CHECK A number line going from negative 10 to positive 10. A closed circle is at negative 2. A number line going from negative 10 to positive 10. Closed circles are at negative 4, negative 3, negative 2, negative 1, 0. A number line going from negative 10 to positive 10. An open circle is at negative 2. The line is shaded to the right of the circle. A number line going from negative 10 to positive 10. An open circle is at negative 2. The line is shaded to the left of the circle.

    Answer:

    an open circle will be at -2(since the inequality sign does not include “equal to”) and the line is drawn to the left of the circle (since the sign is “left than”)

    Step-by-step explanation:

    Given the inequalities

    17+4x < 9

    Subtract 17 from both sides

    17+4x -19 < 9 – 17

    4x < -8

    Divide both sides by 4

    4x/4 < -8/4

    x < -2

    To represent the solution on a number line, an open circle will be at -2(since the inequality sign does not include “equal to”) and the line is drawn to the left of the circle.
