Question 1 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY

Which are correct representations of the inequality 6 x is greater than or equal to 3 plus 4 times open paren 2 x minus 1 close paren ? Choose three correct answers.

Answer
A
1 is greater than or equal to 2 x
B
Image with description A number line from negative 1 point 5 to positive 1 point 5 in increments of 0 point 5. A solid point is at positive 0 point 5 and a bold line starts at positive 0 point 5 and is pointing to the left.
C
Image with description A number line from negative 1 point 5 to positive 1 point 5 in increments of 0 point 5. A solid point is at negative 0 point 5 and a bold line starts at negative 0 point 5 and is pointing to the right.
D
6 x is greater than or equal to 3 plus 8 x minus 4
E
Image with description A number line from negative 1 point 5 to positive 1 point 5 in increments of 0 point 5. A solid point is at positive 0 point 5 and a bold line starts at positive 0 point 5 and is pointing to the right.

Explanation

Distribute 4 in the original inequality: 3 + 4(2x − 1) = 3 + 8x − 4, so choice A is equivalent. Simplifying 6x ≥ 8x − 1 gives 1 ≥ 2x, or x ≤ 0.5, which is choice E. On a number line, x ≤ 0.5 is shown by a solid point at 0.5 with shading to the left, as in choice C.
