Find the error in the calculations below, if there is one:
Line 1: -5<2x+7<9
Line 2: -12<2x<2
Line 3: -6<x <1
Line 4:
An image shows a number line. There is a filled-in circle at negative 6 and an open circle at positive 1. The number line is shaded between negative 6 and 1.
A)There are no errors.
B)The error ocurred from Line (3) to Line (4).
C)The error ocurred from Line (2) to Line (3).
D)The error ocurred from Line (1) to Line (2).
B) The error occurred from Line (3) to Line (4).
The inequality x < 1 should be changed to x ≤ 1 in order to accurately represent that the circle at positive 1 is filled in.
