Which of the following number lines depicts the solution to 4(x+1) > 16 + 7x?
1 answer:
9514 1404 393
Answer:
b) x < -4
Step-by-step explanation:
Eliminate parentheses and you have ...
4x +4 > 16 +7x
-12 > 3x . . . . . . . . subtract 4x+16
-4 > x . . . . . . . . divide by 3
The number line will have an <em>open circle</em> at -4 and be shaded to the <em>left</em>. The pictures are a bit fuzzy, but we think choice B has that description.
