Answer is the 3rd choice, -4x + 16 ≤ 3x - 5
Step by step
We know a closed circle on the number line means less /more than or equal to
So the correct answer has to be one of the last two
Solve #3
-4x + 16 ≤ 3x - 5
Subtract 3x from both sides to combine variables
-4x -3x + 16 ≤ 3x - 3x - 5
-7x + 16 ≤ -5
Now subtract 16 from both sides to isolate x
-7x + 16 - 16 ≤ -5 -16
-7x ≤ -21
Divide both sides by -7 to solve for x
-7/-7 x ≤ -21 /-7
X ≤ 3
This is the correct one because the line on the number line goes left with its arrow equal to 3 and less than 3
The last choice would by greater than or equal to 3 which is not correct
