4x + 1 <= 5 ; x = 1
4x +1 >= -5 ; x = - 1.5
Now we know that x is between -1.5 and 1, so you should shade between -1.5 and 1. The circle will be closed since the equality is =< and =>
The answer is option D
Hope this helps
A. You can remember which axis is which by Y-axis is the vertical one (Y to the sky) and X- axis is horizontal. it's not C because you don't have a second point. It's not (0,4) it's just 4.
J= obtuse
K=right
L=acute
M=acute
7x + 17 = 7x - 17
7x + 17 - 7x = 7x - 17 - 7x
17 = -17
Inconsistent: for no value of x is the above equation true. 17 ≠ -17.
Hope this helps! :)
