    you don't have any negatives that you will multiply or divide both sides by so the greater than or equal to sign will not move.

    8x - 5 ≥ 27 + 5 +5 (Add 5 to both side) 5+5 cancels out, you now have 8x/8 and 32/5. So, C. c. x ≤ 4

    \[8x-5\ge27 \] +5 +5 \[8x \ge32\] divide both sides by 8 \[x \ge32/8\] x\[\ge4\]

    if it was a negative 8"" instead of positive then you would..... \[-8x \ge32\] divide by -8 \[x \le32\div-8\] \[x \le-4\]

    do the same thing and divide both sides by (-3) "this flips the sign the other way" \[x <-8\] now i'm pretty sure it doesn't want you to graph it on a plot but i'll show you both that and number line

    basically that shows the line and that everything to the left of it is where x is

    that is on the number line and the closed circle means it does not exactly touch 8, but "x"=every number before -8. even. -7.9999999999 etc
