1. -2x<or=-8 (subtract 6 from each side);
1. -5 * -1/5x>2*-5 (multiply both sides by -5);
Interval notation starts with the lowest value & goes toward the highest value, with x in the middle:
Notice that we had to turn x>-10 backward, in order to show that there are values of x in between -10 & 4 that are the solution set. As my iPhone doesn't seem to offer me a "greater than or equal to" sign, I have made a variation here that I believe is comprehensible. You will use the standard sign.
