|x+3| +7 less than or equal to 10 Describe the graph of the solution in a complete sentence.
you can write it this way |x+3| + 7 <= 10 (use <= if you can't type ≤ ) the first step is add -7 to both sides |x+3| + 7 -7 <= 10-7 and simplify. 7-7 is 0 on the left side. 10-7 is 3. you get |x+3|≤ 3 now that you have just an absolute value sign on the left side, we can write it as two different equations: 1) x+3 is positive, so the | | do nothing: x+3 ≤ 3 add -3 to both sides, simplify, and get x ≤3 2) x+3 is negative. the | | will make it positive. This is the same as saying multiply by -1: -1(x+3) ≤ 3 distribute the -1 (multiply each term inside the parens by -1) -x - 3 ≤ 3 add +x to both sides -3 ≤ x - 3 add + 3 to both sides 0 ≤ x you have the two solutions: 0 ≤ x x ≤3 when says: x greater than or equal to zero, and less than or equal to 3 (all the numbers from 0 up to 3) you can also write the answer as 0 ≤ x ≤ 3
