Is this right or wrong?
11. Solve the inequality. Show your work.
r + 3 ≥ 7
 r + 3≥ 7
3 3
 r  ≥ 4
If I plug the the 4 into r's place
4+3 ≥7

Best ResponseYou've already chosen the best response.2for absolute value problem, you need do: \( r+3\geq 7\) \(7\geq r+3\geq 7\) \(\bullet \) first and middle : \(7 \geq r+3 \) 3 both sides \(11\geq r\), that means \(r\leq 11\) (namely *) \(\bullet\) middle and last: \(r+3\geq 7\) 3 both sides, \(r\geq 4\) (namely **) Combine * and **, you have either \(r\leq 11\) or \(r\geq 4\) is the solution for the expression.

Best ResponseYou've already chosen the best response.2Hence, your answer should be both with OR between them. I meant \(r\leq 11\) OR \(r\geq 4\)

Best ResponseYou've already chosen the best response.2stay!! just put an extra value by opposite of 7 to the left.

Best ResponseYou've already chosen the best response.2In general, if a < 7, to solve it, you put one more value on the left by opposite value of number , like 7<a<7

Best ResponseYou've already chosen the best response.0Okay. Do i include it when i'm subtarcting 3?

Best ResponseYou've already chosen the best response.2if a> 7, again, put one more value on the left 7 >a >7 On that way, you take off the absolute sign and solve part by part like above.

Best ResponseYou've already chosen the best response.2After taking off the absolute value sign, you solve as usual, no absolute value any more.
