Question

What does r equal?pls help me

Answer 1

Answer:
`r \ge -(49)/(11)`

r is greater than or equal to the fraction -49/11

==========================================================

Work Shown:

`r + 5(-2r-10) \le -4r - 1 + 6r\\\\r - 10r - 50 \le -4r - 1 + 6r\\\\-9r - 50 \le 2r - 1\\\\-9r-2r \le - 1 + 50\\\\-11r \le 49\\\\r \ge (49)/(-11)\\\\r \ge -(49)/(11)\\\\`

Note how the inequality sign flips. This happens any time you divide both sides by a negative number.

Answer 2

r ≥ -49/11

Simplified versions: r ≥ -4.45 or r ≥ -4 5/11
