Question

Solve the compound inequality 9 + 3n greater than or equal to 3 or 5n < 30.
can someone help me with this plz

Answer 1

\[9+3n \ge3\]
\[5n <30\]
Are these the two inequalities?

Answer 2

yes

Answer 3

yes

Answer 4

Note:This system of inequalities can also be solved by graphical method.

9+3n >= 3 .....(1)
n >= -2
So, n= [-2, infinity)
and
5n < 30 ........(2)
n < 6
So, n=(-infinity,6)

Combining both the partial solutions
n=[-2,6)
