Question

Solve the compound inequality 9 + 3n greater than or equal to 6 or 5n < 25.

n less than or greater to −1 or n < 5

n greater than or equal to −5 or n > 5

n greater than or equal to −1 or n < 5

n less than or greater to −5 or n > 5

Answer 1

=)

Answer 2

if you start with
9+3n≥6

you should simplify it. Add -9 to both sides (like this)
-9+9+3n ≥ 6-9

can you finish?

Answer 3

one moment

Answer 4

(-9+9)+3n ≥ 6-9
0+3n ≥ -3
3n≥-3

now divide both sides by 3 (and remember that 3/3 is 1)

Answer 5

ik, srry i was checkin somethin on fb -----> its n<-1 but idk how to putthe line under

Answer 6

how did you make this ≥

Answer 7

just type n <= -1 for n≤ -1

now do the other condition
5n < 25

Answer 8

n<5

Answer 9

but idk which option its is above

Answer 10

9+3n≥6
becomes
3n≥-3

n ≥ -1 (read this as n greater than or equal to -1)
or
n<5


btw
its n<-1 but idk how to putthe line under

***you should not flip the sign.***
