Answer 6

In algebra, disjunction refers to the combining of math sentences with the word "OR." Some refer to this as a union of two or more sentences.

Answer 7

I guess it is more of the same. So for the first one, what would you do first?

Answer 8

divide -6 by -3

Answer 9

Yes, and also flip the symbol, since dividing by negative

Answer 10

which is ?

Answer 11

x>2

Answer 12

yes. ok, next one.

Answer 13

to isolate the x, you should do what?

Answer 14

x\[\le\]-7?

Answer 15

Yes, \[x \le -7\] by subtracting the five each side

Answer 16

then graph

Answer 17

So, \[x \le -7\] and x>2
Let's flip the one with the -7 in it to give \[-7 \ge x\]

Answer 18

hang on. let me check that

Answer 19

ok

Answer 20

Ok, this one doesn't combine.
x≤−7 and x>2

Answer 21

how would i graph this?

Answer 22

So, filled in circle at -7, and open circle at 2.
Then since x is smaller than -7, draw arrow to the left, for the values less than -7. also draw arrow to the right from the 2, showing values above 2
