Question

-1 < 2x + 5 < 13 is an example of a disjunction.

True
False

Answer 1

i think its true

Answer 2

it's true :)

Answer 3

yayy!!

Answer 4

Solve the combined inequality and select the answer that best describes the graph of the solution.

4x + 6 > 2 and 8x – 6 < 26

Open dot at -1, closed dot at 4, and shaded between the numbers

Closed dot at -1 and 5, shaded between the numbers

Closed dot at 1, open dot at 5, and shaded between the numbers

None of the above

Answer 5

4x+6>2 Subtract both sides by 6
4x>-4 Divide both sides by 4
x>-1

8x-6<26 Add both sides by 6
8x<32 Divide both sides by 8 and we get
x<4

I'm pretty sure it's none of the above. The only way the line would have a closed dot is if the inequality sign was greater than or equal to/lesser than or equal to. In this case it would all have to be open dots so it's none of the above.
