Question

-3<2x+3< or equal to 5

Answer 1

Answer:

B

Step-by-step explanation:

-3 < 2x + 3 <= 5

-6 < 2x <= 2

-3 < x <= 1

such a condition is an "and" condition. both parts need to be fulfilled.

-3 < x and x <= 1

if you are still not seeing it :

-3 < x is the same as x > -3

now you see that B is the right answer.

x > -3 and x <= 1

Answer 2

Answer: b

Step-by-step explanation:

2x + 3 > -3

2x + 3 ≤ 5

x > -3

x ≤ 1

{x | -3 < x ≤ 1} or x ∈❬-3,1]
