Inequality conjunctions
1 answer:
Answer:
See pictures attached
Step-by-step explanation:
The conjunction is given by the intersection of 2 inequalities
-5 < x (or x > -5)
that is the set of real number such that x greater than -5, graphically is represented by picture 1 attached (the parentheses means that -5 IS NOT included)
and the inequality
x ≤ 7
which is the set of real number such that x less than or equal to 7, represented in picture 2 attached (the bracket means that 7 IS included)
When we intersect the two sets we obtain
– 5 < x ≤ 7
that is the set of numbers x such that x is greater than -5 AND x less than or equals to 7, which graphically is represented in picture 3 attached.
