Solve (x + 2 < 5) ∩ (x - 7 > -6).
mihalych1998 [28]

Answer:

<h2>1. {x | 1 < x < 3}</h2>

Step-by-step explanation:

x + 2 < 5           <em>subtract 2 from both sides</em>

x + 2 - 2 < 5 - 2

x < 3

x - 7 > -6        <em>add 7 to both sides</em>

x > 1

From x < 3 and x > 1 we have 1 < x < 3

Solve the combined inequality x + 3 &gt; -5 and -4x ≥ -16 showing all of your work
ad-work [718]
Well for the first one you have to subtract 3 on both sides so that would make the equation x > -8 (because a negative subtracting a positive is basically a negative plus negative) and so your equations done.  For the second one you divide both ides by -4 so your equation would be x < 4 (the sign would be less then or qual to because you divided by a negative)
