Answer:
k = -2
Step-by-step explanation:
If 
Then

So

From this follows k = -2
<span>-2x – 4 < 10
add 4 to both sides
-2x - 4 + 4 < 10 + 4
simplify
-2x < 14
divide both sides by -2
-2x/-2 < 14/-2
simplify
x < -7</span>
Answer:
2>x
y>-1
Step-by-step explanation:
assume y=0 when finding x and vice versa
