Step-by-step explanation:
Answer:
k<1
Step-by-step explanation:
1. Add 32 to both sides
-16k-32+32>-48+32
2. Simplify
-16k>-16
3. Reverse the sign (You only reverse the sign if you are DIVIDING BY a negative.)
-16k/-16 = k
-16/-16 = 1
You're left with k < 1
Your number line graph should be an open circle at 1 going to the left.
