Answer:
Step-by-step explanation:
Starting with 3 x < -18, we divide both sides by 3, obtaining x < -6.
Draw a circle centered at x = -6 and then from that circle draw an arrow to the left.
Answer:(7,-3)
Step-by-step explanation:
11°F is what the temperature was at 5:00 a.m.
V = 4/3πr³
V = 4/3(3.14)(14)³
V = 4/3(3.14)(2744)
V = 4/3(8616.16)
V = 11488.21333cm³
