Can someone me with this math problem pls? how would i show my work in this question?

(3 * 10^9)= 3 * 1,000,000,000 = 3,000,000,000

(5*10^6)= 5 * 1,000,000= 5,000,000

5,000,000* 3,000,000,000 = 1.5*10^16

1.5 is the beginning of your zeros and 10^16 is the zeros after the number

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
