I need this fast please i will try to mark brainliest

Step-by-step explanation:

we have to find if the series have a constant of proportionality by dividing the value of y by each value of x

1)

100 : 2 = 50

200 : 4 = 50

300 : 6 = 50

400 : 8 = 50

ok = y

2)

0.60 : 4 = 0.15

1.20 : 8 = 0.15

1.44 : 12 = 0.12

no = n

3)

0.15 : 1 = 0.15

0.3 : 2 = 0.15

0.45 : 3 = 0.15

0.6 : 4 = 0.15

ok = y

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
