the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.
when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.
-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
Answer from: Quest
answer: a) (0,0), (1,1), (2,8), and (3,27).
step-by-step explanation:
0^3=0
1^3=1
2^3=8
3^3=27
in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
Answer from: Quest
In this problem it decreased 20%
