A giant box has the dimensions of 1.5m x 0.75m x 0.6m. It stores smaller boxes with
dimensions of 5cm x 3cm x 4cm. If each
smaller box weighs 500g, and the big box
weighs 6000 kg when it is full, how much does
it weigh when it is empty?

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

for every positive x value, the y value must be greater than 1.

for every negative x value, the y value must be less than 1.

in your options, you can check to see that one of these two criteria is met. if neither are met, then it is not on a slope with positive line.
