If one item cost $0.75 and I paid $2.25 at the register, how many items did I buy?

3

Work: This is simple division, I just did $2.25 divided by $0.75, and I received the answer 3.

I hope this helps, and Happy Holidays! :)

You bought 3 items.

Step-by-step explanation:

All we have to do is multiply $0.75, the amount of the cost of the item, by the amount that you paid.

So:

0.75 × 2.25 = 3

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
