Devin is collecting signatures for a petition to open a new park in her town. she needs to collect at least 1,000 signatures before she can schedule a meeting with the mayor. she already has 380 signatures. if each petition page holds 80 signatures, which inequality best shows how many more pages (p) devin needs?

up

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.

your answer would be 10x - 1
