Choice C (0.50g + 8 < 20).

Step-by-step explanation:

1) From this context nothing more than $20 must be spent.

Mathematically it is < 20 (less than or greater than 20)

2) Each game cost $0.50.

Let g = any number of game(s)

The cost of any number of game(s) = (0.50 × g) = 0.50g.

3) Expenses must include paying for admission into the carnival and paying for the game. Irwin Altman MS 172 can only spend less than or equal to $20 at the carnival.

Since cost of playing the game(s) = 0.50g ( its already calculated at (2))

And the cost of paying for admission = $8

Expenses (Mathematically) = 0.50g + 8

4) the whole statement is Mathematically written in terms of inequality as:

0.50g + 8 < 20 which means expenses must be less than or equal to $20 to play a game at the carnival.

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.

this is a subtraction problem.

10 - 2 = 8
