2. Simplify. -4(12-2) + 13 * Your answer

-27 is your answer :)

have a good day <3

-27

Step-by-step explanation:

1. Foil

-4(12-2) +13 = -48 - (-8) +13

2. Add the opposites

-48 -(-8) +13 = -48 + 8 +13

-48 +8 +13 = -27

-27

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.
