We need to find the probability of the card chosen at random is yellow or brown.
So, since there are 3 yellow cards and 7 brown cards, the total numbers of cards that are yellow or brown is:

Now, the probability that the chosen card is yellow or brown can be found by dividing the above value by the total number of cards in the box.
The total number of cards in the box is:

Thus, that probability is given by:

Therefore, the answer is:
Answer:
-6y = 70x = 3
Step-by-step explanation:
-6x - 5y= 64x+ y=3
---------------------------
-y - y
---------------------------------
-6x -6y = 64x = 3
------------------------------------
+6x +6x
-------------------------------------
-6y = 70x = 3
Easy
quadratic means 2nd degree
means highest power of exponent is 2
so like x^2
first one
we have 3x^3, that is 3rd degree,nope
2nd one
we have 8x^4, nope, that is 4th degree
3rd one
we have -x^2, yep
4th one, we have 9x^4, that is 4th degree
answer is 3rd one or p(x)=-5x-x^2
Answer:
yes it is because they are both going by two
