Answer:
Step-by-step explanation:
Given : There are six balls in bag
Basketballs=2
Playground balls =3
Soccer ball =1
To Find : the probability that if you pick one of the balls without looking, it will be a soccer ball
Solution :
Total no. of balls = 6
No. of soccer balls = 1
Probability = favorable outcomes / total outcomes
Since total outcomes = total no. of balls =6
And favorable outcome = no. of soccer balls = 1
Thus , Probability of getting soccer ball = 
Hence the probability that if you pick one of the balls without looking, it will be a soccer ball:
The process is similar to (and easier* than) adding three 4-digit numbers. Add the numbers in each column.
The sum is ...
(2+1-3)x³ +(-4+6+2)x² +(6-8-4)x +(-3+12-7)
= 0x³ +4x² -6x +2
The sum is 4x² -6x +2
_____
* The process is easier because there are no "carry" operations from one column to another as there may be when adding multi-digit numbers.
Answer:
Step-by-step explanation:
5c^5-c+c^5+7c-2
add like terms
=6c^5-c+7c-2
subtract like terms
=6c^5+6c-2
=2(3c^5+3c-1)

Becasue you dont need too much.
Answer : Focus (4,4) , directrix x=10
Given equation is
The given equation is in the form of
Where vertex is (h,k)
h = 7 and k = 4 so vertex is (7,4)
4p = -12 so p = -3
Focus is (h+p, k)
h=7, k=4 and p = -3
focus is (7-3, 4) that is (4,4)
now we find directrix
Directrix x= h-p
So x= 7-(-3)= 10
Focus (4,4) , directrix x=10
