4+9=13
Step-by-step explanation:
x=4
2(4)+1=y=9
4+9=13
when you subtract a negative number from any platitude number the equation changes to addition so you would add the value of the negative number to 1.
Answer:
27 is 80% of 33.75
Step-by-step explanation:
Given :
The foci of hyperbola are (8,0) and (-8,0) .
The difference of the focal radii = 6.
To Find :
The equation of the hyperbola.
Solution :
We know, distance between foci is given by :
2c = 8 - (-8)
c = 8
Also, difference between the foci or focal distance is given by :
2a = 6
a = 3
Now, we know for hyperbola :

General equation of hyperbola is :

Hence, this is the required solution.
