Yea 4/16 is equivalent to 0.25
Information : The given hyperbola is a horizontal hylerbola with its centre (3 , -5) and one of its focus at (9 , -5) and vertex at (7 , -5) and as we can see that the focus and vertex have same y - coordinates, it must have its Transverse axis on line y = - 5.
Now,
it's vertex is given, I.e (7 , -5)
so, length of semi transverse axis will be equal to distance of vertex from centre, i.e
Now, it's focus can be represented as ;

so,
and we know, a = 4



Now, let's find the measure of semi - conjugate axis (b)






So, it's time to write the equation of hyperbola, as we already have the values of a and b ~

[ plug in the values, and h = x - coordinate of centre, and k = y - coordinate of centre ]

You are right! 6 2/3 is the answer
Step-by-step explanation:
10+3(x+2)=36
10+3x+6=36
16+3x=36
3x= 20
x=6 2/3
What are you looking for because you can not simplify those
Would it be two equilateral triangles?
I'm sorry if this doesn't help I don't really know what type of triangle that is.
