Let Length of each Plan A workout be
and Length of each Plan B workout be $b$
on Wednesday,
$5a+3b=7$
$2a+12b=19$
multiply equation one by $4$ and subtract equation two from it
to get,
$18a=9$ or $a=\frac12$
substitute $a$ in eq 2. to get $b$, $12b=18\implies b=\frac32$
Answer:
Step-by-step explanation:
Given:
Vertices of Hyperbola : (0 ± 6) or (0,6) and (0,-6)
and asymptotes at y= (±3/5)x 0r y= 3/5 x and y=-3/5 x
The vertices are of vertical hyperbola. The equation used will be:
The Center of hyperbola (h,k) =(0,0)
The Distance from vertices to center is a and a = 6 (given)
For equation we have value of h,k and a and need to find value of b
we know,
y= k ± a/b (x-h)
Values of h and k are zero
y= 0 ± a/b (x-0)
y= (± a/b ) x
We are given asymtotes at y= (± 3/5)x which is equal to y= (± a/b ) x
as a = 6 then b= 10 i.e The simplified form of 6/10 is 3/5 so value of b=10
Putting values of a,b,h and k in equation we get,
