W = 17/13.
I hope this helps. I'm pretty sure I got it wrong, but just let me know.
Answer:
x = 2
Step-by-step explanation:
Given 2 secants intersecting a circle from an external point, then
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20
Subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Answer:
15=24
20=x
cross multiply
15x=24*20
15x=480
divide both sides by 15
x=480/15
x=32
it will take her 32 minutes
To find a vertical asymptote set the denominator = to zero.
x + 2 = 0
x = -2
The vertical asymptote is at x= -2
