Y=k/x is inverse
y=2
x=8
2=k/8
times 8
16=k
the equation is
y=16/x
second
y=k/x
-3=k/1
-3=k
the equation is y=-3/x
they are
for y=2, x=8 it is y=16/x
and for y-3, x=1 it is y=-3/x
Answer:
y = 3x + 2
Step-by-step explanation:
Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2
So y = 3x + 2
Answer:
300=initial time and 0.05 is the amount of time shaved off of the initial time to run the marathon
Step-by-step explanation:
Answer:
option B : 
Step-by-step explanation:
(a) 
For exponential function , there is no vertical asymptotes
General form of exponential function is
In the given f(x) the value of k =0
So horizontal asymptote is y=0
(b) lets check with option
To find vertical asymptote we set the argument of log =0 and solve for x
Argument of log is x-39
x-39=0 so x=39
Hence vertical asymptote at x=39
