Steve and Sally went canoeing on Red river on a day when the current flowed at 3mi/h. They left at 8:30 A.M and paddled upstream until they reached Elk Island, where they stopped to have lunch. After...

this is a rational function question that deals with direct variation.

Suppose x and y vary inversely, and y = 10 when x = 4. Write a function that models the variation (1pt.). Then find y when x = 90 (1pt.). Thank you

Been trying to solve these 2 but have been struggling with it. Here they are: 1.) (3x)/(2(x+9)) + (x-4)/(x+3) -------------Simplify the expression. 2.)(x-7)/(x^2-8x+15)...

I know that you can solve for the x intercept by solving the numerator, but when I did that and got 2, it said the correct answer was that there was no x intercept. Can someone explain this...

We're solving rational equations and we get extra credit if we have this problem answered by tomorrow! x+5/x^2-6x-27+x-17/x^2-18x+77=x+1/x^2-14x+33 Please...

I just need to know what the range of this equation is.

For what values of b does the function 1(x)= 1/2x^2-bx+7-2b have no vertical asymptotes

Find a rational function with the following properties (there is more than one possible answer): • vertical asymptote: x = 1 • horizontal asymptote: y = −2 • hole: x=−1 • x-intercept: (3,0)

f(x) = (3x) / (x2 + 1). Show that f-1(x) = (6 - 3x2) / (x2 + 2)2

f(x) = (2x-2)/ x2+x-2 g(x) = a/ b+x

When a liquid is placed into a refrigerator, its temperature T°C at a time t minutes is given by the formula T=T*10^-kt The temperature is initially 100°C and drops to 40°C in 5 minutes. Find...

Find a rational function that represents a graph that has a vertical asymptote at x=2 and x= -3 and a horizontal azymptote at y=0. the answer is f(x)= (x-4)/(x2+x-6) I...

given f(x)= t3-2t2-8t/t2-4 find the domain, asymptotes, holes and intercepts. I know that to find the x intercept you set y=0 and solve for x but I am unsure how to isolate x...

Need this to graph please have no idea , need all intercepts, asymptotes and domain

F(x)=3x(x-2)/6x^2-41x-7

An airplane makes a 990-mi flight with a tail wind and returns, flying into the wind. The total flying time is 3h 20min, and the plane's airspeed is 600mph. What is the wind speed?

Vertical Asymptote at x=-2 Horizontal Asymptote at y=1 X-Intercepts: (-3,0) and (1,0) Y-Intercept: (0, -¾)
