What are the solutions of the rational equation?

x=25

Step-by-step explanation:

First, multiply everything by five. You get x+6 = 2x-4 - 15

Then just solve for x.

x+21=2x-4

x+25=2x

25=x

Gotta check this, though.

x+6/5 = 2(25)-4/5 - 3

31 = 50-4 - 15

31 = 31

And you're good to go!

Btw, this isn't a true rational equation because there's no x in the denominator.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
