Using the equation below as a model, fill in numbers in the place of a and b to create a rational equation that has an extraneou
s solution.
x plus a over ax = b over x
Part 1. Show all work to solve for x in the equation and check the solution.
Part 2. Explain how to identify the extraneous solution and what it means.
1 answer:
Lets solve the equation step by step:
(x + a)/ax = b/x
therefore: a != 0, x !=0
now we solve:
<span>(x + a)/ax = b/x
</span><span>(x + a)/a = b
</span>x + a = ab
x = a(b - 1)
that is the solution for b, and we keep in mind that <span>a != 0, x !=0, the extraneous solutions
</span>

count to 69 and you got 12 lay ups
The answer is A because if we stare with (-1,3) and go up by 1x, since the slope is 2, then 3 + 2 is 5 and we have (0,5). Hope this helps!
