What causes a solution to a rational equation to be an extraneous solution?
a) when there is more than one solution, one of the solutions is extraneous.
b) if a solution results in zero when substituted into the denominator of the equation, the solution is extraneous.
c) if a solution results in a negative number when substituted into the denominator of the equation, the solution is extraneous.
d) when a solution is a fraction, the solution is extraneous.

Step-by-step explanation:

An extraneous solution is a solution that emerges from the problem, but it's not actually a solution because it doesn't make sense to the problem.

The best example of this is when we get a solution in a rational expression which becomes the denominator zero. That's an extraneous solution because it doesn't make sense, since the number zero can't divide a number.

Therefore, the right answer is B.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
