Which of the following is equal to the rational expression when x*-2 or 3?
1 answer:
The value of the expression in the simplified form is f(x) = x+3/x-3
<h3>Rational expression</h3>Rational expressions are expressions written as a ratio of two integers or expressions.
Given the rational expression below;
f(x) = x²+5x+6/x²-x-6
Factorize the numerator and denominator
f(x) = x²+3x+2x+6/x²-3x+2x-6
f(x) = x(x+3)+2(x+3)/x(x-3)+2(x-3)
f(x) = (x+3)(x+2)/(x+2)(x-3)
f(x) = x+3/x-3
Hence the value of the expression in the simplified form is f(x) = x+3/x-3

Answer:
Number line A.
Step-by-step explanation:
The first number line A, represents x > 7, which the unshaded circle starting from 7 and moving to the right.
Number line B represents x < 7 with the direction being to the left (opposite of A).
Number line C is synonymous with A, however the starting point is shaded which represents x ≥ 7
Number line D also follows up from B with D representing x ≤ 7
The ODE appears to be
It's separable; we can write
and integrating both sides yields
