Here the only limitation on the domain exists when the denominator is equal to zero, as division by zero has no meaning and is not "allowed" because of its meaninglessness. :)
Factor the denominator to find the excluded values of x...
3x^2+5x-12
3x^2+9x-4x-12
3x(x+3)-4(x+3)
(3x-4)(x+3)
So x CANNOT equal 4/3 or -3 (all other real values of x are part of the domain) so the domain is:
x=(-oo, -3),(-3, 4/3),(4/3, +oo)
Answer:
just add 2.5 to Lin's distance and 3 to Andre's distance. eventually you will reach a point where their values are the same. Then the hour next to it is the answer you are looking for
Step-by-step explanation:
Answer:
The answer is
Step-by-step explanation:
We must find a solution where
Consider the Left Side:
First, to add fraction multiply each fraction on the left by it corresponding denomiator and we should get
Which equals
Add the fractions
Simplify the right side by multiplying the fraction
Set both fractions equal to each other
Since the denomiator are equal, we must set the numerator equal to each other
