Answer:
All of them.
Step-by-step explanation:
For rational functions, the domain is all real numbers <em>except</em> for the zeros of the denominator.
Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:
Zero Product Property:
Solve for the x in each of the three equations. The first one is already solved. Thus:
Thus, the values that <em>cannot</em> be in the domain of the rational function is:
Click all the options.

Answer:
16.5 hours
Step-by-step explanation:
The bicycle costs $240. Eva already has $42. She is making $12 per hour.
240 = 12x + 42
Solve for x to find out how many hours Eva needs to work to buy the bicycle.
240 = 12x + 42
240 - 42 = (12x + 42) - 42
198 = 12x
198/12 = (12x)/12
16.5 = x
Eva needs to work 16.5 hours to be able to buy the bikw.
Answer:
What was the problem?
Step-by-step explanation:
Oh ok , I G u e s s it is solved already.
"Let There Be a Gas Phase"
There, a type of material called kimberlite magma causes the solid rock to break its way up from deeper into the mantle of Earth. The magma gathers fragments of rocks as it rises, like floodwaters gathering up silt and gravel. Diamonds are contained in some of these fragments.
