-1. Plug in -3 for x which makes 9-10 so -1
Answer:
The first option
Step-by-step explanation:
The domain of a rational function should be all real numbers except for when the denominator is equal to 0. To find when the denominator is equal to 0 you simply need to find the zeroes of the denominator... but in this case you can do that through factoring and using the quadratic equation.
So first step is going to be to factor out the GCF, which in this case is x. This gives you the equation. 
. So one of the zeroes is when x=0. Now to find the other two zeroes you can use the quadratic equation which is 
. So to find the other zeroes you simply plug the values in. a=2, b=-1, c=-15
Answer:
$33
Step-by-step explanation:
From the question, $22 is correct
If Helen Ming receives travel allowance of $220 from her company for time away from home
She has a 10% income tax rate
The amount she has to pay in taxes for the employee benefits is
10% of $220
10/100*$220
=0.1*$220
=$22
So you are correct
The only reason why you could be wrong is if the question is different from what you posted above just like the below question
Helen Ming receives a travel allowance of $220 each week from her company for time away from home. If this allowance is taxable and she has a 15 percent income tax rate, what amount will she have to pay in taxes for this employee benefit?
Here the amount she has to pay for the employee benefits is
15% of $220
15/100*$220
=0.15*$220
=$33
The more digits you have the bigger the number, unless you have a long decimal, and in that case only is the number smaller in value.
