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:
postitive 2 so (0,2)
Step-by-step explanation:
if you were to graph this the slope would be in my case 2/2 so you would go down 2 and over to the left or right 2 dependin gon negitaves.
Given:
At a college, the tuition increased by 10%. Let b be the former cost of tuition.
Use the expression
for the new cost of tuition.
To find:
The equivalent expression by combining like terms.
Solution:
We have,
On combining the like terms, we get
Therefore, the required equivalent expression is 1.10b.
