Answer:
5x+2
Step-by-step explanation:
(9x+5)-(4x+3)
5x+2
Step 3:
14/7x-6/3=5
2x-2=5
2x=5+2
2x=7
x=7/2
I think the answer would be 4n
Answer:
The domain is 
The range is 
Step-by-step explanation:
we have

<em>Find the domain</em>
Remember that
The domain of a function is the set of all possible values of x
we know that the radicand of the function must be greater than or equal to zero
so

solve for x

therefore
The domain is 
<em>Find the range</em>
Remember that
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
For x=7
The value of y is equal to

so
The solution for y is the interval [1,∞)
therefore
The range is
