F(x)=5/x
g(x)=2(x^2)+5x
f(x) has a domain of all real numbers excluding zero
g(x) has a domain of all real numbers
fog(x)=5/(2(x^2)+5x)
fog(x)=5/(x(2x+5))
fog(x) has a domain that excludes both zero and -5/2
Initial balance, I = $2376.10 .
Total amount of purchase made, A = $( 875.22+65.75+45.22+21.23 ) = $1007.42 .
Total amount credit, c = $875.22 .
Fine, f = $45.30 .
Another purchase, 
.
So, balance left is :
B = I - A - f - a + c
B = 2376.10 - 1007.42 - 45.30 - 59.4025 + 875.22
B = $2139.1975
Hence, this is the required solution.
Answer:
question seems incomplete but with the limited information one can deduce that the professor was trying to investigate how students CGPA is affected by the length of period spent on video games.
A
Step-by-step exp
independent variables are constants. they do not change or depend on any other variable.
dependent variables, they do depend on other variables, we call them resulting variables..
<span>-6x-3y=18
Substitute 0 for y
-6x-3(0)=18
Multply -3 by 0
-6x=18
Divide both sides by -6 so that the only thing on the left side is the variable x.
Final Answer: x= -3</span>
