Answer: $612.65, $2,567.45, and increase
Step-by-step explanation:
Answer:
0.00118063754
is right...
Step-by-step explanation:
The answer would be a because it says to write two equations to support your answer
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
Answer:C =$65 + $30G
Step-by-step explanation:
Given that :
Base fee charge = $65
Overage charge = $30 / per gigabyte for data that exceeds 2 gigabyte
C = cost ; G = total amount of gigabyte
Equation to represent plan; if more than 2 gigabyte are used :
Cost (C) = Base charge + (average charge * amount of gigabyte)
C = $65 + ($30 * G)
C =$65 + $30G
