Answer:
The system of equations is
Step-by-step explanation:
Let
x ----> the number of minutes of calling time
y ----> the monthly cost of the calling plan
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
In this problem
Plan A
substitute
----> equation A
Plan B
substitute
----> equation B
therefore
The system of equations is
Answer:
D
Step-by-step explanation:
without knowing anything about the background of the function and what it is used for, I give it the max. possible domain (the set or interval of all possible input values).
and so,
Defined for all m >= 0 and n >= 0.
there is no information provided that would eliminate m = 0 or n = 0.
5^25 = 5 * 25^12 = 5 * 625^6 = 1220703125. Making an even power and squaring the value to divide the power by 2 reduces the time and just enter it in a calculator.
Answer:
The true statement is: one of the factors is (x+2).
