Answer:
The constant in the expression is 12
Step-by-step explanation:
The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can be written as :
f(m)=0.05m +12
Example if m is 1 or 2
f(1) = 0.05(1) +12 = 12.05
f(2= = 0.05*2 +12 =0.1 +12 = 12.1
The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.
an =a1+d(n-1)
where d is the common difference
d=5-8
d=-3
a1=8
an =8-3(n-1)
Choice C
To make a perfect square, we must know that 22/2 = 11. In this case:
(x + 11)^2 = x^2 + 22x + 121
20.31 is the same as 20.310
So, 20.301 is less than 20.310
I got 35 hours. You can solve by doing 10x+125=7x+230.
