difference is monthly customer fee= 15-10 = $5
difference in minutely charge = 0.08-0.06 = $0.02
minutes it takes for plans to cost same amount= 5÷0.02 = 250 min
I think the answer is D. Her standard deduction went up. Then again i could be wrong hope this helps:)
Since this is a proportion, we cross multiply.
12/2=9/x (The variable "x" is used the represent the unknown number, and this is the number we are solving for)
12*x=2*9 (Cross multiply)
12x=18 (Simplify)
x=18/12 (Divide each side by 12)
x = 3/2 (Simplify fraction)
The unknown number is 3/2, or 1.5.
The parent function, here is
f(x) = x² which is upward opening parabola.
In order to get a graph of f(x) = x²-1, shift the parent function, f(x) = x² by +1 unit downward. This is the transformation.
Answer:
8 x + 3 = 75
9 x - 6 = 75
5 x + 5 = 50
Step-by-step explanation:
8 x + 3
8 (9) + 3
72 + 3
75
---------------------------
9 x - 6
9 (9) - 6
81 - 6
75
---------------------------
5 x + 5
5 (9) + 5
45 + 5
50
