Answer:
if youre answer has to be a whole number it would be 3 otherwise it would be x<4 ( so anything less than 4 )
Step-by-step explanation:
so because we are trying to find which company is less, we need to set up in inequality.
so first lets do company A
because 15 is our reoccuring fee, its going to be the coeifficient
so the equation would be
A - 15x + 20
now lets do company B
because it only 20 every month we dont need to have a constant which means the equation for B would be
B - 20x
so lets put it all together
15x + 20 > 20x ( remember our B side has to be less )
now lets solve it
20 > 5x
we know that if x = 4 then the two would be equal, which means our answer would have to be 3 months.
now always check your work.
15 (3) + 20 = 65
20(3) = 60

Answer:
1. B 2. C
Step-by-step explanation:
1. x^2-18x+(18/2)^2=19+(18/2)^2
(x-18/2)^2=100
(x-9)^2=100
x1= -1 x2= 19
2. x^2=81
x=+-9
x1=-9 x2=9
