It seems confusing, but it's just breaking down the steps for you. It's done the same as any other word problem.
a. The unknown is how many minutes she used beyond the plan. So, we'll use "m" for the variable, to represent minutes.
b. 73.40 = 65 + 0.10m
The 73.40 is the total, which is why it's by itself. 65 represents the price per month for the plan, and 0.10m is the price per extra minute multiplied by the unknown amount of minutes used.
c. 73.40 = 65 + 0.10m
8.40 = 0.10m
84 = m
d. The number of minutes that Allegra went over the time that the plan allows is found by solving the equation we just wrote and solved. $0.10 is paid for every minute past the plan's allowance, meaning that "m" in the equation, when solved, shows us exactly how many minutes over Allegra went.
Since the equation says "cos(x-2)", we know that the horizontal displacement is 2 units.
Answer:
−5x+13y=84
Step-by-step explanation:
I hope this is good :)
The only answer would be A because if you divide it by 20 it should divide it equally i tried the other ones and they didnt work
Answer:
i can only explain it. sorry. if u need help ask
Step-by-step explanation:
so u gotta find a, b, and c.
the first part of a is going to equal x, the other is y(u know what i mean?)
so it says that a= -2, -1. So -2 is the x and -1 is the y.
y= rise/run.
thex=run, and the rise =y.
