Answer:
$C = 0.30(m) + 15
C is bill cost
m is number of minutes used
Step-by-step explanation:
In this question, we are asked to write an equation that estimates the bill cost of Maggie’s phone bills.
We proceed as follows;
Now, let’s try and find the base fee.
We can calculate this using her bill for September.
Mathematically;
Bill = (Cost per minute * total minutes) + Base fee
Here, $0.30 per minute for 120 minutes will yield a total of 120 * 0.3 = $36
This means the base fee would be $51-$36 = $15
Now let’s say the bill is $C, and the number of minutes used is m
Mathematically;
$C = 0.30(m) + 15
Answer:
y= ½x+9

Step-by-step explanation:
the answer to your question with roster method is
(-5,-4,-3,-2 and -1)
What form do you need it in?
First we put the equation in y = mx + b form where m is ur slope and b is ur y int.
2x - 5y = 10
-5y = -2x + 10
y = 2/5x - 2.......so ur slope is 2/5 and ur y int is (0,-2) <==
to find ur x int, sub in 0 for y and solve for x
2x - 5y = 10
2x - 5(0) = 10
2x = 10
x = 10/2
x = 5......and ur x int is (5,0) <==
another way to find the y int is to sub in 0 for x and solve for y...but u might as well solve it by putting it in y = mx + b form because that way u have ur slope as well.
