Answer:
20 pi is the correct answer
Answer:
Sonya pays a flat fee of $30 for her phone bill and pays $2 per gigabyte she uses per month. Put Sonya's bill as an equation with <em>d</em> being how many gigabytes she uses per month.
Step-by-step explanation:
We get the flat fee of $30 from "30 + 2d" and the $2 per gigabyte from "30 + 2d" and since we want to find out Sonya's total bill, that's where the + in "30 + 2d" comes from. We want the variable to be <em>d</em> therefore <em>d</em> is how many gigabytes she uses per month.
Answer:
The answer would be division (B)
Step-by-step explanation:
4x equals the total amount
x equals the cost of one item
Therefore you'd divide total cost by 4 and that would find the cost of one item
Answer:
-10x + 1.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, we can find the slope using the slope equation and two of the points.
Slope equation:
I'm going to use the first two points just so I can avoid the fraction... Substitute the x and y values into the equation.
Simplify:
Now that we have the slope, all we need is the y-intercept. Luckily, it gives it to us in the table. The x value of y-intercepts will always be 0. Looking at the table, we see that the point where x=0 is (0,2). Thus, the y-intercept is 2. Your final equation is
