Step-by-step explanation:
so first you graph the triangle
count how many units one point is from the other point
and if it's hard to count the units (maybe bc the line is diagonal) use the distance formula or the Pythagorean theorem
Step 2 I believe. You are supposed to find the absolute value before adding
If you would like to solve - 3 * a^2 - b^3 + 3 * c^2 - 2 * b^3, if a = 2, b = -1, c = 3, you can calculate this using the following steps:
a = 2, b = -1, c = 3
- 3 * a^2 - b^3 + 3 * c^2 - 2 * b^3 = - 3 * 2^2 - (-1)^3 + 3 * 3^2 - 2 * (-1)^3 = - 3 * 4 - (-1) + 3 * 9 - 2 * (-1) = - 12 + 1 + 27 + 2 = 18
The correct result would be 18.
Answer: He should have used the mean to determine the average because the data sets are approximately symmetric.
Step-by-step explanation
Using the inequality
2.50x + 3.50y ≤ 30
substituting y with the number of cheeseburgers sold
2.5x + 3.5(4) ≤ 30
x = 6.4
The maximum number of hamburgers he can sell is 6
