Answer:

General Formulas and Concepts:
<u>Pre-Algebra I</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
- Midpoint Formula:

Step-by-step explanation:
<u>Step 1: Define</u>
R (9, 3)
S (-1, -9)
<u>Step 2: Find midpoint</u>
- Substitute:

- Subtract:

- Divide:

To find the slope you use the slope formula y2-y1 / x2-x1. So use two point on the line we will make ours (1,2) and (3,4). Substitute to make 4-2 / 3-1 = 1/1 so using the rise over run method. The line rises up one and runs by one. The slash mark means divide, it's easiest in a fraction.
Also if you come across the equation y=mx+b, m is the slope and b is the y-intercept, this is called slope intercept formula.
Answer:
6/10 or 3/5
Step-by-step explanation:
4/5 = 8/10
8/10 - 2/10 = 6/10 or 3/5
The answer is 34.05
The total distance (D) is the sum of three distances (d1, d2, and d3).
The distance formula is

Distance 1: Phoenix (–12, –16) to Blythe (–20, –9)<span>:
</span>

Distance 2: Blythe (–20, –9) to Los Angeles (–33, –4):

Distance 3: Los Angeles (–33, –4) to <span>San Francisco (–36, 5)
</span>

<span>
D = d1 + d2 + d3 = 10.63 + 13.93 + 9.49 = 34.05</span>
So, you should add the heighth twice and add the width twice too, then add those two together to get your answer.
