General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Slope Formula: 
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Point (4, 15)
Point (-1, -15)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute:

- Subtract:

- Divide:
<u>Step 3: Find y-intercept </u><em><u>b</u></em>
- Define: y = 6x + b
- Substitute: -15 = 6(-1) + b
- Multiply: -15 = -6 + b
- Isolate <em>b</em>: -9 = b
- Rewrite: b = -9
<u>Step 4: Write linear equation</u>
<em>Substitute in all variables.</em>
y = 6x - 9
And we have our answer!
2L + 2W = 62
2(20) + 2W=62
40+ 2W=62
62-40=22
2W=22
22 divided by 2 is 11
W= 11
Answer:
Z=0.75
Step-by-step explanation:
Given
Z is inversely proportional to X.
First we’ll define what an inverse proportion is. Inverse proportion is a relationship between two quantities such that if one quantity increases the other decreases.
Symbolically the relationship between Z and X can be defines as
Z ∝ 1/X
When the proportionality symbol is removed a constant is introduced.
Z= K/X
As we Know,
X=16
Z=1.125
We can find the value of K by using the values of Z and X
Putting in the values
1.125=K/16
K=1.125*16
K=18
Now, For
X=24
Z= 18/24
Z=0.75
