Answer:
E.
simple random sample
Step-by-step explanation:
The slope of the linear equation, 
, is: 
<em><u>Recall:</u></em>
- A linear equation in slope-intercept form is given as: <em>y = mx + b.</em>
- "m" is the slope.
- "b" is the y-intercept.
Thus, given the linear equation:
,
C represents y
m represents x
represents the slope (m)
22.5 represents b.
Therefore, the slope of the linear equation, , is:

Step-by-step explanation:
<u>Step 1: Define</u>
P(x) = x³ + 4x² - 3x + 1
P(1) is x = 1
P(-2) is x = -2
<u>Step 2: Evaluate</u>
<em>P(1)</em>
- Substitute: P(1) = 1³ + 4(1)² - 3(1) + 1
- Exponents: P(1) = 1 + 4(1) - 3(1) + 1
- Multiply: P(1) = 1 + 4 - 3 + 1
- Add: P(1) = 5 - 3 + 1
- Subtract: P(1) = 2 + 1
- Add: P(1) = 3
<em>P(-2)</em>
- Substitute: P(-2) = (-2)³ + 4(-2)² - 3(-2) + 1
- Exponents: P(-2) = -8 + 4(4) - 3(-2) + 1
- Multiply: P(-2) = -8 + 16 + 6 + 1
- Add: P(-2) = 8 + 6 + 1
- Add: P(-2) = 14 + 1
- Add: P(-2) = 15
Answer:any number is correct
Step-by-step explanation:
4(3x+1)=12x+4
12x+4=12x+4
12x-12x=4-4
0=0
This equation has no answer.
Actually any number you put in place of x this equation will be true so we can say the answer is
X=infinity
