Step-by-step explanation:
<u>Step 1: Define</u>
R(x) = 6x - 3
S(x) = -3x - 8
<u>Step 2: Find</u>
- Substitute in functions: R(x) - S(x) = 6x - 3 - (-3x - 8)
- [Distributive Property] Distribute negative: R(x) - S(x) = 6x - 3 + 3x + 8
- [Addition] Combine like terms: R(x) - S(x) = 9x + 5
If there are outliers, IQR is a better measure of the spread of data than range. The range will include the outliers, and make the data appear to have many more terms of a greater/lesser value than it has in reality. IQR shows the middle 50%, which (usually) doesn't contain outliers, so the majority of the data spread would be shown by IQR in a data sample with a significant amount of outliers. If your measure of the spread of data contains outliers, then the measure isn't accurate.
Answer:
y = 3x -2
Step-by-step explanation:
If the line is parallel, that means it has the same slope. The given equation had a slope of 3, so the new line must also have a slope of 3.
You can plug the given coordinates into the slope-intercept form with a slope of 3 to find your answer.
y = m*x + b
7 = 3*3 + b
7 = 9 + b
-2 = b
y = 3x -2
I Hope This Helps :D

110-108 =2
By weeks 6 she will only have $2 left
So being realistic, at week 7 she will have spent all her money.
