(g-f)(x) is x² - 3x - 6
<u>Step-by-step explanation:</u>
Step 1:
Given g(x) = x² - 1 - 2x, f(x) = x + 5. Find (g-f)(x)
(g-f)(x) = x² - 2x - 1 - (x + 5) = x² - 2x - 1 - x - 5 = x² - 3x - 6
For this case we have an exponential equation of the form:

Where,
- <em>A: initial value
</em>
- <em>b: decrease rate
</em>
- <em>x: number of years
</em>
Substituting values in the given equation we have:

Answer:
The value of the car after 15 days is given by:

Answer:
D. similar; proportional; congruent
Step-by-step explanation:
Any pair of figures is similar if their corresponding sides are proportional and their corresponding angles are congruent. That is the meaning of <em>similarity</em>.
Answer:
The sum of the squared residuals
Step-by-step explanation:
If you sum the residuals, you would get 0
if you sum of the absolute values of the residuals you wouldn't be doing "least-squares regression"
The influence of outliers D The slope is another metric that has nothing to do in creating the regression line
From largest to smallest:
3 hundreds (300) , 6 tens (60) , 8 ones (8)
