Answer:
f(x) = (x - 4)² - 13
Step-by-step explanation:
Given
f(x) = x² - 8x + 3
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
f(x) = x² + 2(- 4)x + 16 - 16 + 3 = (x - 4)² - 13
Using a linear function, it is found that the estimated French score is of 38.1875.
A <em>linear function</em> has the following format:

In which:
Searching the problem on the internet, it is found that two points of the line of best-fit are: (10,65) and (90,26).
The slope is given by <u>change in the output divided by the change in the input</u>, hence:

Then:

Point (10,65) means that when
, and this is used to find b.



Hence:

For a student who got 65 in math, x = 65, and hence:

The estimated French score is of 38.1875.

Answer:
The correct answer is B. Mark the points of intersection between the three circles.
Answer:
1
Step-by-step explanation:
Slope = y2 - y1 / x2 - x1 so, (0 - (-2)) / (1 - (-1)) == 2/2 = 1
