Answer:
The value of y is 89.55 at x=15 and 60.69 at x=9.
Step-by-step explanation:
The equation of best fit line is
where, y is scores of two students after x working hours.
We need to find the score after 15 and 9 hours.
Substitute x=15 in the given equation.
Substitute x=9 in the given equation.
Therefore, the value of y is 89.55 at x=15 and 60.69 at x=9.
The algebraic expression for the given statement is: 2x² - 3 = y.
<h3>How to Write an Algebraic Expression?</h3>
To wrote an algebraic expression is translate a statement using numbers, variables, and mathematical sign into a mathematical statement.
Square of x is: x²
Product of x² and 2 is: 2x²
Thus, we would have:
2x² - 3 = y
The algebraic expression is: 2x² - 3 = y.

Answer:4x2−6x−4
Step-by-step explanation:
(4x+2)(x−2)
=(4x+2)(x+−2)
=(4x)(x)+(4x)(−2)+(2)(x)+(2)(−2)
=4x2−8x+2x−4
=4x2−6x−4
