You're trying to find constants
such that
. Equivalently, you're looking for the least-square solution to the following matrix equation.
To solve
, multiply both sides by the transpose of
, which introduces an invertible square matrix on the LHS.
Computing this, you'd find that
which means the first choice is correct.
Answer:
there are 83 percent of books
Well, if 'y' has zeros at x=6 and x=-8,
then 'y' must be the product
y = (x - 6) (x + 8)
Perform the multiplication to get the quadratic function:
y = x² + 2x - 48
A. 10 x <em>d</em>
<em>Explanation </em><em>:</em><em> </em>
1 box has <em>d</em><em> </em>donuts. So that equation would be 1 x d. 10 boxes has <em>d</em> donuts. So that equation would be 10 x d.
