The slope intercept form is y=mx+b
in this case y=-x
y=(-1)x + 0
so the slope m=-1 and y-intercept which is b is 0
3 ÷ 2 = 1.5
So each student had a pack and a half.
Hope this helps. :)
He answer to this question is:A. The length is 8 inches, and the width is 5 inches.
The scale factor can be found in the question, "the art team made a scale drawing of the top of the box using a scale of 3 inches to 1 inch". This means the scale drawing should be divided by a scale factor of 3:1 (simplified into 3).
The scale factor is then divided with the components provided (24 inches in length, 15 inches in width).
(24/3) = 8 inches(15/3) = 5 inches
Your answer is length = 8 inches, width = 5 inches.

From the given starting values, we have
and more generally, the
-th term pair is captured by
so that
We notice that
which is to say that the explicit formula for
is given by the dot product of the second row of
with
.
First we diagonalize
. It has eigenvalues
, where
with corresponding eigenvectors
, where
Then we have
where
is the matrix whose columns are
and
and
is the diagonal matrix whose non-zero entries are the eigenvalues of
. So
which gives
From here, you would just need to determine the bottom row of the final matrix product.
Answer : Always A negative number raised to an odd power is always negative. When a negative number is raised to an even power, the pairs of negatives will cancel out; but when it is raised to an odd power, after pairs of the negative sign have canceled each other out, there will still be one minus sign left unpaired, which will not cancel out.
