Answer:
-3
Step-by-step explanation:
Select a point on the red line that crosses the graph at a corner like point (2,2). Start at the middle of the graph and go 2 spaces to the right on the x axis and then 2 spaces up. Now you will be a the point (2,2). Do you see how the right line is hitting at the top left corner of the square?
From this point, count how many spaces up and how many spaces to the left to get to the next spot that the red line touches a corner. If you go up 3 spaces and left 1, you have found the next corner. The slope is -3/1 or -3.
The slope is negative because the x and y's are going in different directions, as the x is getting bigger, the why is getting smaller, or another way of looking at it, is that I went up to the find slope and up is positive, but then I went left 1 and left is toward the negative numbers. A positive divided by a negative is a negative, so the slope is negative.
1/2 is the largest fraction out of all of them
Answer:
$16,748
Step-by-step explanation:
we know that
The equation of a exponential decay function is equal to
where
y is the value of the car
x is the number of years
a is the initial value
r is the rate of change
In this problem we have
substitute
For x=3 years
substitute
The remainder theorem says that if
is a factor of a polynomial
, then the remainder upon dividing
is 0 so that there exists a lower degree polynomial
as the quotient:
Using the fact that
is a factor, you can find a quadratic
which is easy to factorize further.
Synthetic division yields
which can be factored further as
So,
The roots are then
.

Devon made a scale drawing of a triangle. He used a scale factor of 1/4 to draw the new triangle. How does each side of the new triangle compare to the original? Each side of the new triangle is 4 times shorter than the original.
