Answer:
The initial value is 4 and the rate of change is tex]\frac{-3}{4}[/tex]
Step-by-step explanation:
The initial value is the y intercept of the given line.
Y intercept is the point where the graph crosses y axis
y intercept is (0,4) so initial value is 4
Rate of change is the slope
To find rate of change we use formula
Pick two points from the graph
(0,4) and (4,1)
Rate of change =

Answer:
<u>900</u> black and white copies are printed.
Step-by-step explanation:
Given:
For every 9 black and white copies printed there are 2 color copies printed.
If there are 200 color copies printed.
Now, to find the number of black and white copies are printed.
Let the number of black and white copies printed be
As given, for every 9 black and white copies printed there are 2 color copies printed.
So, 9 is equivalent to 2.
If there are 200 color copies printed.
Thus, is equivalent to 200.
Now, to solve by using cross multiplication method:
<em>By cross multiplying we get:</em>
<em>Dividing both sides by 2 we get:</em>
Therefore, 900 black and white copies are printed.
