Functions can be represented on graphs
The value of f(k + 3) is 0
Given that:
From the graph, we have:
So, by comparison:
Substitute 2 for k in f(k + 3)
From the graph, f(5) = 0
So, we have:
Hence, the value of f(k + 3) is 0

Answer:
Step-by-step explanation:
Let
x------> the number of books
we know that
The linear equation that represent this situation is equal to
solve for x
Divide by 
both sides
As a fraction it would be 388888/100000.
1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is
, so in this case, it is
, which comes to
. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=
x-
.
2. Use the same process as in question 1 to find:
y=-7x+11
Take 1000 divided by 70 and you get 14.586
