Since the graph is a straight line, its equation is of the form;

Where m is the slope and c is the y intercept
We can use any two points on the straight line to find the value of m and c.
Let us use (0,30) and (4,150)

This simplifies to,

Let us substitute the value of m to obtain,

Substitute any of the points to find c. It is easier to use (0,30).


The equation of the graph now becomes,

So in 10 weeks Ben will collect,



Ben will collect 330 papers.
You can also use any two points to find the equation of this line.
Answer:
n=R
Step-by-step explanation:
f(n)=9n+1
Answer:
f(-2) = -1
Step-by-step explanation:
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1
Answer:
Step-by-step explanation:
The area of a regular polygon is
where a is the apothem and p is the perimeter. Perimeter is simple: just count the number of sides the polygon has and multiply it by 3 (the length of one side).
p = 3(9) is 27 inches for the perimeter.
We have what we need now to find the area:
and
so
A = 55.35 square inches
