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:
y = (x - 2)² + 9
Step-by-step explanation:
To obtain the equation in vertex form use the method of completing the square.
Add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 + 13
= (x - 2)² + 9 ← in vertex form
Answer:
D. 0.343
Step-by-step explanation:
You can see the first three options as 0.340 so if you substract this number with 0.343 the remainder is positive 3.
This strategy also can be applied to the number 0.3409 but in this occasion the result is different:

That is small number but still is positive that's meaning that between 0.343 and 0.3409 the greatest value is 0.343 .
If

, then angle

is obtuse and triangle with sides a, b, c is obtuse triangle.
In an arbitrary triangle can be only one obtuse angle, and the side which lies opposite to the largest angle is the largest. Then since <span>angle

is opposite the side of length a</span> you can conclude that a>c and a>b.
Answer:
93
Step-by-step explanation:
15 x 5 = 75 + 18 = 93
