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:
Amount of paint to be bought = 10 gallons
Step-by-step explanation:
Amount of paint needed by Mrs. Sullivan to paint her house = 12 gallons
She is already having paint = 8 quarts
Since, 1 quart = 0.25 gallons
Therefore, 8 quarts = 8 × 0.25
= 2 gallons
So, amount of paint she is already having = 2 gallons
Amount of paint to be bought = 12 - 2
= 10 gallons
Answer:
x = s, y = t, z = 8 -s -t
Step-by-step explanation:
It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.
You could get more elaborate if you want:
x = 4-s, y = 4-t, z = s+t
I dont know this one sorry
Tangent is Opposite over adjacent.
The opposite side of Angle A is 6 and the adjacent side is 8.
The tangent ratio would be 6/8
