Answer: y = -35x + 105
Step-by-step explanation:
The graph represents a function that is between hours and miles and to determine the equation which belong to this graph, we need to find the slope first by using two points from the graph which are (0, 105) and (3, 0).
The definition of slope is
m = (y2 - y1)/(x2 - x1)
= (0-105)/3-0
= -105/3
= -35
The slope is -35 and remember that the slope is the coefficient of the variable x. Therefore, the answer is:
y = -35x + 105
Answer:
40 points
Step-by-step explanation:
The score for the first four rounds of the game is 13, 17, 19, and 21 points.
Let 
and 
be the scores of the fifth and sixth games respectively in order to achieve an average score of 20 points per round for all six rounds.
Hence, the combined score of the fifth and sixth rounds are 40 points.
Area of circle = πd²/4, where d = diameter
= π*6*6/4 = 9π ≈ 9 *3.1416 ≈ 28.2744 cm²
Area ≈ 28.27 cm²
Hope this explains it.

Step-by-step explanation:
“The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.”
