Answer:
Step-by-step explanation:
You simply need to substitute the numbers in the x column into the equations in the topmost row. The answers are the values of a, b, c, d, e, and f.
Look at the filled in cells.
In the x column, we have -2, and the topmost row we have 
. The answer is given as 
. This is because 
Repeat this for the values that you need to find.
Answer:
im going with number 3 sorry if im wrong
Step-by-step explanation:
Answer:
choose B. 54 meters/second, it is closest to my calculation of 55 meters/sec
Step-by-step explanation:
To find average speed between 3 and 8 seconds, find the total distance traveled during that time.
650 meters at 3 seconds
to 375 meters at 8 seconds
then average speed = ( 650 - 375 ) / (8 - 3) = 275 /5 = 55 meters /sec
Yes, a linear relationship (mathematical) is a constant change happening to x, for example, if in the first step it adds 2 to the table chart or graph, it will always be adding 2 every step of the equason
Using quadratic formula you can have a maximum of two solutions. When you set this problem equal to zero, your a=-1, b=-10, c=2
