Answer:
What is the average time it took the car to travel 0.25 meters?
2.23 seconds
What is the average time it took the car to travel 0.50 meters?
3.13 seconds
Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.
Step-by-step explanation:
y-7=4(x-2)
we need to simplify the y to het a
y-7=4x-8 (i did 4x-8 because of 4(x-2)
now y= 4x-8+(-7)
after calculating -8+(-7) IT becomes
y=4x-15
okay we have the guide Line
y=4x-15
the a is 4
because
a = {y=a.x+b}
now we need to find the points using this guide Line
y=4x-15
x= 2(you can add any number here ,we Just need to know where the point is )
y= 4(2)-15
y=8-15
y= -7
points are (2,7)
Step-by-step explanation:
Where are all the sets?
Y=mx+b
trial and error tells us
f(x)=-0.25x+10 (the given equation doesn't give the correct starting value)
rate of change is -0.25
