y = 2x + 3 - it's a linear function. We only need two points to plot the graph. Select two any x values and calculate the y values:
for x = 0 → y = 2(0) + 3 = 0 + 3 = 3 → (0, 3)
for x = -2 → y = 2(-2) + 3 = -4 + 3 = -1 → (-2, -1)
y > 2x + 3
Dot line an shading above the line (look at the picture).
Answer:
About 384.3 feet
Step-by-step explanation:
The formula for that is given by,
Where,
S is the speed of the car
d is the distance of skid
f is the drag factor for the road surface
n is breaking efficiency as percentage
Putting the values we get,
feet
So the length of skid marks would be 384.3 feet.
