The equation of a line is x + 4y = 15.
2 answers:
Answer:
Option D.
Step-by-step explanation:
Y-intercept form of the equation of a line is given by y = mx + c
Where m = slope of the line
c = y-intercept
Given equation of a line is x + 4y = 15
We will transform this equation into the y intercept form first.
x + 4y = 15
4y = 15 - x
y =
Therefore, y - intercept of this equation will be c =
Option D will be the answer.

First, we are going to find the radius of the yaw mark. To do that we are going to use the formula: 
where
is the length of the chord
is the middle ordinate
We know from our problem that the tires leave a yaw mark with a 52 foot chord and a middle ornate of 6 feet, so
and 
. Lets replace those values in our formula:
Next, to find the minimum speed, we are going to use the formula:
where
is <span>drag factor
</span>
is the radius
We know form our problem that the drag factor is 0.2, so
. We also know from our previous calculation that the radius is 
, so 
. Lets replace those values in our formula:
mph
We can conclude that Mrs. Beluga's minimum speed before she applied the brakes was 13.34 miles per hour.
