The angle of impact is 30°
<h3>What is the angle of impact?</h3>
In a bloodstain, the angle of impact can be used to determine the appearance of the resulting bloodstain if the bloodstain has a tail or pattern.
- Bloodstain pattern analysis is the study of bloodstains at a scene of the crime in an attempt to reconstruct the events that resulted in the bloodshed.

Remember that parallel lines have the same slope.
y=3/7x+11 (in slope intercept form already)
-3x+7y=13 (standard form)
Add 3x to both sides, giving you 7y=3x+13, divide by 7 on both sides, giving
y=3/7x+13/7
Since both equations' slopes' are the same, their graphs will be parallel.
Answer:
c = 15 meters
Step-by-step explanation:
This is solveable using the Pythagorean Theorem,
let's say a = 9 and b = 12,
a^2 + b^2 = c^2, so
9^2 + 12^2 = 225 then,
sqrt(225) = 15, so c = 15 m
Answer:
x =2
Step-by-step explanation:
y = - 2 x + 4
0 = - 2 x + 4
x = 2
The points of intersection are (-2, -2) and (5, 5), so clearly y = x. This reduces the choices to the first and third ones.
Since x-4 is the denominator of all choices, its value at the point (5, 5) will be 1. Hence you need to find the choice that has a numerator of 5 when x=5.
The first choice has a numerator of -5-10 = -15, so that's not it.
The third choice has a numerator of -5+10 = 5, so that's the one you're looking for.
The best choice is the third one, ...
... y = negative x plus ten divided by the quantity x minus four , y = x
