She did not multiply both sides of the equation by 2.
2x-6y =-2
<u>+ 2x+6y=3
</u><u /> 4x =1
x=1/4
y=5/12
I believe your answer is D, because vertical angles are congruent
Thee function is given as:
<span>v(t)=t^2−2tv(t)=t^2−2t
</span>(a) What is the initial velocity?
Base from the function, the initial velocity would be zero.
(b) When does the object have a velocity of zero?
It would be during time zero. Also, at a time equal to two.
Answer:
yes
Step-by-step explanation:
A line is a one-dimensional figure having no thickness and extends infinitely in both directions.
Direction ratios of the line joining points
are given by
.
Direction ratio is a number proportional to the direction cosine.
Direction ratios of a line joining points (−4, −6, 1) and (−2, 0, −3):

Direction ratios of a line joining points (12, 20, 7) and (7, 5, 17):
Ratios of the direction ratios:

We know that two lines are proportional if their direction ratios are proportional.
So, the given lines are parallel.
