Required
Find Y
To do this, we make use of the mid-point formula
i.e.

WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:


The mid-point of ZY is:

Equate both values of M

Multiply both sides by 2

By comparison:








Hence:

Answer:
Step-by-step explanation:
we have to find the dot product here.
From the formula of dot product of vectors,
we know-
if X=<a,b,c> and Y=<d,e,f>
Then dot product of X and Y is-
X.Y=ad+be+cf
Here, we get
v=<2 , -8 , -8>
and w=<-2 , 6 , -5>
So, the dot product is-
v . w=2(-2)+(-8)(6)+(-8)(-5)
=-4-48+40
=-52+40
=-12
So,
v . w= -12
The domain is going to be ur x values....the number of minutes
therefore, ur domain is : I know it is either A or C.....I am thinking C because it does not have to be a whole minute...it can be 1.5 minutes...so that would eliminate A. final answer is gonna be C
For the first one its (A) For the 2nd its (C) For the 3rd its (B)
because the y-intercept is 3, you'll place your first point up 3 on the y-axis (so (0, 3)). From there you can use your slope to graph the rest
Because your slope is -6, rise over run tells you it's pretty much -6/1, thus, from the point you placed on the y-axis you go down 3 places, and to the right 1. This makes your next point (-3, 1). For your last point you use your rise over run vice versa and go up 6 places, and to the left 1. This point would be (8, -1). If you connect these 3 points you'll have a pretty good graph
