4x-2y=8 ==> y=2x-4 (to better show you what I mean)
2 lines are parallel if they have the same slope (m the coefficient of x).
So y=mx + b // y =2x-4 means m=2 & y=mx + b, becomes y=2x + b.
Moreover they are telling us that this function passes by (-2,1), where -2 represents x & 1, represents y. To calculate b , replace x & y by their values:
y=2x+b ==> 1 = 2(- 2) + b==> 1 = -4 + b ==> b= 5. Finally the equation is
y=-2x+5
(1/2)(1/2)(1/2) = 1/8 or .125
That is your answer. Hope this helped.
Please mark me as brainliest.
Answer:
c
Step-by-step explanation:
work out the average for the data below
The range of a data set is the difference between the largest and the smallest value in the set.
Here the range is: r = 62 - 25 = 35
I'll assume those are squares. We know D is an identity:
Dividing through by
That's A.
Dividing the original through by
Not quite B, wrong sign on tangent.
C has the wrong sign on cosine squared as well.
Identities: A & D
