Answer:
A lies along the positive x-axis and B lies along negative x - axis
.
Step-by-step explanation:
They tell us that we have two vectors, A and B. And they give us a series of conditions for this, now, what would be the correct possibility.
A lies along the positive x-axis and B lies along negative x - axis
.
This is because when both vectors will be in x axis but opposite to each other, then the angle between them will be 180 ° and cos180 ° is -1.
Answer:
8x2−8xy−6y2
Step-by-step explanation:
if your answer choices contain exponents then of course the number behind the x's are exponents.
-4, +1
And then the 20 letters i need to write are right here
3/4*1/4= 3/16 or 0.1875 (you times 3 by 1 and 4 by 4)
3/4*8= 6
first bracket = 3/16+ 6
1/2+2= 2 1/2 or 2.5
second bracket = -2.5
-3/8*4= -1.5
-3/8*x= -3/8x or -0.375x
third bracket= -0.375x
so
(0.1875+6) - (2.5) - (0.375x) - (0.25x)
collect like terms
6.2 - 2.5 = 3.7
0.375x - 0.25x = 0.125x
3.7-0.125x is your answer in decimal form
(3/16+6/1) - (2 1/2) - (3/8x-1/4x)
(6 3/16 - 2 1/2 )
(3 11/16)
3/8x-1/4x= 1/8x
final answer = 3 11/16 - 1/8x
