Answer:
Step-by-step explanation:
-2(v-2)=-3-2v
Opening bracket
-2v + 4 = -3 - 2v
Collecting like terms
-2v + 2v = -3 - 4
No solution because v is eliminated
Answer:
$690.86
Step-by-step explanation:
100% from the original cost is: 2 x 863.57 = $1,727.14
40/100 = X/1727.14 (40 percent is what of 1,727.40) (%/100 = is/of)
(40 * 1,727.14) / 100 = $ 690.86
Hey there, I think this might help you.
Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y =
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y =
From the given equation; slope is
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line =
Since y= 9 and x = -7;
So;
9 = + C
9 = + C
C = 9 - =
Now,
y = x +
mulitply through by 5;
5y = -2x + 31
Answer:
Not necessarily
Step-by-step explanation:
Lets take v1 = (1,0,0), v2 = (1,1,0) and v3 = (0,1,0). Neither of the vectors are a multiple of the other, however they dont generate R³ because for example the vector (0,0,1) is not a linear combination of v1, v2 and v3.
Not that, despite not being a multiple of v1 or v3, v2 is a linear combination of v1 and v3, because it is the sum of both of them. Therefore, the three vectors are linearly dependent and they cant generate a 3 dimensional vector subspace.
