Answer:
y = -1 + 1
Step-by-step explanation:
The line (a) passing through point (3, -4) is perpendicular to line (b) whose equation is; y = -2 + x
The slope of line (b) =
For perpendicular lines, the product of their slopes = -1
So line (a) has a slope of: -1 ÷ = -
Taking another point (x,y) on line (a);
Slope = change in y ÷ change in x
= -
y + 4 = (x - 3)
y = -x + 5 - 4
y = -x + 1
Finally,
y = -1 + 1
Answer:
The correct option is 2.
Step-by-step explanation:
According to the the center-of-gravity technique, the coordinates of the center-of-gravity location are
Where ( represent the coordinates and
is demand.
We have to find the Y-coordinate of the center-of-gravity location.
The sum of product of demand and corresponding y coordinates is
The sum of demanded units is
The Y-coordinate of the center-of-gravity location is
The Y-coordinate of the center-of-gravity location is 131. Therefore the correct option is 2.
Here, we know that,
