Price of milk = p
p = 2.65 + y - 0.15 + 0.05
p = y + 2.55
9514 1404 393
Answer:
P = (8, 0)
Step-by-step explanation:
The coordinates of point P are the weighted average of the end points. The weights are the reverse of the segment divisions.
P = (2/5)A +(3/5)B
P = (2(-4, -6) +3(16, 4))/5 = (-8+48, -12 +12)/5 = (40, 0)/5
P = (8, 0)
Simultaneous Equations
3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
