Answer:
2y = x+6
Step-by-step explanation:
From (y-1) = -2(x-1)
y-1 = -2x+2
y=-2x+2+1
y=-2x+3 compare with y = mx +C
m1= -2
For perpendicularity rule: m1m2 = -1
m2 = -1/-2 = 1/2
Equation of the line that passes through (0,3) is
y-y1 = m2(x-x2)
y-3 = 1/2(x-0) = 1/2(x)
y-3 = x/2
Multiply through by 2
2y-6 = x
2y = x+6
2y-x=6
2y-x-6=0

Answer:
Step-by-step explanation:
Lets assume the number of articles was x.
Half of the articles was bought at the price 1/5 rupee each and the other half was bought at the price 1/4 rupee each.
<u>Cost of articles:</u>
- 1/2x*1/5 + 1/2x*1/4 =
- 1/2x(1/5 + 1/4) =
- 1/2x(4/20 + 5/20) =
- 9/40x
<u>Money made after sale is:</u>
<u>The difference is 3 rupees:</u>
- 9/40x - 2/9x = 3
- 81/360x - 80/360x = 3
- 1/360x = 3
- x = 3*360
- x = 1080
Correct choice is B
Well if i had to make an educated guess my assumption would be similar to the hypothesis of this complicated situation now what i'm trying to say is i have no idea hope you find someone who can help you.
