The rule to rotate the figure is (-y,x) making point A (4,0).
X = 3y - 6....so sub 3y - 6 in for x in the other equation
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24
solution is (24,10)
Simple....
you have:

You're trying to find b..so isolate it...

leaving you
a=c*b
still not done....


Thus, your answer.
Answer:
4 /25
Step-by-step explanation:
Given that :
Cup of vinegar used per recipe = 1/5 cup
Amount of vinegar to be used for 4/5 of a recipe ;
1 cup recipe = 1/5 cup vinegar
4/5 cup recipe = x
Cross multiply :
x = 1/5 * 4/5
x = 4/25 cup
Hence, Sandeep will use 4/25 cup of vinegar
