Answer:
2x -3y = 21
Step-by-step explanation:
The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.
3x +2y = 6 . . . . . given equation
2x -3y = c . . . . . . coefficients swapped, one negated
2(6) -3(-3) = c = 21 . . . . . the value of c for the given point
The desired equation is ...
2x -3y = 21
160 = 100%
56 = x%
then you would cross multiply
160x = 56(100)
160x = 5600
x =
x = 35
so
35% of 160 is 56.
56 = x%
then you would cross multiply
160x = 56(100)
160x = 5600
x =
x = 35
so
35% of 160 is 56.
