If ratio of cost price to selling price is 5 :7 ,find the profit percentage, tell me​

let the cost price = 5x

let the selling price = 7x

profit = selling price - cost price

= 7x - 5x

= 2x

profit percentage = 2x/5x × 100

= 2×20

= 40 percent

idk im srry

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
