x = 185

Step-by-step explanation:

Given:

Plan A

Fixed cost = $14.80

variable cost = 10 cents per min = $0.1 per minute

Plan B

Fixed cost = $18.50

variable cost = 8 cents per min = $0.08 per minute

Computation:

Assume

Plan A cost = Plan B cost

14.80 + 0.1x = 18.50 + 0.08x

x = 185

yes

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
