A polygon will be dilated on a coordinate grid to create a smaller polygon. The polygon is dilated usi X the origin as the center of dilation.
Which rule could represent this dilation?
A. (x, y) → (0.5 – x,0.5 - y)
B. (x, y) → (x - 7, y - 7)
C. (x, y) - (x, y)
D. (x, y) → (0.9x, 0.9y)

just put them in order

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
