Step-by-step explanation:
Let 
be the coordinates of the point which has to be dilated with the scale factor of 
with the center of dilation at point 
(the origin).
The dilation with the scale factor and the center of dilation at the origin has the rule
So, you have simply to multiply each coordinate of the point by to get the image's coordinates.
Answer:
Step-by-step explanation:
Blank 1 = " x "
Blank 2 = " 3 "
The solution is x>18.
The problem tells us that 3 less than a number: x-3
is more than 15. >15
So the inequality is x-3>15. When we isolate x to simply the inequality, we add 3 to both sides, to get x>18.
