You can solve all of these by using the distance formula. I have shared it below.
Answer: (27, 9)
Multiply the original coordinates by the scale factor 3 to get this answer
9*3 = 27
3*3 = 9
This only works if the center of dilation is the origin.
The general rule is 
where k is the scale factor.
3/5 = 0.3 * x
3/5 is 30% of x - This is how they match up from the word problem to a number sentence
So to solve it...
3/5 = 0.3x
x = 3/5 ÷ 0.3 = 2
Answer:
-4x - 20x
Step-by-step explanation:
Multiply 2 by -10
The equation would be:
x - 9 < 4
Simplify (add 9)
Solution: x < 13
