Solution: The dilation of gk by a scale factor of 2 centered at (-2,-4) is 
and 
.
Explanation:
It is given that the scale factor is 2 and center of dilation is (-2,-4).
If the center of dilation is (a,b) with scale factor k, then the dilation of a point P(x,y) is determined by the given formula.
.....(1)
To find the g' substitute x=0, y=0, a=-2, b=-4 and k=2 in equation (1).
To find the k' substitute x=4, y=4, a=-2, b=-4 and k=2 in equation (1).
Therefore, the dilation of gk by a scale factor of 2 centered at (-2,-4) is and .
27) Since it doesn't say which unit you're going to use, I'll say 3.5 inches.
28) 5.6 Ounces?
29) 375,000 Litres.
30) 120 Yards.
31) 355 ML.
32) 1,117KM.
I hope this much helped, the other questions my brain was too fried to do them, let me know if you need help with any of those though!
Well, we kinda hope that noone is splitting the students into parts;) so that means that the number of students must be divisible by 4 and 9, and since they don't have any divisors in common, it must be divisible by 4*9=36, and this is also the correct answer - 36.
