Answer:−x2−6xy+8y2+9yz−12
The coordinates for the dilation of a triangle is (3 12), (12.15), and (6.0).
- If the coordinate (x, y) is dilated by a scale factor of k, the resulting coordinate will be at (kx, ky)
- Given the coordinate of the triangle (1 4). (4.5), and (2.0), if this coordinate is dilated by a factor of 3, the resulting coordinates will be at (3 12), (12.15), and (6.0).
Hence the coordinates for the dilation of a triangle is (3 12), (12.15), and (6.0).

i would start by simplifying the equation to get y by itself, you don't need to do this, but it makes it a little easier
y + 2 = 3 ( x + 4) distribute the 3 through the parenthesis
y + 2 = 3x + 12. subtract 2 from both sides
y = 3x +10
now to fill in the chart simply plug in the value of x to see what value of y it produces
y = 3(-2) +10
y = -6+10
y = 4
(-2,4)
y = 3(0) + 10
y = 0 + 10
y = 10
(0,10)
y = 3(2)+10
y = 6 + 10
y = 16
(2,16)
y = 3(4) + 10
y = 12 + 10
y = 22
(4,22)
What percent of 25 is 5?
5/25
5 ÷ 25 = 0.2
0.2 × 100 = 20
20%
5 is 20% of 20.
The correct answer to that question is T = 12
