The image of the dilation is shown below, with the centre of dilation (0,0) and scale factor of 3
The coordinate of C' is (6, -3) which is three times of the coordinate of C(2, -1)
B is correct.
A. 5(x-2)= 5x-10
B. 4(x+3)= 4x + 12
C. 3(x+1)= 3x+3
D. 2(x+7) = 2x + 14
There are two plausible answers
1. <span><span>x = -3/5 = -0.600
</span><span>2.x = 7/2 = 3.500</span></span>
The image of x is the point (7,5).
Draw the line x= 3 and treat it like a mirror.
When you reflect the points of the triangle just count how many units each point is from the mirror (x=3)
Count the same number of points in the opposite direction (away from the mirror) and you will arrive at the coordinates for the points
