Answer:
Point X is the center of dilation.
Step-by-step explanation:
Consider the below figure attached with this question.
It is given that trapezoid TRAP was dilated by a scale factor of 1/2 to create trapezoid T'R'A'P'.
We need to find the center of dilation.
All points of the figure are expanded or contracted about a fixed point, that point is know as center of a dilation.
To find the center of a dilation, draw 4 lines which are connecting vertices with their corresponding images. The intersection point on these lines is the center of a dilation.
From the 2nd figure it is clear that lines TT', RR', AA' and PP' intersect each other at point X.
Therefore, point X is the center of dilation.
Answer:
-12
Step-by-step explanation:
4 1/2 - 5 1/8 = -0.625
7.5 x -0.625 = -12
The formula for slope is y1 - y2 all over x1 - x2
now that you know this, simply plug in the correct numbers for these variables
6 - 3 all over 0.4 - 0.2
you should get 3/0.2
i hope this helps !!
b= 14 because the formula to find a triangles area is 0.5bh. So, you take 147 and divide it by 21 then multiply the answer of that (which is 7) by 2 because the reciprocal of 0.5 is 2.
