Answer: -6.7
Step-by-step explanation:
64.3−(3)(23)−2
=−6.7
Answer:
Dilation.
Step-by-step explanation:
From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .
Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.
But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.
Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".
Answer:

Step-by-step explanation:
Given Equation of line: y=mx+c,
where m = slope of line.
So, we will have to make y the subject to find the slope.

From here, we can see the slope of the line is
.
K is centroid of the the triangle => The answer is 7.5
