I think the correct answer would be A. The type of congruence transformation for the preimage ABC to EDC would be a reflection. It is a transformation where you basically flip the preimage or the original shape ove a line which is called the line of reflection. So, the image would be a mirror image of the preimage. By plotting the points, you will see that triangle EDC is just a mirror image of triangle ABC and the line of reflection would be at x = 3. It could not be a rotation since the preimage was not turned or rotated around a center of rotation. Also, it cannot be a translation since the preimage was not just moved left, right, up or down.
Get common denominators, and solve for each expression
7/5 - 3/4 = 28/20 - 15/20 = 13/20
1/4 + 2/5 = 5/20 + 8/20 = 13/20
These two fractions are equivalent
15.8% would round to 16%
If the number after the decimal point is 5 or greater you round the 5 up to a 6. If it had been less than a 5 it would have rounded down to 15%.
Answer:
Step-by-step explanation:
I believe if you multiply 850×2= 1700.
Multiply 850×3..
That would equal to 2550.
2a + 4 - 7a + a
2a -7a +a +4
-5a + a +4
-4a + 4
-4a + 4 is your answer
hope this helps
