Answer:
the answer is 2: one pair of sides is parallel and the other pair is congruent.
Step-by-step explanation:
Given that △XYZ is mapped to △X'Y'Z' using the rules (x, y)→(x+5, y−3) followed by (x, y)→(−x, −y) .
We know that (x,y) => (x+h,y+k) type operation represents translation so rule (x, y)→(x+5, y−3) will cause translation.
We know that (x,y) => (-x,-y) type operation represents rotation about origin so rule (x, y)→(−x, −y) will cause rotation.
So combining both results and comparing with given choices. we find that only 1st choice "△XYZ is congruent to △X'Y'Z' because the rules represent a translation followed by a rotation, which is a sequence of rigid motions."
is correct.
Can you get a better picture of that?
Step-by-step explanation:
1/8 x 8 = 1
3/8 x 8 = 3
1/8 x 8 = 1
3/8 x 8 = 3
or x= twelve-fifths
Option A is correct.
Step-by-step explanation:
We need to find the solution of:
Solving:
Taking square on both sides:
Verifying the solution by putting x = 12/5 in the given equation, we get true result.
So, or x= twelve-fifths
Option A is correct.
