Answer:
the answer is i dont know
Answer:
- x = 8
- AM = 64 cm
- BM = 64 cm
- M is the midpoint
Step-by-step explanation:
<u>Part A</u>. The total length of a line segment is the sum of the lengths of its parts.
AM +MB = AB
Substituting the given information, this equation becomes ...
(7x +8) cm + (9x -8) cm = 128 cm
16x = 128 . . . . . . . . . collect terms, divide by cm
x = 128/16 . . . . . divide by the coefficient of x
x = 8
__
<u>Part B</u>. Then the length of AM is ...
AM = (7x +8) cm = (7(8) +8) cm = (56 +8) cm
AM = 64 cm
__
<u>Part C</u>. The length of BM is ...
BM = (9x -8) cm = (9(8) -8) cm = (72 -8) cm
BM = 64 cm
__
<u>Part D</u>. AM = BM = 64 cm, so point M is the midpoint of AB. Point M divides the segment into two equal parts.
Answer:
C. A'(3,4), B'(-1,3), C'(-1,-1)
Step by step answer:
The coordinates of the vertices are A(-3,-4), B (1,-3), C(1,1).
We have the formula for the rotating a shape at an angle of 180° which shows that you are reflecting the shape twice.
(x, y) -> (-x, -y)
So, the coordinates will be,
A(-3,-4) = A'(3,4)
B (1,-3) = B'(-1,3)
C(1,1) = C'(-1,-1)
