Answer:
C
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
A(3, 4 ) → A'(- 3, 4 )
Since the point A and it's reflection lie on a horizontal line then
distance between = | 3 + 3 | = | 6 | = 6
Answer:
2. y, because ΔABC = ΔEDC
Step-by-step explanation:
- Both sides, angles are similar.
- B and D has an angle of 65 degree
- E and A has angle of y
That's why B is best option.
Answer:
- B. Ry-axis(x, y) → (–x, y)
Step-by-step explanation:
<u>As per the graph we see that:</u>
- Reflection over y-axis, y- coordinates remain as is, x- coordinates change to opposite
<u>So the rule is:</u>
- Ry-axis (x, y) → ( - x, y)
Correct option is B
Answer:
2.4 years
equal height is 72 inches
Step-by-step explanation:
initial height of tree one = 36inches
initial height of tree two = 48inches
36 + 15x = 48 + 10x
15x = 12 + 10x
5x = 12
x = 2.4 years
