Which rule deacribes the
Marysya12 [62]

Answer:

A. {T_{-6,-2}}\circ {r_{x-axis}}(x,y)

Step-by-step explanation:

We have that, ΔABC is transformed to get ΔA''B''C''.

We see that the following transformations are applied:

1. Reflection across x-axis i.e. flipped across x-axis.

Now, ΔABC is reflected across x-axis along the line AC to get ΔA'B'C'.

2. Translated 2 units down i.e. shifted 2 units down and and then translated 6 units to the left i.e. shifted 6 units to the left.

So, ΔA'B'C' is translated 2 units downwards and 6 units to the left to get ΔA''B''C''.

Hence, the sequence of transformations is Reflection across x-axis and then Translation of 2 units down and 6 units left.

Evaluate twenty-five minus three x for x equals zero, one, two, three, and four. Which of the following correctly describes the
laiz [17]

Answer:

You take turns plugging in each number for your answers. I’ll list them below.

6(0) - (0)2 = 0

6(1) - (1)2 = 4

6(2) - (2)2 = 8

6(3) - (3)2 = 12

6(4) - (4)2 = 16

6(5) - (5)2 = 20

6(6) - (6)2 = 24

The pattern I’ve noticed is every time you increase the value from the previous meaning for x, the solution increases by 4. I hope this helps and let me know if I’m right.

Natali5045456 [20]

Answer:

8.05 miles

Step-by-step explanation:

If it descended 2.2 miles to 5.85 miles then that means it was at 5.85 + 2.2 miles before its descent.

5.85 + 2.2 = 8.05
