Answer:

$1467

Step-by-step explanation:

We must convert the first 3 values to yards as so: 5 ft, 4 ft, and 8 inches. We then convert 8 inches to 2/3 feet. multiply 5*4*2/3 to get 13 and 1/3. multiply that by 110, to get 1466 and 2/3. Round it to $1467

Describe the transformation.
Anna007 [38]
Hi there! The answer is C.

We can see a reflection across the x-axis. The x-axis in this figure is an axis of symmetry. When we would measure the distance from a certain point in both of the triangles (the same point in the two triangles), this distance would be the same. Therefore this figure is reflected across the x-axis.

3 + 4×2 - 10 = 0

3 + 8 - 10 = 0

11 - 10 ≠ 0 (false)

b)

- 3 + 4×3 - 10 = 0

12 - 3 - 10 = 0
