Answer:

47. 1 5/8

48. 1 1/12

Step-by-step explanation:

47.

First, convert the denominators to be the same.

8 1/2 minutes, Ruby's mile time, can be converted to 8 4/8.

Then subtract.

8 4/8 - 6 7/8 = 1 5/8

48.

Make sure the denominators are the same. Both denominators can be multiplied by 3 or 4 to become 12.

1 1/4 can be multiplied by 3 to get 1 3/12. And 1 1/3 can be multiplied by 4 to get 2 4/12.

Then subtract.

2 4/12 - 1 1/3 = 1 1/12

Graph the image of △UVW after a reflection over the line y=-x

aliya0001 [1]

Answer:

9514 1404 393

see attached

Step-by-step explanation:

Reflection over the line x = -1 alters the x-coordinates, but leaves the y-coordinates alone. The image point is as far horizontally from the reflection line as the pre-image point is. Each new x-coordinate is the old one subtracted from twice the x-value of the line of reflection: (x, y) ⇒ (-2-x, y) U(-8, -6) ⇒ U'(6, -6) V(-3, -6) ⇒ V'(1, -6) W(-4, -1) ⇒ W'(2, -1)
