Answer: The coordinates of triangle A'B'C',

A'≡(3/2, -9/4)

B'≡(-3, 9/4)

C'≡(3/2, 9/4)

Step-by-step explanation:

Since, the rule of transforming the triangle ABC by the scale factor -3/4,

(x,y)\rightarrow (\frac{-3}{4}x, \frac{-3}{4}y)

Thus, the coordinates of the transformed triangle A'B'C',

(-2, 3)\rightarrow (\frac{-3}{4}\times -2, \frac{-3}{4}\times 3)

(4, -3)\rightarrow (\frac{-3}{4}\times 4, \frac{-3}{4}\times -3)

(-2, -3) \rightarrow (\frac{-3}{4}\times -2, \frac{-3}{4}\times -3)

So, the coordinates are A'≡(3/2, -9/4)

B'≡(-3, 9/4)

C'≡(3/2, 9/4)

Answer:

1 and 7/12 hours

Step-by-step explanation:

2 and 1/3 is the whole. You need to subtract 3/4. To bring both of these to the same denominator, multiply each fraction by the others denominator. That means 1/3 is now 4/12 and 3/4 is now 9/12. They can now be subtracted. 2 and 4/12 - 9/12 = 1 and 7/12.
