Before dilation:
the height of the triangle is h₁ = 7 - (-1) = 8
the width of the triangle is w₁ = 7 - (-5) = 12

After dilation:
the height of the is h₂ = 9-7 = 2
the width of the triangle is w₂ = -5 - (-8) = 3

The scale factor is h₂/h₁ = 2/8 = 1/4 = 0.25
Also, the scale factor is w₂/w₁ = 3/12 = 1/4 = 0.25

Answer: The scale factor is 0.25

What are the coordinates of the point? A coordinate grid with a dot placed in the second quadrant. The dot is to the left of pos

GenaCL600 [577]

We know that the point is in Q II. Thus, the x-coordinate of this point will be negative and the y-coordinate will be positive.

The y-coordinate is essentially given, and is y=4.
Imagine drawing a vertical line thru x=-2. This line will intersect y=4 at (-2,4).

The coordinates of the point are (-2, -4).

Are these numbers divisible by 2,3,5,10 444: 90: 45:

anyanavicka [17]

444 ÷ 2 = 222

444 ÷ 3 = 148

90 ÷ 2 = 45

90 ÷ 3 = 30

90 ÷ 5 = 18

90 ÷ 10 = 9

45 ÷ 3 = 15

45 ÷ 5 = 9

So 444 can be divided into 2 and 3

90 can be divided into 2, 3, 5, and 10

45 can be divided into 3 and 5

Hope this helps. :)
