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
D.) x = - 9
C.) x = 0
Hope that helps, Good luck! (:
The discriminant is

which is 0.
Since the discriminant is 0, there is only one real solution.
Answer:
40%
Step-by-step explanation:
38×100=3800÷95=40
40%×95=38
Correct answer is A. For example 50/2= 25 which is odd
