If XYZ is dilated by a scale factor of 3 about point Y, which of the following is true about A’ Y’? a) A’Y’ is perpendicular to AY
b) A’Y’ is parallel to AY
c) A’Y’ passes through the center of dilation
d) A’Y’ intersects with point X’

c) A’Y’ passes through the center of dilation

Step-by-step explanation:

Dilation is a type of transformation that can be used to resize the dimensions of a given figure. It does not affect the shape of the given figure, but retains its initial shape.

In the given question, dilating XYZ by a scale factor of 3 implies multiplying each side of the triangle XYZ by 3 about Y. This transformation would yield triangle X'Y'Z' and A'Y'.

Since the transformation is about point Y, A'Y' would pass through the center of dilation.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
