For the set of triangle vertices, find the coordinates of the vertices of the image after a dilation by the given scale factor. Then graph the preimage and image on a separate sheet of paper.
A (9, 9), B(3, 3), C(6, 0), k = 1/3

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b
