1. Which one of the following sequences of transformations shows that circle X is similar to circle Y?
a. A translation of circle X 6 units to the right, 6 units down,
and a dilation with a scale factor of 2
b. A translation of circle X 6 units to the right, 6 units down,
and a dilation with a scale factor of
c. A translation of circle X 6 units to the left, 6 units up, and
a dilation with a scale factor of 2
d. A translation of circle X 6 units to the left, 6 units up, and
a dilation with a scale factor of 1/2

see explanation

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 -

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
