Step-by-step explanation:
the vertices of S under the translation ![\left[\begin{array}{ccc}0\\-3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%5C%5C-3%5C%5C%5Cend%7Barray%7D%5Cright%5D)
are
(2, 3 ) → (2, 0 )
(6, 3 ) → (6, 0 )
(4, 5 ) → (4, 2 )
Under an anticlockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) then the above coordinates become
(2, 0 ) → (0, 2 )
(6, 0 ) → (0, 6 )
(4, 2 ) → (- 2, 4 )
which are the coordinates of the vertices of the image T
then the rotation is 90° anticlockwise about the origin , point (0, 0 )

Step-by-step explanation:
Answer:
<em>6). 7 years , 29 members ; 7). $5 is the price of the child movie ticket, $15 is the price of the adult movie ticket. </em>
Step-by-step explanation:
<em>6).</em> y = 50 - 3x
y = 15 + 2x
15 + 2x = 50 - 3x
5x = 35
x = <em>7 years</em>
y = 15 +2(7)
y = <em>29 members</em>
In 7 years game club and sport club will have 29 members.
<em>7).</em> 2a + 3c = 45 ......... (1)
2a + 2c = 40 ......... (2)
(1) - (2)
c = <em>$5 is the price of the child movie ticket</em>
2a + 2(5) = 40
a = <em>$15 is the price of the adult movie ticket</em>
