Answer:</h3>
B. (0, 9)

Step-by-step explanation:</h3>
Reflection across x=a is represented by the transformation ...
... (x, y) ⇒(2a-x, y)
Reflection across y=b is represented by the transformation ...
... (x, y) ⇒ (x, 2b-y)
The double reflection, across x=2, y=1 will result in the transformation ...
... (x, y) ⇒ (2·2-x, y) ⇒ (4-x, 2·1-y) ⇒ (4-x, 2-y)
For (x, y) = X(4, -7), the transformed point is ...
... X''(4-4, 2-(-7)) = X''(0, 9)
By the chain rule,
so
You were able to find
, which requires knowing both
and
. Do you also happen to know

?
28°, 93° and 59°
let x be the first angle then the second angle = 3(x + 3)
and the third angle = 2x + 3
the sum of the angles in a triangle = 180° , thus
x +3x + 9 + 2x + 3 = 180
6x + 12 = 180 ( subtract 12 from both sides )
6x = 168 ( divide both sides by 6 )
x = 28
the angles are x = 28° , 3(x + 3 ) = 93° and 2x + 3 = 59°
In set theory, a set is a collection of objects (called members or elements) that is regarded as being a single object. ... For example, the set given by the rule “prime numbers less than 10” can also be given by {2, 3, 5, 7}.
