Answer:
The rule or formula for the transformation of reflection across the line l with equation y = -x will be:
P(x, y) ⇒ P'(-y, -x)
Step-by-step explanation:
Considering the point

If we reflect a point
across the line
with equation
, the coordinates of the point P flips their places and the sign of the coordinates reverses.
Thus, the rule or formula for the transformation of reflection across the line l with equation y = -x will be:
P(x, y) ⇒ P'(-y, -x)
For example, if we reflect a point, let suppose A(1, 3), across the line
with equation
, the coordinates of point A flips their places and the sign of the coordinates reverses.
Hence,
A(1, 3) ⇒ A'(-3, -1)
You do 27 divided by 90 27/90=0.3 and then move the decimal two places which would give you 30%
Answer: Isolate the variable by dividing each side by factors that don't contain the variable. x=−1/2^2
Step-by-step explanation:
The pattern is that every 2 numbers are a pair, the first being any selected number, and the second number next to is the number times 3.
3 x 3 = 9
4 x 3 =12
7 x 3 = 21
Therefor we type 16 x 3 = 48
48 is your next number.
