Answer:
see below
Step-by-step explanation:
See attached screenshot (too time consuming to type out using latex, so used MS word).
They charge $30 per month as a base so that is y
They also charge $0.25 per text message, this is x
so $0.25x+$30y=$59.50
first subtract 30 from both sides to get x alone
$0.25x=$29.50
To find amount of text messages sent, we have to divide
$29.50/$.25
29.50/.25=118
This person sent 118 text messages

Answer:
- R'(-2, 2)
- F'(2, 2)
- G'(-2, -2)
Step-by-step explanation:
It can be useful to keep a list of the 90° rotation transformations.
(x, y) ⇒ (-y, x) . . . . . . 90° CCW, 270° CW
(x, y) ⇒ (-x, -y) . . . . . . 180°
(x, y) ⇒ (y, -x) . . . . . . . 270° CCW, 90° CW
__
1) (x, y) ⇒ (-x, -y) . . . . 180°
R(2, -2) ⇒ R'(-2, 2)
__
2) (x, y) ⇒ (-y, x) . . . . 90°
F(2, -2) ⇒ F'( 2, 2)
__
3) (x, y) ⇒ (y, -x) . . . . 270°
G(2, -2) ⇒ G'(-2, -2)
