Answer:
16
Step-by-step explanation:
x = number of footballs he can order
22*x + 13 (shipping fee) = 277
22x = 264 Subtract 13 from both sides
x = 16 Divide both sides by 22
Our solution is 16 footballs
The correct answer is <span>A) P'(3, −4), Q'(−3, 4), R'(6, −3)</span>
Rx = 0 indicates a reflection over the y-axis.
The rule for such a transformation is:
(x, y) --> (-x, y)
which means that the x-coordinate changes sign and the y-coordinate stays the same.
Therefore:
P<span>(-3, -4) --> P'(3, -4)
Q(3, 4) --> Q'(-3, 4)
R(-6, -3)</span> --> R'(6, -3)
These points are those in option A).
