Answer:
y=9
Step-by-step explanation:
Answer:
a. rotation; then reflection across x
Step-by-step explanation:
The transformation shown is a reflection across the y-axis.
The first part of each answer choice is a rotation 180°. That rotation is fully equivalent to reflection across both the x- and y-axes, in either order. In order to have a net effect of reflection across the y-axis, the reflection across the x-axis must be cancelled--by another reflection across the x-axis.
The reflection across y shown is equivalent to ...
rotation 180° followed by reflection across the x-axis.
The triple card can be any one of 13 values (ace through king). For each of those, the double card can be any one of the remaining 12 values. So concerning only the face values of the cards, there are (13 x 12) = 156 different full hice. If you include attention to the suits, then there a lot more.
That's accurate, but what help do you need?
