The negative sign means that this is reflected about the y-axis (this is not in the choices so we can ignore this).
The factor of 0.4 means it is compressed (since the factor is < 1).
Since the term inside the radical is x - 2, this means that we translate the graph 2 units to the right.
So the only correct descriptions are: compressed by a factor of 0.4, and translated 2 units to the right.
I got this:
5²+5=30
For the work, I just took the square I though was closest to 30, and added 5.
Hope this helps!
-17(y - 2) = -17y + 64
Distribute the -17
-17y + 34 = -17y + 64
Add 17y to both sides
34 = 64
Once the variables cancel, and you end up with a FALSE statement, this means there are NO SOLUTIONS.
