Answer:
(x, y) ---> (-x, y).
Step-by-step explanation:
When we reflect across the y-axis the y coordinate remains unchanged but the x coordinate changes sign:
(x, y) ---> (-x, y).
It would be 80 fives & 44 tens.
80 fives is $400 and 44 tens is $440.
Answer:
can be factored out as: 
Step-by-step explanation:
Recall the formula for the perfect square of a binomial :

Now, let's try to identify the values of
and
in the given trinomial.
Notice that the first term and the last term are perfect squares:

so, we can investigate what the middle term would be considering our
, and
:

Therefore, the calculated middle term agrees with the given middle term, so we can conclude that this trinomial is the perfect square of the binomial:
