I think the answer to your question is 11.11 I hope this helps
<span>(5x^7 y^2)(-4x^4 y^5) =-20x^a y^b
</span><span>
solve this:
(5x^7 y^2)(-4x^4 y^5)
= -20 x^(7 + 4) y^(2 + 5)
= -20 x^11 y^7
answer
</span>A) a=11, b=7
Ok ok I know you hate links but this is the only way to show you the answer.

Answer:
The corresponding point is (-4.-1)
Step-by-step explanation:
we know that
The point (-4,2) is on the graph of f(x)
so
For x=-4
f(x)=2
therefore
For x=-4
-(1/2)f(x)=-(1/2)*2=-1
The corresponding point is (-4.-1)
Check the forward differences of the sequence.
If 
, then let 
be the sequence of first-order differences of 
. That is, for n ≥ 1,
so that 
.
Let 
be the sequence of differences of ,
and we see that this is a constant sequence, 
. In other words, is an arithmetic sequence with common difference between terms of 2. That is,
and we can solve for 
in terms of 
:
and so on down to
We solve for 
in the same way.
Then
and so on down to
