6x-2y=24
6(-5)-2(-3)=24
-30+6=24
-24=24
Yes
-10x-2y=-56
-10(-5)-2(-3)=-56
50+6=-56
56=-56
Yes
The answer is= Yes. The solution is (-5.-3)
By the way, you have to show the work.
Answer:
i think its 5, use the magic numbers of pythagoras theorem to help u it might not be correct, use at ur own risk
Supposing 2x-7 were a factor, then 7/2 would be a root. Use synth. div. to determine whether 7/2 actually is a root:
__________________________
7/2 / 6 -21 -4 24 -35
21 0 -14 35
----------------------------------------
6 0 -4 10 0
Since the remainder is zero, 7/2 is a root and 2x - 7 is a factor.
You could check out the other possible factors in the same manner.
If you plug in 1 for x, you get f(1) = 1^1, so it is just 1.
We need to see the graph. Ask Question again with graph attached.
