Answer:
6(2 - 5k^4).
Step-by-step explanation:
12k^0 - 30k^4
Now k^0 = 1 so the polynomial becomes
12 - 30k^4
= 6(2 - 5k^4).
Nobody wants to do these because, I don't know why.

Answer:
(-1,-7)
Step-by-step explanation:
Substitute 2x-5 (from the first equation) as the y-value for the second equation, so you have something that looks like this:
2x-5 = -2x-9
Add 2x to both sides: 4x-5 = -9
Add 5 to both sides 4x = -4
Divide both sides by 4: x = -1
Substitute -1 for x in either equation (you'll get the same y-value)
