I will make x as small as possible, so x=0, y=25. 6 * 0 + 3 * 25=75.
the answer is 75
24, it has divisers 1, 2, 3, 4, 6, 8, 12, 24
Ahh...Owinner. the sign is greater and EQUAL to, so -5 and -1/2 are actually valid solutions there.
the answer is
(−∞,−5]∪(−1,−12]
I'm not sure if you can use 1 in the first blank but here's what I got
3x2+12x−4−2x2+6x+7=x2+18x+3=(x+9)2−78=1(x+9)2+(−78)
