False, the estimated square root of 32 is 5.65685424... while 25/2 = 12.5
Ok, so if a zero is at r1, then a factor is (x-r1)
since there are no other roots, it must be only taht root
3rd degree so reaise it to the 3rd power
(x-r1)³
and the root is at x=-3
(x-(-3))³
(x+3)³
answer is f(x)=(x+3)³
also could be x³+27 where it factors to one real root and 2 complex roots
Imma take a guess maybe C
I believe the answer is B :-)
The equation you had:
6x + 5y = 45
Solve for Y:
5y = (-6x) + 45 divide by 5
y = (-6/5)x + 9
y = -1 1/5x +9
