Step-by-step explanation:

-14x²-1≠0
x²≠ -1/14
Option C
105 is a composite number. 105 = 1 x 105, 3 x 35, 5 x 21, 7 x 15. Factors of 105: 1, 3, 5, 7, 15, 21, 35, 105. Prime factorization: 105 = 3 x 5 x 7.
7. increasing; non-linear
8.A. y=4^x
9.A. y=6x
Divide 100 to 56 = 56/100= 0.56 then you wanna times it by 50 so then it would be.56x50=28
