For each equation determine whether it is linear.

A and B are linear because they follow the equation of a line formate: y=mx+b
Choice A doesn’t have a b component, but it is still linear. C and D aren’t linear because the x in choice C is squared and the x in choice D is x^3

Answer is A and B because that is the right answer and I got it right

31 is prime. and it’s prime factorization is just 31.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
