Find the ratio of 3 km to 3000 m

Let f(x) = 5/x and g(x)=2x2+5x. what two numbers are not in the domain of f o g

Hich equation can pair with x + 2y = 5 to create an inconsistent system? 2x + 4y = 3 5x + 2y = 3 6x + 12y = 30 3x + 4y = 8

Select all expressions that are equivalent to 2(3x + 7y). question 1 options: 6x + 14y 6x + 7y 1(6x + 14y)
