Kaitlyn solved the equation for x using the following calculations. -5.4 +x =12.2 -5.4 -5.4= x=6.8: A:She should have added 5.4 to each side B:She should have added the inverse of 5.4 to each side C: She made a computational error when she subtracted 5.4 from 12.2 D:She should have added 12.2 to each side.

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

How can you tell when x and y are not directly proportional?
