Determine if there's direct variation between x and y
The general form of direct variation is:

Make y the subject of formula in the given parameters;

<em>Since they are not of the same form, then the given equation do not show direct variation</em>
Answer:
5/8 is smaller.
Step-by-step explanation:
A ratio is just a different type of fraction, a 5:8 ratio means 5/8 which is 0.625. A 7:9 ratio equals 7/9 which is 0.777777
Then to compare them you see which is smaller or bigger.
0.77777 is bigger than 0.625 so we know that 0.77777777 which was the 7:9 ratio is the bigger one.
Is the equation suppose to be f(x)=x^2 and g(x)= x+5^2-9? the triangle thing means to the power of
