Answer:
Table C
Step-by-step explanation:
To find the constant of proportionality, you need to divide y by x
Table A has a constant of proportionality of <em>which is 0.3333 repeating</em>
Table B has a constant of proportionality of <em>which is 0.6</em>
Table C has a constant of proportionality of <em> which is 0.3</em>
Why? Because the denominators are both the same at 2x+8. We can only add or subtract fractions when the denominators are the same. The general rule for adding fractions is
We have numerators A and B added together over a common denominator C. If we didn't have a common denominator, then we'd have to do a bit of algebraic manipulation to get both fractions to a common denominator. It doesn't have to be the lowest common denominator (LCD), though it's often more efficient that way.
