Using the rule of radicals
×
⇔
Simplifying each radical before combining them.
=
= ×
= 3
-----------------------------------------------------------------------------
=
= ×
= 5
---------------------------------------------------------------------------
Hence
2(3) - 3(5
= 6 - 15
= - 9 → C
For a proportional relationship, the constant is found dividing all values of y by each respective value of x.
<h3>What is a proportional relationship?</h3>A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
The constant can be represented as follows:
Hence the constant is found dividing all values of y by each respective value of x.
