What is the constant of variation? Write your answer as a fraction.
In the given context the constant of variation(k) is 2/5.
What is the constant variation?The link between variables remains constant because of the constant of variation.
It is useful to use one of the following formulas to determine the constant of variation for an equation/
If k is the variational constant, then either x = k/y (inverse variation) or
x = ky (direct variation) should be used.
From the given graph we can observe the relationship between the number of postcards Kendra buys is related to the number of days is in direct variation when x = 5, y = 2.
∴ x = ky.
5 = 2k.
k = 2/5.
The constant of variation is 2/5.

A triangle has side lengths of ( 4h + 2k) centimeters, (9h + 4m) centimeters, and (2m - k) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
P = (13h+k+6m) cm
Step-by-step explanation:
Given that,
The side lengths of a triangle are :
(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm
We need to find the perimeter of the triangle.
We know that,
Perimeter = sum of all sides
So,
P = (4h + 2k)+(9h + 4m)+(2m - k)
= (4h+9h)+(2k-k)+(4m+2m)
= 13h+k+6m
Hence, the perimeter of the triangle is (13h+k+6m) cm.
