Mrs Lopez types at a constant rate. The constant of proportionality for the relationship between the number of words she types, w, and the number of minutes she types, m, is 38.Write an equation to show this relationship.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

Let

w ----> the number of words she types

m ---> the number of minutes she types

we have

In this problem the constant of proportionality k is equal to

substitute

x=6 and x=3

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
