Step-by-step explanation:
Given function is y = –x.
Substitute the values of x in the function and find the values of y.
y = –x
At x = –2,
y = –(–2) = 2
At x = –1,
y = –(–1) = 1
At x = 0,
y = –(0) = 0
At x = 1,
y = –1(1) = –1
At x = 2,
y = –(2) = –2
Now, substitute the values of y in the table.
The image of the table is attached below.
Answer:
Kevin's constant of proportionality,k = $8.25 per hour
Greg's constant of proportionality,k = $9 per hour
Savannah's constant of proportionality,k = $9.5 per hour
Step-by-step explanation:
1. What is the constant of proportionality, k, of Kevin's wage? Greg's? Savannah's?
Solution
y = kx is a proportional variation
Where,
y and x are represent two different variables
k represent constant of proportionality
From the attached table,
Let
y = wages earned (in dollars)
x = hours worked
To find the constant of proportionality k of Kevin's wage, divide the variable y (total earned) by the variable x (number of hours)
Using any points on the table
Take (8,66.00) for example
constant of proportionality k of Kevin's wage = variable y (total earned) / variable x (number of hours)
= 66.00/8
= 8.25
k = $8.25 per hour
B. Constant of proportionality of Greg's wage = variable y (total earned) / variable x (number of hours)
Using (9, 81.00)
k = 81.00/9
= 9
Greg's k = $9 per hour
C. Constant if proportionality of Savannah's wage = variable y (total earned) / variable x (number of hours)
Using (6, 57.00)
k = 57.00/6
= 9.5
Savannah's k = $9.5 per hour
Therefore,
Kevin's constant of proportionality,k = $8.25 per hour
Greg's constant of proportionality,k = $9 per hour
Savannah's constant of proportionality,k = $9.5 per hour
