Answer:
Part 1) The ordered pair is (0,0)
Part 2) The ordered pair is (-2,-4)
Part 3) The ordered pair is (4,8)
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
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have a direct variation
Complete the ordered pairs
Part 1) we have (0,?)
For x=0
Substitute in the equation and solve for y
therefore
The ordered pair is (0,0)
Part 2) we have (-2,?)
For x=-2
Substitute in the equation and solve for y
therefore
The ordered pair is (-2,-4)
Part 3) we have (4,?)
For x=4
Substitute in the equation and solve for y
therefore
The ordered pair is (4,8)
Answer:
s = 10
Step-by-step explanation:
Given s is inversely proportional to t , then the equation relating them is
s = ← k is the constant of proportion
To find k use the condition when s = 0.6, t = 5
0.6 = ( multiply both sides by 5 )
3 = k
s = ← equation of proportion
When t = 0.3, then
s = = 10
