Step-by-step explanation:
Since it's a direct variation
y = kx
where k is the constant of proportionality
To find the value of y when x = –0.5 we must first find the relationship between the variables
When
x = 3
y = 2
2 = 3k
Divide both sides by 3
So the formula for the variation is
<h3>
</h3>
When x = - 0.5 or - 1/2
We have the final answer as
<h2>
</h2>
Hope this helps you
A correlation coefficient of 1 or -1 indicates that the variables form a perfect linear relationship.
You need to swap the x values around. They need to be given in the same order as the y values. The sum should be:
Answer:
Segment DE is half the length of segment AC. -- Substitution property of equality
Step-by-step explanation:
Here is given a proof for proving line joining mid segment is parallel and half the length of third side.
Stepwise proof is given in two columns
We find that for every line there is a justification as
STatement Justification
D and E coordinates found out MId point formula
DE and BC are measured Distance formula
DE=1/2 BC Substitution property of equality
This justification was missing in the given proof and with this included proof would be complete
