Explain how the multiplication property for inequalities differs from that of equations

1 answer:

4 0

It doesnt differ lets take 10 = 6 + 4 multiply thru by a negative and flip the sign -10 = -6 - 4 flipping an equals sign about seems redundant, but the process works nonetheless <span>having two separate rules for solving inequalities and equalities seems pointless

RS is perpendicular to MN and PQ.

We can use the slopes of these lines to determine the answer.
Slope is given by the formula
m=.

Using the coordinates for M and N, we have:
m=.

Since PQ is parallel to MN, its slope will be as well, since parallel lines have the same slope.

Using the coordinates for points T and V in the slope formula, we have
m=.

This is not parallel to MN or PQ, since the slopes are not the same.
We can also say that it is not perpendicular to these lines; perpendicular lines have slopes that are negative reciprocals (they are opposite signs and are flipped). This is not true of TV either.

Using the coordinates for R and S in the slope formula, we have
m=. Comparing this to the slope of RS, it is flipped and the sign is opposite; they are negative reciprocals, so they are perpendicular.
