Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:
Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.
Answer:
4 hours

3+1=4
Answer:
The solution for the equation is
.
Step-by-step explanation:
-Solve the equation:

-Subtract 7x from 2x:

-Divide both sides by -5:


So, the answer is
.
Answer:
13th square number+4th cube number=233
Step-by-step explanation:
=233
Answer:
So the end points of the mid segment are:
S
T
Step-by-step explanation:
First of all we need to list the co-ordinates of the points of the triangle shown.
P
Q
R
We need to find mid segment of the triangle which is parallel to segment PQ. This would mean we need to find midpoints of segment PR and QR and then join the points to get mid segment.
Midpoint Formula:

Midpoint of PR:
S(
S
Midpoint of QR:
T
T
So the end points of the mid segment are:
S
T
By mid segment theorem we know that the line joining midpoints of two sides of a triangle is parallel to the 3rd side.
∴ We know ST is parallel to PQ
