Answer:
The slope of a horizontal line is zero
Step-by-step explanation:
All horizontal lines are parallel to the x-axis.
The x-axis has a zero slope.
All parallel lines have the same slope.
Therefore the slope of a horizontal line is zero.
This means there is no rise in y.
So rise over run will become:
0/run=0

Answer:
Step-by-step explanation:
Given that:

if we assume that x is zero, then
,
i.e the radius of the circle goes from -6 to +6, Similarly, if we assume that z is zero, then
,
,
. This implies that
describes the circle with radius 6
is an equation at region which consist of those points whose distance from the centre is at least with radius -6 and at most 6.
Therefore, the region is the solid cylinder of radius 6, where the Y axis is also the axis of the cylinder.
Step-by-step explanation:
The longest side of a triangle must be less than the sum of the shorter sides.
If 8 and 12 are the shorter sides, and c is the longest side, then:
c < 8 + 12
c < 20
If c and 8 are the shorter sides, and 12 is the longest side then:
12 < c + 8
4 < c
The range of possible lengths for the third side is:
4 < c < 20
