Answer:
-2
Step-by-step explanation:
slope = y2 - y1 / x2 - x1
= 9 - (-3) / -2 -4
= 12 / -6
= -2
Answer:
Step-by-step explanation:
y = kx
If y = 25x , then k = 25
Answer:

Step-by-step explanation:
A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:

Solving, we will get a in terms of b:

Now we can substitute a for (b+3) into our equation:

Therefore, the length of each side of this polygon is
.
Since the perimeter of the polygon consists of all five sides, the perimeter is:

Answer:
Given equation of the line,

If x = 0,

Thus, the line intercepts y-axis at (0,-2)
If y = 0,

Thus, the line intercepts x-axis at (3.5,0)
By joining these two points in the graph,
We will get the graph of the given line ( shown below )
Answer:
Geometric Mean = 9.17
Step-by-step explanation:
Here,
a = 7
b = 12
Geometric mean = root(ab)
= root( 7 x 12)
= root(84)
= 9.17
