Answer:
-3
Step-by-step explanation:
you can divide the second term by the first term to solve
39/-13 = -3
then, I like to check that this fits with the third term
39*-3 = -117
so the common ratio is -3
Answer:
The equation that represents the line passing through the point (2, -4) with a slope of one half is

Step-by-step explanation:
The equation of a line can be described by a first order equation in the following format:

In which a is the slope of the line.
Solution:
The line slope is
, so
.
The equation of the line now is:

The problem states that the line passes through the point(2,-4). This means that when x = 2, f(x) = -4
So:




So, the equation that represents the line passing through the point (2, -4) with a slope of one half is

Answer:
<em>Each side is 10 meters</em>
Step-by-step explanation:
Because since area is length times width, you would do 10x10 which is 100
The equation of line with undefined slope and x - intercept -7 is x = -7
<em><u>Solution:</u></em>
Given that the slope of line is undefined and the x intercept is -7
To find: Equation of line
If a line has undefined slope, then it is a vertical line
A vertical line has undefined slope because all points on the line have the same x-coordinate
<em><u>The equation of a vertical line always takes the form:</u></em>
x = b
where, "b" is the x - intercept
Given x - intercept is -7
<em><u>Thus the equation of line is:</u></em>

Therefore, the equation of line is found
Since it says the sum of any number not one in specific then the value will be x, plus the sum of 7,
