It’s b (OA= MA.) I took this quiz last week :)
The total number of common tangents that can be drawn to the circles is 1
<h3>What are the
tangent lines?</h3>
The tangent lines of a circle are the lines drawn, that touch the circle at only one point
<h3>How to determine the total number of
common tangents that can be drawn to the circles?</h3>
The complete question is added as an attachment
From the attached figure, we have the following highlights:
- The circles have different radii
- The smaller circle is completely inside the bigger circle
- Both circles have one point of intersection
The one point of intersection is the only point where both circles can have common tangents
Since there is only one point of intersection, then the number of common tangents on the circles is 1
Hence, the total number of common tangents that can be drawn to the circles is 1

Answer:
- parallel: y = x -1
- perpendicular: y = -x -3
Step-by-step explanation:
The given line has a rise of 1 for each run of 1, so a slope of 1. If you draw a line with a slope of 1 through the given point, you can see that it intersects the y-axis at y = -1. Then the slope-intercept equation is ...
y = x -1 . . . . . equation of parallel line
__
The perpendicular line will have a slope that is the opposite reciprocal of the slope of the given line: m = -1/1 = -1
A point that is 1 unit right and 1 unit down from the given point is -3 on the y-axis. This is the y-intercept of the perpendicular line. The equation is ...
y = -x -3 . . . . . equation of perpendicular line
-8x+3y=28
4x-y=-12
<u><em>Step-by-step explanation:</em></u>
Let's find x and y from matrices and then check for this systems.
Simplify, so we got
7-9
28-24
------
So x=-2
y=4
So we need to put those values and check system.
Given:
The arithmetic mean of three consecutive even integers is 20.
To find:
The equation that can be used to find the integers.
Solution:
Let the three consecutive even integers are x, x+2 and x+4.
We know that,
The arithmetic mean of three consecutive even integers is:
It is given that, mean = 20. So,
Therefore, the correct option is E.
