Answer: 0 = 3
Step-by-step explanation: If y = 7 - 3x, we can plug that in for y in the equation 3x + y = 10 by writing it as 3x + 7 - 3x = 10.
- 7 - 7
--------------------------
3x - 3x = 3
0 = 3
Answer:
A
Step-by-step explanation:
A
Answer:
standard form of the equation of a circle: (x - a)^2 + (y - b)^2 = r^2, where (a,b) is the center and r is the radius.
(x + 3)^2 + (y -10)^2 = 5^2
then just count
Answer:
<span>If two lines intersect, then their intersection is exactly one point
Explanation:
Let's take a look at the choices:
Choice A: </span><span>A line contains at least two points.
The statement is true. However, it is not related to intersection between lines. Therefore, this choice is wrong
Choice B: </span><span>Through any two different points, exactly one line exists
This postulate is true. However, it does not relate directly to the intersection between lines. Therefore, this choice is wrong
Choice C: </span><span>If two lines intersect, then their intersection is exactly one point.
This statement is known as theorem 1-1. It describes the intersection between two lines.
Therefore, this statement is correct.
Choice D: </span><span>If two lines intersect, then exactly one plane contains both lines.
The conclusion given is related to points created due to intersection between lines. This option is therefore excluded as it describes planes.
Hope this helps :)</span>
