The minimum number of times two planes can intersect is zero, because if the planes are parallel to each other, they will never intersect. we can take the example of floor and roof, both are parallel to each other and no intersection. If the two planes are in same plane the maximum number of times they can intersect is infinite for example if we consider a line we can intersect at infinite points.
Answer:
30
Step-by-step explanation:
Given: There are six finalists and two medals. That is it asks for the possibilities of 6 finalists taking two at a time. Say, for example the first and third finalist or the second and the sixth finalist and so on. The number of possibilities is given by 
So the number of possibilities of 6 finalists taken two at a time is 
![$ \implies \frac{6!}{(6 - 2)!} = \frac{6!}{4!} \hspace{15mm} [n! = n \times (n-1) \times (n - 2) \times . . . 2 \times 1] $](https://tex.z-dn.net/?f=%24%20%5Cimplies%20%5Cfrac%7B6%21%7D%7B%286%20-%202%29%21%7D%20%3D%20%5Cfrac%7B6%21%7D%7B4%21%7D%20%20%5Chspace%7B15mm%7D%20%5Bn%21%20%3D%20n%20%5Ctimes%20%28n-1%29%20%5Ctimes%20%28n%20-%202%29%20%5Ctimes%20.%20.%20.%202%20%5Ctimes%201%5D%20%24)
Answer:
y=-1/2+3
Step-by-step explanation:
first, we have to determine if the slope is positive or negative. if it is going up to the right, it is positive. if it goes up to the left, it is negative. to find the slope, we need two or three points where the x and y values are both whole numbers. for this, we can use the y-intercept (0,3), (-2,4), and (-4,5). we can look at the line and see that from (0,3) to (-2,4) the line rises 1 and runs -2. this supports the claim that the slope is negative. from (-2,4) to (-4,5), the line rises 1 and runs -2. this is the same as the slope from (0,3) to (-2,4), so we can say that it is the slope of the line. since slope is written as rise over run, we can write the slope as -1/2. for the y-intercept, or b, we have to see what y is when x is 0. y is 3, so the y intercept is 3. in y=mx+b, m=slope and b=y intercept, so we plug these values in and we have the graph in slope intercept form.
Answer:
B. 
Step-by-step explanation:
We have been given a system of equations. We are asked to choose the ordered par that is the solution to the given system.
To solve our given system, we will equate both equations as:
Combine like terms:
Upon substituting 
in equation (1), we will get:
Therefore, the ordered pair is the solution of the given system and option B is the correct choice.
