A line passes through (1, - 1) and (3, 5). What is the equation of the line in slope-intercept form?​
lisabon 2012 [21]

Answer: a+b+c=0 and 3a+5b+c=0

Step-by-step explanation:

If you find a solution to these equations, you will find an equation of your line. Please notice that (a,b,c) defines the same line as (ka,kb,kc) and for any non-zero k, and a=b=c=0 defines no line equation at all. Now you can take a=1 and solve for b and c, or take b=1 and solve for a and c, or take c=1 and solve for a and b, at least one of these will work.

Twenty-three student compete in a math competition in which the top three studentsare recognized with trophies for first, second
gladu [14]

Answer:

10626 ways

Step-by-step explanation:

Given

Number of students = 23

Prizes = 3

Required

Number of different outcomes for the top 3

This question will be solved using permutation formula because it implies selection of 3 students from 23

^nP_r = \frac{n!}{(n-r)!}

<em>Where n = 23 and r = 3</em>

The formula becomes

^{23}P_3 = \frac{23!}{(23-3)!}

^{23}P_3 = \frac{23!}{(20)!}

^{23}P_3 = \frac{23!}{20!}

^{23}P_3 = \frac{23 * 22 * 21 * 20!}{20!}

^{23}P_3 = 23 * 22 * 21

^{23}P_3 = 10626

<em>Hence, there are 10626 ways</em>
