what is the equation of the following line ? be sure to scroll down first to see all answer options (0,0) (-2,-3)
jenyasd209 [6]

to get the slope of any line, all we need is two points off of it, so let's get the slope and thus its equation, hmmmm  let's see points (-2,-3) and the origin are the obvious ones =)

\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{0}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{0-(-3)}{0-(-2)}\implies \cfrac{0+3}{0+2}\implies \cfrac{3}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-3)=\cfrac{3}{2}[x-(-2)]\implies y+3=\cfrac{3}{2}(x+2) \\\\\\ y+3=\cfrac{3}{2}x+3\implies y=\cfrac{3}{2}x

In how many ways can the letters of the word POLICEMAN be arranged if the 'word' must begin with L and end with a vowel? &amp; W
Vladimir79 [104]

Answer:

20160 ways

Probability = 0.0556

Step-by-step explanation:

We have 9 different letters, so the total number of words we can make is:

Total = 9! = 362880\ words

If we want just the words that begin with L and end with a vowel, we would have the first letter "locked", so we have 8 letters remaining, and it must end with a vowel, so the last "slot" has just 4 possible values (A, E, I or O). Then we would have 4 possible values for the last letter and 7 remaining letters in the middle of the word:

N = 4 * 7! = 4*7*6*5*4*3*2 = 20160\ words

The probability is calculated by the division of the number of words we want over the total number of words:

P = N / Total = 20160 / 362880 = 0.0556

How many positive integers less than 2018 are divisible by at least 3, 11, or 61?
Schach [20]
To find all the positive integers less than 2018 that are divisible by 3, 11, and 61, you will use what you know about factors.

3, 11, and 61 are all answers.  So are 33, 183, 671, and 2013.

If you put these in factors, the product will be divisible by them!

3 x 11 = 33
3 x 61 = 183
11 x 61 = 671
3 x 11 x 61 = 2013

Take each number and square it, cube it, etc...
9, 27, 81, 243, 729
121, 1331

9 x 11 = 99
27 x 11 = 297
81 x 11 = 891

121 x 9 =1089
121 x 3 =  363

61 x 9 = 549
61 x 27 = 1647

Everything in bold is a correct answer.
