A line contains (9,y) and (-6,3). It has slope 2/3, find y
koban [17]

The line contains (9,y) and (-6,3) Then y is 13

<em><u>Solution:</u></em>

Given that a line contains (9, y) and (-6, 3)

Slope of line is \frac{2}{3}

To find: y

<em><u>The slope of line is given as:</u></em>

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

\text {Here }\left(x_{1}, y_{1}\right)=(9, y) \text { and }\left(x_{2}, y_{2}\right)=(-6,3)

<em><u>Substituting the values in formula,</u></em>

m=\frac{3-y}{-6-9}

Substitute m = \frac{2}{3}

\frac{2}{3}=\frac{3-y}{-6-9}

2(-6 - 9) = 3(3 - y)

Multiplying the terms with terms inside bracket

-12 - 18 = 9 - 3y

Move the variable to one side

-30 = 9 - 3y

On solving we get,

3y = 30 + 9

3y = 39

Divide both sides by 3, we get

y = 13

Thus y = 13

Ken is going to throw a biased dice once.
satela [25.4K]

Answer:

0.7

Step-by-step explanation:

Given a biased dice :

Probability of landing on 6 = P(6) ;

P(6) = 0.3

Recall :

P(A') = 1 - P(A)

Therefore,

If

P(6) = 0.3

P(not landing on 6) ; P(not 6) ;

P(not 6) = 1 - P(6)

P(not 6) = 1 - 0.3 = 0.7

Hence, Probability of not landing on 6 = 0.7

What is X-24 = 58; x= 82
Alecsey [184]
But that doesn't really make sense, because if x has already been solved, then the equation makes sense, because if we substitute x into it, then we have 82-24, which is 58. I could be wrong... sooo... but I hope it helps?

When m and I are cut by transversal n. if m&lt;3=67° , determine m&lt;6.​
marshall27 [118]

Answer:

  • 113°

Step-by-step explanation:

Angles 3 and 6 are consecutive interior angles

<u>As per definition, consecutive internal angles add to 180°</u>

  • m∠3 = 67° ⇒
  • m∠6 = 180° - 67° = 113°
