What is the equation of the line that passes through the point (2,7) and has a slope
of 6?

Answers

Answer (assuming it can be in point-slope form):

[tex]y-7 = 6(x-2)[/tex]

Step-by-step explanation:

Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. All you need to do is substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.

Since [tex]m[/tex] represents the slope, substitute 6 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, take the x and y values of (2,7) and substitute them into the formula as well. So, substitute 2 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following equation and answer:

[tex]y-7 = 6(x-2)[/tex]

We will remove two marbles from a jar that contains 3 green marbles, 2 blue marbles, 1 white marble, and 1 black marble. We might consider the conditional probability that the second marble we remove is green given that the first marble removed was green. Use the multiplication rule to calculate P( second green | first green). Convert your answer to a decimal and round to three decimal places.

Answers

Answer:

P( second green | first green) = 1/3

Step-by-step explanation:

There are 7 marbles in the jar in total

After the first pick, given the marble removes is green marbles, how many green marbles are there left in the jar? How many marbles are there left in the jar?

Green marbles left: 2

Marbles left: 6

Using the multiplication law of probability,

P(A∩B) = P(A) x P(B|A)

P(second green | first green) = P(second green and first green) / P(first green)

P(second green and first green) = 3/7 x 2/6 = 1/7

P(first green) = 3/7

∴(1/7) / (3/7) = 1/3

Thus, we come up to the conclusion P( second green | first green) = 1/3

When asking for f(-5) or any other number, they are asking you to plug in that number for x.

So, f(-5) = 6(-5) - 3
