The points (-7,-1) and (-8,6) fall on a particular line. What is its equation in point-slope form?

Arisa [49]

Answer:

y - 6 = -7(x + 8)

Step-by-step explanation:

Slope: m = (y2-y1)/(x2-x1) = (6 - -1)/(-8 - -7) = (6 + 1)/(-8 + 7) = 7/-1 = -7

Point-slope form: y - 6 = -7(x - -8)

=> y - 6 = -7(x + 8)

F(n)=3n-3 g(n)=n^2+4 find f(g(n))

Vera_Pavlovna [14]

Answer:

f(g(n)) = 3*n^2 + 9

Step-by-step explanation:

This is function composition.

f (g(n) ) = 3 *( n^2 + 4) - 3

simplify:

f (g(n) ) = 3 *n^2 + 12 - 3 = 3*n^2 + 9

Find the probability

4vir4ik [10]

Answer is in a box.

The bag contains 6 red marbles, 8 blue marbles and 9 green marbles, that is 23 marbles.

The probability that one of the 23 marbles will be picked is 1 or 100%, we are picking a marble for sure.

So what is the probability you will pick for example one of the 6 red marbles? It is 6 out of 23 but since we need percentages multiply by 100,

$\frac{6}{23}\cdot100\approx26.09\%$

The probability to pick a blue marble is,

$\boxed{\frac{8}{23}}\cdot100\approx34.78\%$

And the probability to pick a green marble is,

$\frac{9}{23}\cdot100\approx39.13\%$

To check that everything is right you can sum all the probabilities; the probability that it will be either red, blue or green is 100% so the individual probabilities must sum to 100%, and they do,

$26.09\%+34.78\%+39.13\%=100\%$

Hope this helps :)
