Answer:

(6, 1)

Step-by-step explanation:

We are given the equation for (y), [y=x-5]

So we can implement that in all the places the (y) are in the other equation.

x+3(x-5)=9

x+3x-15=9

add 15 to each side

4x=24

Divide each side by 4

x=6

Now we can apply our (x) into one of the equations.

y=(6)-5

y=1

So our solution is (6, 1)

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Given the points A (-1,2) and B (7, 14), find the coordinates of the point P on directed line segment AB that partitions AB in t

Leya [2.2K]

Answer:

Now despite what you may believe, 1:3 is not 1/3 in this situation. In this case, it means "1 equal part to 3 equal parts", which is a total of 4 equal parts. In short, this question is to place point P 1/4 the distance from A to B.

Firstly, how far apart is -1 from 7 (the x-coordinates)? That would be 8 units. Multiply 1/4 by 8:

Next, how far apart is 2 from 8 (the y-coordinates)? That would be 6 units. Multiply 1/4 by 6:

Next, since from -1 to 7 you are increasing, add 2 to -1:

1 is your x-coordinate

Next, since from 2 to 8 you are increasing, add 3/2 to 2:

7/2 is your y-coordinate.

Putting it together, your answer is A. (1, 7/2)

Answer:

Probability of getting green, blue, red, and yellow = 0.69

Step-by-step explanation:

Given - A bag contains 7 marbles: one each of red, orange, yellow, green, blue, violet, and white. A child randomly pulls 4 marbles from the bag.

To find - What is the probability that the marbles chosen are green, blue, red, and yellow?

Proof -

Given that,

A bag contains 7 marbles: one each of red, orange, yellow, green, blue, violet, and white.

i.e.

All the outcomes are equally likely.

So,

The child can choose the 4 marbles in 4! ways.

And

Total number of ways = $^{7} C_{4}$ = 35

So,

Probability of getting green, blue, red, and yellow = $\frac{4!}{35}$

= $\frac{24}{35}$ = 0.69

⇒Probability of getting green, blue, red, and yellow = 0.69
