Indicate in standard form the equation of the line passing through the given points G (4,6) H (1,5)
Delicious77 [7]

First, find the slope (m) = \frac{y2 - y1}{x2 - x1} = \frac{5 - 6}{1 - 4} = \frac{-1}{-3} = \frac{1}{3}

Now plug in ONE of the points and the slope into the point-slope equation:

y - y₁ = m(x - x₁); where (x₁, y₁) is the chosen point.

y - 5 = \frac{1}{3}(x - 1) (I used (1,5) as the chosen point)

3(y - 5) = x - 1

3y - 15 = x - 1

3y -14 = x

-14 = x - 3y → x - 3y = -14

Answer: x - 3y = -14

Four possibilities have probabilities 0.4, 0.2, 0.2 and 0.2 and values $40, $30, $20, and $10 respectively. The expected value i
LiRa [457]

Answer:

b. ​$28

Step-by-step explanation:

We have these following probabilities:

0.4 = 40% probability of $40

0.2 = 20% probability of $30

0.2 = 20% probability of $20

0.2 = 20% probability of $10

The expected value is:

We multiply each value by its probability. So

E = 0.4*40 + 0.2*30 + 0.2*20 + 0.2*10 = 28

So the correct answer is:

b. ​$28

Is y=x+9 linear or is it not linear
avanturin [10]

Answer: It is linear. When a line is linear it just means it makes a straight line when you graph it. When it isn’t it will be curved or in some weird shape.

The sum of two numbers is 50 and the difference is 12. What are the numbers?
Strike441 [17]

Answer:

The two numbers are 31 and 19

Step-by-step explanation:

Let x and y be the numbers

x+y = 50

x-y = 12

Add the two equations together

x+y = 50

x-y = 12

-----------------

2x +0y = 62

Divide by 2

2x/2 = 62/2

x = 31

Now find y

31+y = 50

Subtract 31

y = 50-31

y = 19

Enter the values needed to find the length CB
Tju [1.3M]

Answer:

6b

Step-by-step explanation:

We know that the distance formula is \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}. We already have the x values, which are 5a and -a, subtracting -a from 5a gets us 6a.

Same concept for the y values, let's subtract the first y value from the second.

The second y value is b, while the first is -5b

b - (-5b) = b + 5b = 6b

Hope this helped!
