Answer:

-5

Step-by-step explanation:

(4 \:  \:  ,\:  \:  \:  - 1) =  > (x1 \:,  \:  \: y1) \\ (2 \:  \:   \:  \:  \:  \: , \:  \:  \:  \: \: 9) =  > (x2 \:  \: , \:  \: y2)

slope \\  =  \frac{y1 - y2}{x1 - x2}  \\  =  \frac{( - 1 - 9)}{(4 - 2)}  \\  =  \frac{ - 10}{2}  \\  = -5

hope this helps

brainliest appreciated

good luck! have a nice day!

Answer:

-5

Step-by-step explanation:

The slope is given by

m= (y2-y1)/(x2-x1)

   = (9 - -1)/ ((2 - 4)

   = (9+1)/(2-4)

   = 10/-2

   = -5

1.2) Q5.) The graph is a transformation of one of the basic functions. Find the equation that defines the function.
Yuri [45]
The graph starts at around x = 0. At x = 0, the graph's y-value is 2. There are no x-values that are less than 0.

The graph crosses the following points: (1,1); (4,0); (9, -1)

 The distance between each y-value is exponentially increasing, as the slope of the graph is slowly decreasing as x approaches infinity.

Based on this information, we can say that this graph is a transformation of the base function, y = √x

To determine the transformations made, we need to compare the graph to the original base function (attached below).

The basic function starts at 0, and has a positive slope. It reaches the points (1,1); (4,2); and (9,3). 

The graph in the question shows the function start at 2, and the negative slope reaching the points mentioned earlier in the answer. 

Based on this information, we can conclude that y = -√x + 2.

Please help I dont understand​
Kitty [74]

Answer:

3rd option

Step-by-step explanation:

A direct variation is expressed in this form:

y = kx

1. y - 4x = 8

y = 4x + 8 is not a direct variation

2. y + 2 = 7x

y = 7x - 2 is not a direct variation

3. y - 3x = 0

y = 3x is a direct variation

4. y = 5x - 2

y = 5x - 2 is not direct variation

Jonathan is rolling to dice and needs to roll and 11 to win the game he is playing what is the probability that Jonathan wins th
hjlf

Answer:

1 / 18

Step-by-step explanation:

In a roll of two dice :

Number of faces on a dice = 6

Total sample space for 2 6-sided dice = (number of faces)^Number of dice = 6^2 = 36

Total possible outcomes = 36

Required outcome = sum of 11

11 = {(5,6) ; (6, 5)}) = 2 possibilities

Probability = required outcome / Total possible outcomes

P(obtaining a sum of 11) = 2 / 36 = 1/18
