Help!!! I need to find the x and y values
gayaneshka [121]

The solution is that x = 26 and y = 9.

In order to find these, we need to note that since the two angles involving x's make a straight line, then they must equal 180 degrees. So we can add them together and set them equal to solve for x.

5x - 17 + 3x - 11 = 180 ----> combine like terms

8x - 28 = 180 ----> add 28 to both sides

8x = 208 -----> divide by 8

x = 26

Now that we have the value of x, we can find the value of the 3x - 11 term. That along with the right angle and the 2y + 5 angle combine to make another straight line. So we can solve by setting that equal to 180 as well.

3x - 11 + 90 + 2y + 5 = 180 ------> Combine like terms

3x + 2y + 84 = 180 -----> Put 26 in for x.

3(26) + 2y + 84 = 180 -----> Multiply

78 + 2y + 84 = 180 ------> Combine like terms again

2y + 162 = 180 ------> Subtract 162 from both sides

2y = 18 -----> Divide by 2

y = 9

Archie is stranded in a war zone in the land of the Xhosas. His only chance of survival is to reach Sudland, which lies 100 mile
LenaWriter [7]

Answer:

The  chances of success for Archie is P(S|D) =  35\%

Step-by-step explanation:

From the question we are told that

 The distance of Sudland from Xhosas is   d =  100 miles

  The probability  of failure is  P(F) = 0.26

  The probability of choosing the desert route is   P(D) = \frac{1}{40} =  0.025

The probability of reaching Sudland through the mountain is  P(S|M) =0.75

Generally the probability of choosing the  mountains route is

         P(M) = 1 - P(D)

           P(M) = 1 - 0.025

             P(M) = 0.975

Generally the probability of success is mathematically represented as

       P(S) =  1- P(F)

         P(S) =  1- 0.26

          P(S) =  0.74

       

Generally the probability of success in reaching Sudland is also mathematically represented as

     P(S) =  P(S|M) * P(M) + P(S|D) * P(D)

=>   P(S|D) =  \frac{P(S) - P(S|M) * P(M)}{P(D)}

substituting values

=>  P(S|D) =  \frac{0.74 - 0.75 * 0.975}{0.025}  

=>  P(S|D) = 0.35  

=>  P(S|D) =  35\%

The graph of which function has a y-intercept of 3?
masya89 [10]

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

In this problem we have a function with a y-intercept of 3

That means

The point (0,3) belongs to the graphic of the function

therefore

the answer in the attached figure

Pleaseeeeee help me find the answer
Thepotemich [5.8K]

Answer:

1/2

Step-by-step explanation:

Let's pick two points and find the slope inbetween them.

I'll pick (2,1) and (0,0).

Remember that slope = change in y / change in x.

slope = 1-0 / 2-0 = 1/2
