Mathematics

Dominik [7]3 years ago

Answer:

Step-by-step explanation:

Step 1: Sum of angles on a straight line is 180

Step 2:

2x + 25 + y = 180

2x + y = 180 - 25

2x + y = 155  (1)

Step 3:

3x - 10 + y = 180

3x + y = 180 + 10

3x + y = 190    (2)

Step 4: Substract equation 1 from 2

3x + y - 2x - y = 190 - 155

      x = 35

Step 5:

Substitute x in equation 1 to find y

2x + y = 55

2(35) + y = 155

70  +  y = 155

  y = 155 - 70

   y = 85

Graph the function f(x) = x3 – 3x – 2. Based on the graph, which value for x is a double root of this function? a.–2 b.–1 c.1 d.
dalvyx [7]
To solve the problem shown above you must apply the following proccedure:

 1. You have the following function given in the problem:

 <span> f(x)=x3–3x–2

 2. When you give values to the x and plot each point obtained, you obtain the graph shown in the figure attached.

 3. Based on the graph and analizing the alternate form:

 f(x)=(x-2)(x+1)</span>²

 As you can see, there is two roots x=-1, then, you can conclude that the correct answer is the option b, which is:

 b) -1
