Answer:
C. -12
Step-by-step explanation:
divide each side by 2/3
2/3x ÷ 2/3 = x
-8 ÷ 2/3 = -12
x = -12
 
        
             
        
        
        
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<span>
 </span>

Answer: 7
Step-by-step explanation:
Since we are given the information that a group of friends had 28 driveways to shovel and that one of them shoveled 1/4 of the driveways.
The number of driveways that he shovel will be:
= 1/4 × 28
= 7
Therefore, he shovel 7 driveways.
