Answer:
92°
Step-by-step explanation:
By exterior angle theorem:

 
        
             
        
        
        
<span>Here let the quadratic equation be ax^2 + bx + c
We know that a=5 from the question.
Since the roots are 6 and 2, the quadratic equation would take the form of a product like (a1x-b1)(a2x-b2).
However, let's assume that a2=1 and b2=6,
Since a=5, a1=5, then 5x-b1=5(x-2). Solving this shows that b1=10
So, the equation is (5x-10)(x-6)</span>
        
             
        
        
        
Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years. 
First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it. 
141 + 161 = 302 
Now, that we know how much Jack saves per month. 
Then, we have to find out how many months are in 2 years. 
We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2. 
12 x 2 = 24 
Therefore, there are 24 months in two years. 
Lastly, multiply 24 months by the amount that Jack saves to get the amount in total. 
24 x 302 = 7,248 
Thus, Jack will save approximately $7,248 in 2 years.
 
        
                    
             
        
        
        
Step one rewrite: -46-8x>22
Add 46 to both sides: -8x>68
Divide both sides by -8 to isolate x<-8.5
(remember to flip the inequality sign when multiplying or dividing by negative numbers in inequality problems)
So the correct answer is B. x < -8.5
