Answer:
You would end up with X= -2, y= 2
And they would intersect at point (-2,2) on a graph :)
 
        
                    
             
        
        
        
Answer:
113
Step-by-step explanation:
we need to know how much Lou has first !
so we have to do 682 / 6 which = 113
then 113 / 4 = 28.2
28.2 is how much Lou has
so we will go back and multiply the 4
28.2 x 4 =113 
 
        
                    
             
        
        
        
Answer:
81.85%
Step-by-step explanation:
Given : 
The average summer temperature in Anchorage is 69°F. 
The daily temperature is normally distributed with a standard deviation of 7°F .
To Find:What percentage of the time would the temperature be between 55°F and 76°F?
Solution:
Mean = 
Standard deviation = 
Formula : 
Now At x = 55


At x = 76


Now to find P(55<z<76)
P(2<z<-1)=P(z<2)-P(z>-1)
Using z table :
P(2<z<-1)=P(z<2)-P(z>-1)=0.9772-0.1587=0.8185
Now percentage of the time would the temperature be between 55°F and 76°F = 
Hence If the daily temperature is normally distributed with a standard deviation of 7°F, 81.85% of the time would the temperature be between 55°F and 76°F.
 
        
             
        
        
        
3-(2x-5)=-4(x+2)
We simplify the equation to the form, which is simple to understand 
3-(2x-5)=-4(x+2)
Remove unnecessary parentheses
3-2x+5=-4*(x+2)
Reorder the terms in parentheses
3-2x+5=+(-4x-8)
Remove unnecessary parentheses
+3-2x+5=-4x-8
We move all terms containing x to the left and all other terms to the right. 
-2x+4x=-8-3-5
We simplify left and right side of the equation. 
+2x=-16
We divide both sides of the equation by 2 to get x. 
x=-8
