4x+8y=40
0.8*8=6.4
4x+6.4=40
40-6.4=33.6
4x=33.6
33.6\4=8.4
X=8.4
        
             
        
        
        
Answer:
ANSWER
y = 3x + 6.50
EXPLANATION
The $3 for each downloaded movie is the unit rate of change.
This is represent the slope of the linear function that models this situation.
The monthly fee of monthly fee of $6.50 the constant rate.
It represents the y-intercept of the function.
The linear function is given by
y = mx + by=mx+b
The correct choice is y = 3x + 6.50
 
        
                    
             
        
        
        
20 is the answer.
15% of 50= 7.5
45% of 50= 22.5
22.5+7.5=30
50-30=20.
        
             
        
        
        
Answer:
No solution
Step-by-step explanation:
4x + y = -2
-20x - 5y = -3
<u><em>Using the Elimination method </em></u>
(4x + y = -2 ) 5
20x + 5y = -10
-20x - 5y = -10
0 = -10
No Solution
 
        
             
        
        
        
The limit of the expression as x approaches -3 is -24
<h3>How to determine the limit of the expression?</h3>
The expression is given as:

As x approaches -3.
The limit expression becomes

Substitute -3 for x in the expression

Evaluate the expression
