Answer:
x=9
Step-by-step explanation:
5( x + 7) - 3 ( x - 4) = 7x + 2
Distribute
5x+35 - 3x +12 = 7x +2
2x +47 = 7x+2
Subtract 2x from each side
2x+47-2x =7x -2x+2
47 = 5x+2
Subtract 2 from each side
47-2= 5x+2-2
45= 5x
Divide by 5
45/5 =5x/5
9 =x
 
        
                    
             
        
        
        
Answer:
c. y = -35*x + 105 
Step-by-step explanation:
Lo que demos hacer es calcular los puntos cuando x = 0 y cuando x = 3, es decir el inicio y el fin del recorrido.
Cuando x es igual 0, y = 105, por lo tanto, la función sería:
y = A*x + 105
Cuando x = 3, y = 0, por lo tanto:
0 =  3*A +  105
resolvemos para A:
3*A =  -105
A = -105/3 
A =  -35
Por lo tanto la función es:
y = -35*x + 105 
es decir, la opción c.
 
        
             
        
        
        
Answer:
FIRST OPTION
Step-by-step explanation:
its the first option since the birds like the red bugs more all the red bugs will get eaten and the green ones will survive and evolve
 
        
             
        
        
        
Answer:
Yes
Step-by-step explanation:
Graph this function on your calculator and you will see an upwards graph, if the range (y), -1 can be mapped on the graph, it is within the range.
 
        
             
        
        
        
Let's take a look at the first few numbers in the sequence based on the given rule:

Inspecting this pattern it seems like the power 

 is being raised to is always one less than the number of the sequence, so if we were on the nth number in the sequence, that part of the expression would be 

. We also know that we'll be multiplying whatever we get from that by 6, so we can write the full explicit rule for our sequence as

Where 

 is the nth number in our sequence.
