Answer:
x = -9
Step-by-step explanation:
- 2(x + 7) = 4
Distribute
-2x -14 = 4
Add 14 to each side
-2x-14+14 = 4+14
-2x = 18
Divide each side by -2
-2x/-2 = 18/-2
x = -9
 
        
             
        
        
        
Step by step explanation 
area= 2πrh
-> 2 * 3.14 * 2 * 9
-> 6.28 *18
-> 113.04
        
             
        
        
        
We are given the functions:
f(x) = 4 x – 5                       --->
1
g(x) = 3 x + 7                       --->
2
 
To find for the value of f(x) + g(x), all we have to do is
to add equations 1 and 2:
f(x) + g(x) = 4 x – 5 + 3 x + 7
f(x) + g(x) = 7 x + 2 = y
 
In this case, for any real number value assign to x, we get
a real number value of y. This is because the function is linear.
Therefore the domain of the function is all real numbers.
 
        
             
        
        
        
Answer:
y este egal cu 1
x este egal cu un
Step-by-step explanation:
2 plus 2 egal cu patru( adica 2 ori unu plus 2 ori 1)
La fel si la cea cu 3.
