Answer:
<u>Option 3:  0 ≤ x ≤ ∞ </u>
Step-by-step explanation:
The domain of a function is the set of all possible x values for the function.
The given function is y = √x
The domain for the square root function should be : x ≥ 0 
So, the domain = [0,∞)
Or, it can be written as inequality 
So, 0 ≤ x ≤ ∞ 
So, the answer is option 3.
 
        
             
        
        
        
Answer:
68
Step-by-step explanation:
The expression is given as: 
4( 3+ 7y) + 6(2 - y)
It is known that y is equal to 2. Therefore, substitute 2 in for y. 
4(3+7(2))+6(2-2) 
Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction 
Solve inside of the parentheses first. 
4(3+7(2))+6(2-2) 
4(3+14)+6(0)
4(17)+6(0) 
Multiply 
68+0 
Add 
68
 
        
             
        
        
        
Answer:
x = 16
Step-by-step explanation
Find the diagram attached. You can see from the diagram that both angles are vertically opposite angles and vertically opposite angles are equal.
Hence 2x+13 = 3x-3
Collect like terms
2x-3x = -3-13
-x = -16
Multiply both sides by -1
-1(-x) = -1(-16)
x = 16
Hence the value of x is 16
