Answer:
Step-by-step explanation:
Domain of a function is a set of x-values (input values) for which the function is defined.
Range of a function is a set of y-values (output values) for the given set of input values.
7). Domain → (-∞, ∞)
     Range → (-∞, ∞)
8). Domain → (-∞, ∞)
     Range → [-2, ∞)
9). Domain → [-2, 2]
     Range → [-3, 3]
10). Domain → (-∞, ∞)
     Range → [-1, 1]
 
        
             
        
        
        
Answer:
2
Step-by-step explanation:
this is a 30-60-90 Δ and the ratio of the sides are 1 : 
 : 2
1 / 2 = 
 / x
cross-multiply: x = 2
 
        
             
        
        
        
Answer: True
Step-by-step explanation:
AB is congruent to RS
BC is congruent to ST
CD is congruent to TV
So DC would be congruent to VT
 
        
             
        
        
        
Answer:

Step-by-step explanation:
A quick review on PEMDAS, the order of how to solve an equation:
P - parentheses. When parentheses are being used, you have to do everything inside them before doing everything outside of them.
E - exponents. We'll skip these, since there aren't any exponents we need to worry about in this equation.
M/D - multiplication/division. I include these both together because they can be done at the same time.
A/S = addition/subtraction. Can also be done at the same time.
Some other things to note:
You add all the things with an x attached to it, and you add all the things without an x attached to it, and these never cross. 
When you bring something from one side of an equal sign to another, you make it negative.
Let's solve for x using what we've learned:
