Answer:
C
Step-by-step explanation:
∠1 = 3x + 18            {Vertically opposite angles}
∠1  + 28° = 90
3x + 18 + 28 = 90
3x + 46 = 90
3x = 90 - 46
3x = 44
x = 44/3

 
        
             
        
        
        
Answer:
44fps, or 44:1
Step-by-step explanation:
it is already a unit rate
 
        
                    
             
        
        
        
If your question is how many positions are possible, then the answer is 24.
We find this by thinking of how many people can be in each spot. If there are 4 spots each person can stand (back left, back right, front left, front right), then there are 4 possible choice for the first spot (mom, dad, son, daughter), then 3 for the next spot (since 1 is already in a spot), then 2 options for the next spot, and then 1 option for the last spot. In other words, the answer is 4x3x2x1, or 4 factorial.
        
             
        
        
        
The answer is B) 20
Because you have 5 brands and you combine each with the 4 others, so 5*4=20
 
        
                    
             
        
        
        
Answer:
1. No vertical compression or stretching but will open up downward.
2. 1/4 vertical stretch
3. 4 vertical compression
Step-by-step explanation:
Any time your dealing with vertical stretching or compression it will always be the number before the parentheses. 
So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression
2. Is the 1/4 is a vertical stretch 
3. 4 is a vertical compression. 
Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be.
