Answer:
x=5ft
Step-by-step explanation:
3 is half of 6, so triangle DEF is half as big as triangle ABC. Hope this helps.
 
        
             
        
        
        
Answer:
A.+4
Step-by-step explanation:
Graph pass (1 , 0) and (4 , 0)
y = (x - 1) (x - 4) = x² - 5x + 4
c = 4
 
        
             
        
        
        
The total cost would  be:
$20 = two people- 2*20=40$
20 = guest
20*20=
400 would be the cost
 
        
             
        
        
        
If a dime equals 10¢, and 10 dimes equals 100¢ (or $1) you need to divide.
$90.10/10¢=90.1 dimes you need I think.
Hope this helps
        
             
        
        
        
When dilation is about the origin, as it is here in every case, the image point coordinates are the original (pre-image) coordinates multiplied by the scale factor.
1. Multiply every coordinate value by 5:
... W' = (-5, 10), X' = (-15, -5), Y' = (25, -5), Z' = (15, 10)
2. Multiply every coordinate value by 1/3:
... A' = (-2, 5), B' = (0, 5/3), C' = (1, 10/3)
3. A' = (2, 8), B' = (6, 2), C' = (2, 2)
4. The image coordinates are 5 times the original coordinates, so ...
... the scale factor of the dilation is 5.
