Answer:

Step-by-step explanation:
- For a horizontal compression, we multiply whole numbers greater than 1 in front of  of the given function. of the given function.
- For horizontal expansion, we multiply by the reciprocal of the number for horizontal compression, in front of  of the function. of the function.
For example, 
If we wanted to <u>horizontally compress</u>  , we would multiply by 4 to get
, we would multiply by 4 to get  , and
, and
if we wante to <u>horizontally expand</u>  , we would multiply by
, we would multiply by  to get
 to get 
Since this question asks for horizontal compression, we multiply the  of the function by 4. So the function we need is
 of the function by 4. So the function we need is  . The second choice is correct.
. The second choice is correct.
 
        
             
        
        
        
Answer:
y = x + 1
Step-by-step explanation:
This is in slope intercept form. 1 is the point that you start at: (0, 1)
The slope is 1
y = 1x + 1 or
y = x + 1
 
        
             
        
        
        
Answer:
tan(9pi/12) = 0.041146549
Step-by-step explanation:
 
        
             
        
        
        
It’s a kite because angle B is equal to angle D (both 105) and it all adds up to 360 making it a quadrilateral.

7x - 8(-2 + 9) = 112
7x - 8(7) = 112
7x - 56 = 112
7x = 112 + 56
7x = 168
x 168/7
x = 24 <==
