Answer:
Step-by-step explanation:
- For a horizontal compression, we multiply whole numbers greater than 1 in front of
of the given function. - For horizontal expansion, we multiply by the reciprocal of the number for horizontal compression, in front of of the function.
For example,
If we wanted to <u>horizontally compress</u> 
, we would multiply by 4 to get 
, and
if we wante to <u>horizontally expand</u> , we would multiply by 
to get 
Since this question asks for horizontal compression, we multiply the of the function by 4. So the function we need is 
. The second choice is correct.
Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
5x < 20
Step 2: Solve for <em>x</em>
- Divide both sides by 5: x < 4
Here we see that any number less than 4 will work. So numbers like 3, 0, or even -12587235897 would work.
Answer:
The car going 1232 inches per second because 65 miles per hour is only 1144 inches per second.
Step-by-step explanation:
-5x -3x + 7x
-8x + 7x
-x
Thus, second option is correct.
