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 int(-7.5, 0)
y int (0, 5.5)
Step-by-step explanation:
Answer:
x= - 3.5
y= - 6.5
Step-by-step explanation:
-3x+y = 4 equation 1
-9x + 5y = -1 equation 2
and
equation 1 can be written as
y = 4+ 3x
so put this in equation 2
-9x + 5 ( 4+ 3x) = -1
-9x +20 +15x = -1
6x = -21
X= -21 ÷ 6
X = - 3.5
so put this value of x in equation 1 to find value of y
-3 ( -3.5) + y = 4
10.5 + y = 4
y = 4 - 10.5
Y = - 6.5
