Explanation:
I just put the input where the variable is
Answer:
one x-intercept.
Transformation: shift to the right 8 units.
Step-by-step explanation:
The parent function is 
To find the number of x-intercepts, we equate the function to zero.


There is only one x-intercept at t=0.
The transformed function is

This function is obtained shifting the parent function 8 units to the right.
The x-intercept will now be at t=8.
Hence the image function also has one x-intercept.
Answer:
12.66 
Step-by-step explanation:
Given the dimensions of the room are
=
and
=
.
The area of the room =
Area=
Area=72.33 
The area of the carpet=85 
The area of carpet left= Total area of carpet - the area of the room
The area of carpet left= 85-72.33=12.66 
Means the number you can use
remember we can't divide by zero
domain is x^2-9
set to zero to find values we can't use
x^2-9=0
x^2=9
x=+/-3
domain=all real numbers except -3 and 3
