Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
Answer:

Step-by-step explanation:
They both (36 and 45) go into 9. Divide them both by 9.

Answer:
x = 2√13.
Step-by-step explanation:
Using the Pythagoras theorem:
14^2 = x^2 + 12^2
x^2 = 14^2 - 12^2
x^2 = (14 + 12)(14 - 12) = 52
x = √52
x = √4*√13
x = 2√13.
Answer:

Step-by-step explanation:
we would like to find the inverse of the following function:

to do so substitute y for f(x):

interchange variables:

cancel 9 from both sides:

square both sides:

add 4 in both sides:

divide both sides by 4:

substitute back:

and we're done!
The domain is the input values, which would be the numbers that have the arrows pointing away from them.
This would be the 4 numbers in the oval on the left side.
The answer is B. {1,2,3,4}
