ON = 8x • 8
LM = 7x + 4
NM = x - 5
OL = 3y - 6
OL is congruent & parallel to NM
LM is congruent & parallel to ON
So,
Simplify
subtract 7x from both sides
divide 57 from both sides
Substitute x into equations
NM & OL = -28/57
ON & LM = 4 + (28/57)
LM = 7x + 4
NM = x - 5
OL = 3y - 6
OL is congruent & parallel to NM
LM is congruent & parallel to ON
So,
Simplify
subtract 7x from both sides
divide 57 from both sides
Substitute x into equations
NM & OL = -28/57
ON & LM = 4 + (28/57)
For this case we have that, by definition, the domain of a function is given by all the values for which the function is defined.
Having said that, we have the following function:
It is not defined when the denominator is equal to 0. That is:
Thus, the domain of r (x) is given by all real numbers except 1.
Answer:
all real numbers except 1.
