Which statement best describes the excluded values of a rational expression?
a- the number of excluded values of a rational expression cannot exceed the degree of the numerator.
b- the number of excluded values of a rational expression cannot exceed the degree of the denominator.
c- the number of excluded values of a rational expression cannot exceed the sum of the degrees of the numerator and denominator.
d- the number of excluded values of a rational expression cannot exceed the difference in the degrees of the numerator and denominator.

b. The number of excluded values of a rational expression cannot exceed the degree of the denominator.

Step-by-step explanation:

A rational expression is a fraction in which the numerator and the denominator are polynomials. The excluded values of a rational number are that values which make denominator zero.They are basically the zeroes of the polynomial of denominator.So,the number of excluded values can't exceed the degree of the denominator.

Here is  a rational expression  

where the denominator is

⇒x=-2,+2 are zero of polynomial

i.e. -2 and 2 are the excluded values for the whole rational expression.

Step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
