Rational expressions
(for what value of x is the rational expression below undefined)?
3x-12/9-x

For x = 9  the given rational expression  is undefined.

Step-by-step explanation:

Given rational expression

We have to find for what value of x is the given rational expression is undefined.

Consider the given rational expression

For a fractional expression to be undefined the denominator has to be zero, so that

Thus, for the given expression

Denominator is 9-x

Thus, to make it not defined, Put 9 - x = 0

⇒ x = 9

Thus, for x = 9  the given rational expression  is undefined.

what do you need me to answer?

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
