The given expression is undefined when x = 5 OR x = -5
<h3>Undefined expression </h3>
From the question, we are to determine the value of x for which the given expression is undefined
The given expression is
x-4/3x²-75
An expression is undefined when the denominator equals zero
Thus, the expression is undefined when
3x² - 75 = 0
Now, we will determine the values of x in the equation above
3x² - 75 = 0
3x² = 75
x² = 75/3
x² = 25
x = ±√25
x = ±5
Hence, the given expression is undefined when x = 5 OR x = -5

For the first step you need to convert between feet in real life and feet in the cartoon drawing. 1/2 inch in cartoon is 3 feet in real life, so 1 foot in real life was 1/6 inch in cartoon. Her hair was 21 feet in real life, therefore it was 21/6, or 7/2 inches long in the cartoon. For the second step you need to explain what I just said, In your own words! Please do not simply copy down my solution.
4:9
24:x
Set up a proportion
4/9=24/x
4x=216
x=54
a) 54 is your answer
hope this helps, and please give brainliest if it does!
Answer:
B) x = (-3/5)y + 3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
first, subtract 3y from btoh sides:
5x + 3y (-3y) = 15 (-3y)
5x = -3y + 15
Next, divide 5 from both sides:
(5x)/5 = (-3y +15)/5
x = (-3/5)y + 3
B) x = (-3/5)y + 3 is your answer.
