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

Bill wants to rent a car.Rental Company A charges $35 per day plus $0.10 per mile driven.Rental Company B charges $25 per day pl
zlopas [31]

Answer:

m = 200 miles

Step-by-step explanation:

Rental Co. A:  A(m) = $35 + ($0.10/mile)(m), where m is the number of miles driven

Rental Co. B:  B(m) = $25 + ($0.15/mile)(m)

Set these two dollar amounts equal to each other and solve for m:

$25 + ($0.15/mile)m = $35 + ($0.10/mile)(m).  Combine like terms, obtaining:

($0.05/mile)m = $10; then m = ($10) / ($0.05/mile), or 200 miles.

The price charged by the two companies would be the same when the car has been driven 200 miles.

explain why the amount of propane in a grill’s tank and the time spent grilling could represent an inverse variation
Oxana [17]

The obvious answer is because propane is a gas at room temperature, while 2-propanol is a liquid at room temperature.

That happens because the intermolecular forces that exist between 2-propanol, or isopropyl alcohol, molecules are stronger than those that exist between propane molecules.

Answer:

x=3

y=-4

Step-by-step explanation:

4x+5y=-8 ----------- (1)

-4x-4y=4 -----------(2)

Adding equation (1) and (2)

4x+5y-4x-4y=-8+4

y=-4

Substitute y=-4 in equation (1) or (2)

4x+5(-4)=-8

4x-20=-8\\4x=-8+20\\4x=12\\x=3
