Mathematics

<u>Answer:</u>

more than one variable (two or more)


<u>Explanation:</u>

<u>Literal equations</u> are used to represent a known quantity/value using unknown values.


Now,<u> if we have only one variable</u>, then this variable will no longer be unknown as it will be equal to the known quantity. This means that the equation will not be literal.

<u>Example:</u>

Number of tickets is 25.

x = 25 where x is the number of tickets


If we have<u> two variable</u>, neither of them will be known. This means that the equation will be literal.

<u>Example:</u>

Number of apples added to number of bananas is 15.

x + y = 15

where x is the number of apples and y is the number of bananas, neither of them is known.


<u>Based on the above,</u> the literal equation must have more than one variable (two or more)


Hope this helps :)

Answer – Two or more variables (In other words, More than one variable)

In simple terms, literal equations are equations containing two or more variables; at least one independent variable and one dependent variable. In essence, all literal equations have more than one variable.

Is the product of two integers positive, negative, or zero? How can you tell?
marishachu [46]

When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12.

In 1980, the average cost of a pack of cigarettes was $0.88. In 2000, the average cost was $5.31 per pack.
yan [13]

Answer:

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average <em>rate of change</em> is <em>slope</em>.

Step-by-step explanation:

The average rate of change of the cost of a pack (r), in monetary units per year, is equal to the change in the average cost of a pack (\Delta c), in monetary units, divided by the change in time (\Delta t), in years. Then, the average rate of change is:

r = \frac{\$\,5.31-\$\,0.88}{2000-1980}

r = \$\,0.22\,\frac{1}{yr}

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average <em>rate of change</em> is <em>slope</em>.
