Answer:

#4 is not a function because not every x-value corresponds with only one y-value

Step-by-step explanation:

Answer:

E. x = 4

F. x = -2

Step-by-step explanation:

Asymptotes occur when you have an undefined (a divide by 0 error). So x in the denominator can't equal zero. The 2 values that make the denominator zero are 4 and -2.

We must solve the following equation for x:

We can square both sides of the equation:

Then we substract 9 from both sides:

Now we have a quadratic expression equalized to 0. The solutions to this equation are given by the quadratic solving formula. For an equation ax²+bx+c=0 the quadratic formula states that its solutions are:

For the equation we found before we have a=1, b=-12 and c=35. Then its solutions are:

So there are two solutions:

Then the answers are x=5 and x=7.

Answer:

\(9m^2 + 17m- 9\)

Step-by-step explanation:

Given

\(7m^2 + (2m - 1)(m + 9)\)

Required:

Simplify

We start by opening the bracket

\(7m^2 + (2m(m + 9) - 1(m + 9))\)

\(7m^2 + 2m^2 + 18m - m - 9\)

Collect Like Terms

\(9m^2 + 17m- 9\)

Hence, the equivalent expression is \(9m^2 + 17m- 9\)

If each person eat one quarte (1/4) of the cake, this means that only 4 people can eat from one cake, as:

Each person eats 2 pieces of 1/8 of the cake, as 2*1/8=2/8=1/4.

Answer: 4 people can eat cake.

Answer(s):

What is the dependent variable of an equation?

The dependent variable of an equation is the variable that is completely isolated on one side.

What is the independent variable of an equation?

The independent variable is the variable that is not isolated. The independent variable can either have a cooeficient or has some operation (+ - × ÷) included on that side of the equation.

Determining the independent and dependent variable

In this equation, we can see that "v" is completely isolated on one side and "t" has a cooeficient of 68. Thus, the dependent variable is "v" and the independent variable is "t".

Answer:

(2, –3) is a solution to the system of linear equations.

Step-by-step explanation:

Given: Equations:

3x - y = 9 --------(1),

4x + y = 5 --------(2),

Add Equation (1) + Equation (2),

3x + 4x = 9 + 5

7x = 14  ( Combine like terms )

x = 2   ( Divide both sides by 7 ),

From equation 1:

3(2) - y = 9

6 - y = 9

-y = 9 - 6    ( Subtraction 6 on both sides )

-y = 3

y = - 3     ( Multiplying -1 on both sides )

After eight years, the value of Edward's home increased by $24,386.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Edward purchased his home for $89,000.

For the first three years after he moved in the real estate market was very lively, so his property value grew by 4.8% every year.

And,  For the next five years, the market slowed down somewhat, and his property value grew by 2.6% every year.

Now,

After three years, the value of Edward's home increased by,

⇒ 3 × (4.8% of $89,000)

⇒ 3 × (4.8/100 × 89,000)

⇒ 3 × 4,272

⇒ $12,816

And, After five years, the value of Edward's home increased by,

⇒ 5 × (2.6% of $89,000)

⇒ 5 × (2.6/100 × 89,000)

⇒ 5 × 2,314

⇒ $11,570

Thus, After eight years, the value of Edward's home increased by,

⇒ $12,816 + $11,570

⇒ $24,386

A child's ability to learn to read is the result of both natural cognitive development and environmental factors, with the interaction between nature and nurture being important for reinforcing the learning process.

Learning to read is a complex process that involves both nature (maturation) and nurture (environmental factors). Here are some reasons why:

Maturation: There is a natural process of cognitive development that occurs in children, which enables them to learn to read. For example, their brains develop the ability to recognize and differentiate between sounds, which is necessary for decoding words.

Nurture: The environment in which a child grows up can also have a significant impact on their ability to learn to read. For example, exposure to books, reading materials, and literacy-rich environments can enhance a child's vocabulary and comprehension skills.

Interaction: Finally, the interaction between nature and nurture is also important. For example, a child's natural curiosity and motivation to learn may be influenced by the support and encouragement of caregivers, teachers, and peers.

The total number of donations in September representing total collected amount $479.25 at the end of September month is equal to 14.

Let x be the number of donations Lukas collects in the month of September.

Collection of donations by Lukas in the month of August = $230.75

Total donations collected by Lukas at the end of September month = $479.25

In September, Lukas collected $17.75 for each donation,

And he collected x donations.

The total amount of donations he collected in September is equal to,

17.75x

The total amount of donations Lukas collected by the end of September is written as,

230.75 + 17.75x = 479.25

Subtract 230.75 from both sides of the equation we get,

⇒ 17.75x = 248.50

Divide both sides of the equation by 17.75  we have,

⇒ x = 14

Therefore, the total number of donations collected by Lukas in September month is equal to 14.

The equation in the form (x + a)² = b is (x + 2)² = 16

The equation is given as:

x² + 4x = 12​

Take the coefficient of x

k = 4

Divide by 2

k/2 = 2

Square both sides

(k/2)² = 4

Add this result to both sides of x² + 4x = 12​

x² + 4x + 4 = 12​ + 4

Evaluate the sum

x² + 4x + 4 = 16

Express as a perfect square

(x + 2)² = 16

Hence, the equation in the form (x + a)² = b is (x + 2)² = 16

Therefore, in about 15 years and 2 months, the senior class will have about 100 students.

An equation is a statement that expresses the equality of two mathematical expressions using mathematical symbols such as variables, numbers, and mathematical operations. The equality is represented by an equal sign "=" between the two expressions. Equations are used to represent mathematical relationships and solve problems in various fields such as physics, chemistry, engineering, and economics.

Given by the question.

Let P be the initial population of the senior class in the high school, and r be the rate of decrease in population per year (in decimal form).

Then, we can write the following equation to represent the situation:

P\((1-r)^{n}\) = 100

We know that the current population of the senior class is 320, so we can substitute these values into the equation:

320\((1-0.07)^{n}\) = 100

Simplifying the equation, we get:

\(0.93^{n}\) = 0.3125

Taking the natural logarithm of both sides, we get:

n ln (0.93) = ln (0.3125)

Dividing both sides by ln (0.93), we get:

n = ln (0.3125) / ln (0.93)

Using a calculator, we find that n is approximately equal to 15.21 years.

To calculate the net gain or loss, we need to consider both the realized and unrealized components. Therefore, the net gain/loss is -$20,000. This indicates a net loss of $20,000.

The net gain or loss is calculated by adding the realized gains or losses and the unrealized gains or losses:

Net Gain/Loss = (Realized Gain/Loss) + (Unrealized Gain/Loss)

Given the information provided:

Realized Loss = $40,000

Realized Loss = $10,000

Unrealized Gain = $30,000

Net Gain/Loss = (-$40,000) + (-$10,000) + $30,000

Net Gain/Loss = -$50,000 + $30,000
