The function (g+h)(n-4) is the sum of the function g(n-4) and h(n-4) will be written as (g+h)(n-4) = n² - 7n + 9.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The functions are given below.

g(n) = n² + 4n

h(n) = - 3n - 3

The function (g+h)(n) is calculated as,

(g+h)(n) = g(n) + h(n)

(g+h)(n) = n² + 4n - 3n - 3

(g+h)(n) = n² + n - 3

Put n = n - 4, then we have

(g+h)(n-4) = (n - 4)² + (n - 4) - 3

(g+h)(n-4) = n² + 16 - 8n + n - 4 - 3

(g+h)(n-4) = n² - 7n + 9

The function (g+h)(n-4) will be (g+h)(n-4) = n² - 7n + 9.

Answer:

x/7 + 1 = 10

Step-by-step explanation:

x/7 + 1 = 10

The solutions using the graph, observe the x-values where the graph intersects with the corresponding lines: (i) x ≈ -1 and x ≈ 1, (ii) x ≈ -1.5 and x ≈ 1.

To find estimates for the solutions of the given equations using the graph of \(y = 3x^2 - 3x - 1\), we need to analyze the points of intersection between the graph and the corresponding lines.

i) \(3x^2 - 3x + 2 = 2:\)

By subtracting 2 from both sides of the equation, we can rewrite it as:

\(3x^2 - 3x = 0\)

We are looking for the x-values where this equation is satisfied. From the graph, we observe that the parabolic curve intersects the x-axis at two points. These points are approximate solutions to the equation. By visually inspecting the graph, we can estimate that the solutions are around x = -1 and x = 1.

ii)\(3x^2 - 3x - 1 = x + 1:\)

By subtracting x + 1 from both sides of the equation, we can rewrite it as:

\(3x^2 - 4x - 2 = 0\)

Again, we can observe from the graph that the parabolic curve intersects the line y = x + 1 at two points. By visually examining the graph, we can estimate the solutions to be around x = -1.5 and x = 1.

It's important to note that these estimates are based on visual inspection of the graph and are not precise solutions. For accurate solutions, algebraic methods such as factoring, completing the square, or using the quadratic formula should be employed.

However, by using the graph, we can make approximate estimates of the solutions to these equations.

Answer:

1 1/4 cups

Step-by-step explanation:

3 3/4 cups = 3.75

3.75 x .33333 = 1.25

1.25 = 1 1/4 cups

For events A and B to be independent, the condition that must be true is:
P(A ∩ B) = x * y

The correct condition that must be true if events A and B are independent is:

P(A ∩ B) = P(A) x P(B).

where P(A) is the probability of event A, P(B) is the probability of event B, and P(A ∩ B) is the probability of both events A and B occurring together.

In other words, if events A and B are independent, then the probability of both events occurring together is equal to the product of their individual probabilities.

When two events A and B are independent, the following condition must be true:
P(A ∩ B) = P(A) * P(B)
In your case, the probability of event A is x, and the probability of event B is y.

Therefore, the correct answer is:

P(A ∩ B) = x*y

Let's solve your equation step-by-step.

−88=−3(4m+5)−(1−3m)

Step 1: Simplify both sides of the equation.

−88=−3(4m+5)−(1−3m)

−88=−3(4m+5)+−1(1−3m)(Distribute the Negative Sign)

−88=−3(4m+5)+(−1)(1)+−1(−3m)

−88=−3(4m+5)+−1+3m

−88=(−3)(4m)+(−3)(5)+−1+3m(Distribute)

−88=−12m+−15+−1+3m

−88=(−12m+3m)+(−15+−1)(Combine Like Terms)

−88=−9m+−16

−88=−9m−16

Step 2: Flip the equation.

−9m−16=−88

Step 3: Add 16 to both sides.

−9m−16+16=−88+16

−9m=−72

Step 4: Divide both sides by -9.

−9m/−9 = −72/−9

The correct answer is option c, means that 12 people scored at or below a score of 72 on the test having a cumulative frequency of 12.

Cumulative frequency refers to the total number of observations or individuals that fall at or below a certain value in a dataset. In this case, a cumulative frequency of 12 (cf = 12) for a test score of 72 means that there are 12 people who scored at or below a score of 72 on the test. Options a, b, and d are incorrect interpretations of the cumulative frequency.

Option a suggests that 72 people scored at or below a score of 12, which is not accurate based on the given information. Option b implies a percentage, which is not directly indicated by the cumulative frequency value. Option d suggests a percentage of people scoring at or below a score of 72, which again is not supported by the information provided. Therefore, the correct interpretation is that 12 people scored at or below a score of 72 on the test (option c).

Answer:

x = 7.

Step-by-step explanation:

-18 = 6 (x - 10)

-18 = 6x - 60

6x = -18 + 60

6x = 42

x = 42/6 = 7.

Answer:

\(x=7\)

Step-by-step explanation:

\(-18=6(x-10)\)

Use distributive property.

\(-18=6x-60\)

Add 60 on both sides.

\(-18+60=6x\)

\(42=6x\)

Divide by 6 on both sides.

\(\frac{42}{6} =x\)

\(7=x\)

Another method.

\(-18=6(x-10)\)

Divide by 6 on both sides.

\(-18/6=x-10\)

\(-3=x-10\)

Add 10 on both sides.

The values are: -9, 7, -2, Undefined, Undefined, 8, Undefined, Undefined.

Let's match each expression with its corresponding value:

Expression: -9

Value: -9

Expression: 7

Value: 7

Expression: -2

Value: -2

Expression: Undefined

Value: Undefined

Expression: h(3.999)

Value: Undefined

Expression: h(4)

Value: 8

Expression: h(4.0001)

Value: Undefined

Expression: h(9)

Value: Undefined

Now let's explain the reasoning behind each value:

The expression -9 represents the number -9, so its value is -9.

Similarly, the expression 7 represents the number 7, so its value is 7.

The expression -2 represents the number -2, so its value is -2.

When an expression is labeled as "Undefined," it means that there is no specific value assigned or that it does not have a defined value.

For the expression h(3.999), its value is undefined because the function h(x) is not defined for the input 3.999.

The expression h(4) has a value of 8, indicating that when we input 4 into the function h(x), it returns 8.

Similarly, the expression h(4.0001) has an undefined value because the function h(x) is not defined for the input 4.0001.

Lastly, the expression h(9) also has an undefined value because the function h(x) is not defined for the input 9.

Assuming that the rates are constant, we can see that Tom can paint the fence in 7.5 hours.

Here we will use equations of the form:

(rate at which person x paints)*(time) = 1 fence painted.

We know that Chuck can paint a fence in 5 hours, then if C is the rate (assuming this is constant), we can write:

C*5 hours = 1 fence

C = (1/5) fences per hour.

And let's say that Tom's rate is T.

When they work together, the rate is:

(C + T)

And they can paint the fence in 3 hours, then:

(C + T)*3 hours = 1 fence

Replacing the value of T we will get:

( 1/5 fences per hour + T)*3 hours = 1 fence

1/5 fences per hour + T = 1/3 fences per hour.

T = (1/3 - 1/5) fences per hour

T = (5/15 - 3/15) fences per hour

T = 2/15 fences per hour.

Then Tom paints the fence in:

(15/2) hours = 7.5 hours.

Kerys should substitute the values of k from 0 to 4 (inclusive) in the binomial theorem expression to expand the binomial (2x + y)⁴.

The binomial theorem states the principle for expanding the algebraic expression (x + y)ⁿ and describes it as the total of the phrases involving the unique exponents of the x and y variables. Each word in a binomial expansion has a coefficient, which is a numerical value.

The binomial theorem states that the expansion of the binomial \({(a + b)}^{n}\) is given by the formula:

\(\displaystyle\sum_{k = 0}^{n}{\begin{pmatrix} n \ k \ \end{pmatrix}a^{n - k}b^{k}}\)

The variable n represents the power to which the binomial is raised, in this case n = 4.

The variable k is the exponent of the second term in the binomial (b), in this case y.

So, with k = 0, the term will be aⁿ = (2x)⁴, with k = 1, the term will be

\(a^{(n-1)} b = (2x)^3 y\), and so on.

Therefore, he should substitute the values of k from 0 to 4 (inclusive) in the binomial theorem expression to expand the binomial (2x + y)⁴.

The equation that represents h(x) is h(x) = (f(x))(g(x)).

To determine which equation represents h(x), we need to analyze the given table and understand the relationship between the functions f(x), g(x), and h(x).

Since h(x) represents the output values obtained by multiplying f(x) and g(x), we should look for values in the table where h(x) is the product of the corresponding values of f(x) and g(x).

Let's examine the table and compare the values:

x | f(x) | g(x) | h(x)

1 | 3 | 4 | 12

2 | 5 | 2 | 10

3 | 2 | 6 | 12

From the table, we can see that the values in the h(x) column are the products of the corresponding values in the f(x) and g(x) columns. Therefore, the equation that represents h(x) is h(x) = (f(x))(g(x)).
