To rewrite the expression -2(n-7) using the distributive property, we need to distribute the -2 to both terms inside the parentheses. The distributive property states that for any numbers a, b, and c:

a(b + c) = ab + ac

Applying this property to the given expression:

-2(n-7) = -2 * n + (-2) * (-7)

Simplifying further:

-2(n-7) = -2n + 14

Therefore, the rewritten expression is -2n + 14.

The maximum APR with quarterly compounding that the borrower will accept from a lender is 16.132%.

To convert the maximum effective monthly rate of 1% into an APR with quarterly compounding, we can use the formula:

\(APR = [(1 + \dfrac{r}{n})^n - 1] \times 4\)

Where r is the effective monthly rate and n is the number of compounding periods per year. In this case, we want to find the maximum APR with quarterly compounding that the borrower will accept, so we can substitute r = 1% and n = 3:

\(APR = ((1 + \dfrac{0.01}{3})^3 - 1) \times 4\)

APR = (1.0100333³ - 1) x 4

APR = 0.04033 x 4

APR = 0.16132 or 16.132%

Therefore, the maximum APR with quarterly compounding that the borrower will accept from a lender is 16.132%.

The measure of the minor arc m∡rv = 111°

Recall that according to the principle of angle of intersecting secants, (a-b)/2 = c

Where a = ∡RV
b = ∡SU = 37°:

and c = ∠T (the angle between intersecting secants.

Thus, if (a-b)/2 = c, and b = c = 37 degrees, then we can substitute these values into the equation to get:

(a - 37) / 2 = 37

Multiplying both sides by 2 gives:

a - 37 = 74

Adding 37 to both sides gives:

a = 111

Therefore, a is equal to  m∡rv = 111°.

(D) |k - 7| < - 6 has no solution is not a true statement because an absolute value can never be negative, so the inequality has no solution.

Inequality refers to the state of being unequal or not equal in some respect. It can refer to various forms of disparities or differences, such as differences in income, wealth, education, opportunities, health, or social status, among others. Inequality can occur between individuals, groups, communities, or nations, and it can be caused by various factors, such as discrimination, historical legacies, social structures, policies, or economic systems. Inequality is often considered a social problem because it can lead to social tension, unrest, and injustice, as well as undermine economic growth and human development.

Answer:

Left 2 units

Step-by-step explanation:

Without knowing what f(x), it is impossible to answer this question. I'll answer assuming a parent function of \(f(x)=x^2\).

In the function \(y=(x-c)^2\), \(c\) represents the phase shift from parent function \(f(x)=x^2\). If \(c\) is positive (e.g. \((x-3)^2\)), then the function shifts to the right however many units \(c\) is. If \(c\) is negative (e.g. \((x+5)^2\)), the function shifts to the left however many units the absolute value of \(c\) is.

In the function \(g(x)=(x+2)^2\), let's find out the value of \(c\):

Format: \(y=(x-c)^2\)

\(g(x)=(x+2)^2=(x-(-2))^2\)

Therefore, \(c=-2\).

Since \(c\) is negative, the function must shift to the left. To find out how many units it shifts to the left, take the absolute value of \(c\):

\(|-2|=\boxed{2\text{ units to the left}}\).

Thus, the graph of \(g(x)=(x+2)^2\) is a translation of the graph \(f(x)=x^2\) by 2 units to the left.

*Note: Once again, this answer is assuming \(f(x)=x^2\) as it is not clarified in the question. If \(f(x)\neq x^2\) and is already shifted, you will need to account for shift. If you believe this is the case, feel free to let me know in the comments.

Therefore, the least common denominator of the two fractions is. \(3(x+4)^2\)

LCD stands for Liquid Crystal Display. It is a type of display technology used in devices such as televisions, computer monitors, smartphones, and digital watches. The LCD display consists of a layer of liquid crystal material sandwiched between two transparent electrodes. The liquid crystal material is responsible for the light modulation which produces the display.

When an electric current is applied to the electrodes, the liquid crystal material changes its optical properties, which allows light to pass through or be blocked. This modulation of light produces the images that we see on LCD screens. LCD displays are known for their high resolution, sharp images, and low power consumption, which make them a popular choice for a variety of electronic devices.

To find the least common denominator (LCD) of the two fractions, we need to factor the denominators of each fraction.

The first denominator x+4 factors as x+4.

The second denominator 3x+12 can be simplified by factoring out the greatest common factor of 3, which is\(3(x+4). So 3x+12 = 3(x+4)\).

Now we have the two denominators in factored form, and the LCD is the product of the factors with the highest power of each factor used.

Thus, the LCD is:

\(LCD = 3(x+4) * (x+4) = 3(x+4)^2\)

To convert the first fraction to an equivalent fraction with the same denominator, we need to multiply both the numerator and denominator by 3:

\(9x/x+4 = 9x/x+4 * 3/3 = (27x)/(3x+12)\)

To convert the second fraction to an equivalent fraction with the same denominator, we need to multiply both the numerator and denominator by (x+4):

\(17/3x+12 = 17/3x+12 * (x+4)/(x+4) = (17(x+4))/(3(x+4)^2)\)

Now both fractions have the same denominator, which is \(3(x+4)^2\).

So, the equivalent fractions are:

\((27x)/(3x+12) = (27x * (x+4))/(3(x+4)(x+4)) = (27x(x+4))/(3(x+4)^2)\)

\((17(x+4))/(3(x+4)^2)\)

Using a system of equations, it is found that:

1.

2. Tables are good for summarized data, that is, containing a few pairs of input - outputs solutions.

A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.

In the context of this problem, the variables are given as follows:

Considering that they want to raise $100, and the prices of $4 for each chocolate chip and of $2 for each brownie, the equation is:

4x + 2y = 100.

In intercept form, the equation is given by:

2y = 100 - 4x

y = -2x + 50.

When x = 10, the solution of the system for y is given as follows:

y = -2(10) + 50 = -20 + 50 = 30.

Hence one possible solution is (x,y) = (10,30), meaning that she can sell 10 chocolate chips and 30 brownies.

In this question, we are given pairs of input-output that satisfy the given condition, hence tables are more appropriate than graphs.

Answer:

1. 100=4x+2y and y = -2x+50

X=19, and Y=12

2. Graphs are better for showing trends. tables are better for showing precise data.

Step-by-step explanation:

Luna makes $4 per cookie, so her equation for her income is 4x. Miles makes $2 per cookie, so his equation is 2y. Since they want to make $100, that means that 100 = 4x+2y. Then put this in y-inercept form. Or, y=-2x+50

So now I need to find a solution for y = -2x+50, or 100=4x+2y. One way to do this is through substitution. We can use 12 as the y input.

​

This would mean that miles sold 12 brownies.  Then,  ---> = 19.

​

Therefore, a solution is x=19 and y=12. Meaning Luna sold 19 cookies and Miles sold 12 cookies. (19,12)

The length of the other two sides are 4m and 5m

Using the Pythagorean theorem, we have that the square of the hypotenuse sides is equal to the sum of the squares of the other two sides of the triangle

This is represented as;

x² = y² + z²

From the information given, we have that;

z = 3m

x = x + 1

y = x

Substitute the values, we get

(x + 1)² = x² + 3²

Find the squares

(x + 1) ² = 9 + x²

expand the bracket

(x + 1) ( x + 1) - x² = 9

x² + x + x + 1 - x² = 9

collect like terms

2x = 8

x = 4

Then,

x + 1 = 5

x = 4

The total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.

To determine the number of possible outcomes, we need to consider the number of outcomes for each event and then multiply them together.

1. Picking a marble: Let's assume there are n marbles to choose from. If there are n marbles, then the number of outcomes for this event is n.

2. Rolling a die: A standard die has 6 sides numbered 1 to 6. Therefore, the number of outcomes for this event is 6.

3. Picking a card: A standard deck of cards has 52 cards. Hence, the number of outcomes for this event is 52.

To find the total number of possible outcomes, we multiply the number of outcomes for each event together:

Total number of outcomes = (number of outcomes for picking a marble) × (number of outcomes for rolling a die) × (number of outcomes for picking a card)

Total number of outcomes = n × 6 × 52

Therefore, the total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.
