Answer: x= 6

Step-by-step explanation:

Since the shape is a parallelogram, the angles will either be equal to each other or add up to 180.  

You can see they do not look the same so they add up to equal 180

12x + 3 +105 = 180

12x + 108 = 180

12x = 72

x = 6

Answer:

x = -2

Step-by-step explanation:

-11x + 14 = 36

-11x = 36 - 14

-11x = 22

x = 22/-11

x = -2

Answer:

-2

Step-by-step explanation:

1. Subtract 14 from both sides.

2. Simplify 36−14 to 22.

3. Divide both sides by -11.

4. Simplify 22/11 to 2.

bearing in mind that the sum of all interior angles in a polygon is

180(n - 2)    n = number of sides in the polygon

a DECAgon, DECA=10, has 10 sides, and thus the sum of all its interior angles is 180(10 - 8) = 1440.

\(\bold{120+140+160+130+125+140+165+160+140+v=1440}\)

\(\bold{1275+v=1440 \implies v=1440-1275 \implies v=165}\)

Answer:

x = -5 or 1/2

Step-by-step explanation:

From the question,

3x²+12x-7 = x²+3x-2

Collect like terms

3x²-x²+12x-3x-7+2 = 0

2x²+9x-5 = 0

Using factorization method to solve the quadratic equation

2x²+10x-x-5 = 0

(2x²+10x)-(x+5) = 0

2x(x+5)-1(x+5) = 0

(x+5)(2x-1) = 0

Either,

x+5 = 0

x = -5

or,

2x-1 = 0

2x = 1

x = 1/2.

Therefore,

x = -5 or 1/2

Count(POi > M) represents the number of police officers whose income is greater than the median income, and Count(Mi > M)

To determine how many individuals make more than the median income in Holly Springs, we would need information about the incomes of the police officers and musicians. Without this data, we cannot provide an exact answer.

However, I can provide you with the mathematical equation to calculate the number of individuals who make more than the median income, given the incomes of each group.

Let's assume that the incomes of police officers are sorted in ascending order, and the incomes of musicians are also sorted in ascending order. The median income is the income value in the middle when the incomes are arranged in increasing order.

Let's say the median income is M.

To find the number of individuals who make more than the median income, you would need to count the number of police officers and musicians whose income is greater than M.

If you have the incomes of the police officers and musicians, denoted as PO1, PO2, ..., PO60 for police officers and M1, M2, ..., M18 for musicians, you can use the following equation:

Number of individuals making more than the median income = Count(POi > M) + Count(Mi > M)

Here, Count(POi > M) represents the number of police officers whose income is greater than the median income, and Count(Mi > M) represents the number of musicians whose income is greater than the median income.

In the C-Chart, the value of the C-bar, representing the average count of nonconformities per unit, does not have to be an integer. So, the statement 'In the C-Chart, the value of C-bar must be an integer' is false.

In the C-Chart (also known as the Count Chart), the value of C-bar does not necessarily have to be an integer.

C-bar represents the average count of nonconformities per unit. It can be a decimal value, especially when dealing with continuous data or when the sample size is large.

The C-Chart is a statistical process control chart used to monitor the count of nonconformities in a process. It helps to determine if the process is in control or if there are any unusual patterns or trends in the nonconformity counts. The C-bar value is typically calculated as the total number of nonconformities divided by the number of units or observations.

So, the value of the C-bar in the C-Chart can be a decimal or fractional value, not necessarily an integer.

The coordinates of the kink point are (x1,x2) = (400,200).

Part a)The budget constraint is x1 + x2 = 400. The optimization problem is Max x1x2 subject to x1 + x2 = 400.

Using the Lagrange method, the problem becomes:

f(x1,x2,λ) = x1x2 + λ(400 − x1 − x2)

Taking the first-order condition, we get: ∂f/∂x1 = x2 − λ = 0;

∂f/∂x2 = x1 − λ = 0;

∂f/∂λ = 400 − x1 − x2 = 0

Solving these equations simultaneously, we get x1 = x2 = 200.

Hence, John's optimal consumption bundle is (x1,x2) = (200,200).

To illustrate this optimal consumption bundle, we can use a graph with x1 on the x-axis and x2 on the y-axis.

The budget line is x1 + x2 = 400, and the indifference curves are given by u(x1,x2) = x1x2.

These indifference curves are rectangular hyperbolas, which can be represented by isoquants.

The optimal consumption bundle is the point of tangency between the budget line and the highest attainable isoquant.

The optimal consumption bundle is at point A.

Part b)Suppose the government implements a subsidy program for drinks.

Specifically, for each dollar that John spends on drinks, the government will give John $0.50 in cash, with the restriction that the total amount of cash that John receives from the government cannot exceed $100.

Since John's utility function is separable, his marginal rate of substitution is constant. Hence, the slope of his budget line is also constant.

The price of x1 (drinks) is reduced by half due to the subsidy, while the price of x2 (other things) remains the same.

The budget line becomes x1/2 + x2 = 400 + 100.

Since the subsidy is capped at $100, John can receive a maximum of $200 in cash from the government.

Hence, if John spends $400 on drinks, he will receive $200 from the government and his expenditure on drinks will be reduced to $200.

Therefore, the maximum amount that John can spend on drinks is $400.

The coordinates of the kink point can be determined as follows:

Since John's income is $400 and the price of x2 is $1, he can buy 400 units of x2.

The price of x1 is $0.50.

Hence, he can buy 800 units of x1 if he spends all his income on drinks.

The maximum amount of cash he can receive from the government is $200.

Hence, if he spends $400 on drinks, he will receive $200 from the government and his expenditure on drinks will be reduced to $200.

Therefore, the maximum amount that John can spend on drinks is $400.

The kink point is the point at which John spends all his cash subsidy and his own money on drinks.

Therefore, the coordinates of the kink point are (x1,x2) = (400,200).

The coordinates of the midpoint M are (-1, 4).

To find the midpoint M of the line segment AB with endpoints A(2, 1) and B(-4, 7), we can use the midpoint formula.

The midpoint formula states that the coordinates of the midpoint M(x, y) of two points A(x₁, y₁) and B(x₂, y₂) can be found by taking the average of their respective x-coordinates and y-coordinates:

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

Let's apply the formula to find the midpoint M of AB:

x = (2 + (-4)) / 2

= -2 / 2

= -1

y = (1 + 7) / 2

= 8 / 2

= 4

Therefore, the coordinates of the midpoint M are (-1, 4).

To find the midpoint of a line segment, we take the average of the x-coordinates and the average of the y-coordinates. So, for the line segment AB with endpoints A = (2, 1) and B = (-4, 7), the midpoint M is:

→ M = ((2 + (-4)) / 2, (1 + 7) / 2)

M = (-1, 4)

Answer:

The correct option is Option C

Step-by-step explanation:

We are given the lines: \(y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}\)

The lines are perpendicular if they have opposite slopes i,e \(m_1=-\frac{1}{m_2}\)

In line 1 the slope is \(-\frac{4}{5}\) (Comparing with slope-intercept form \(y=mx+b\) we get the value of m=-4/5)

In line 2 the slope is \(-\frac{5}{4}\) (Comparing with slope-intercept form \(y=mx+b\) we get the value of m=-5/4)

The opposite reciprocal of -4/5 is 5/4  

So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.

If the lines are parallel there slope must be same. Hence lines are not parallel as well.
