The requried complete system of equation is given as -2x + y = -5 and y = -x + 10.

A system of simultaneous equations, also known as a system of equations, is a set of two or more equations that must be solved at the same time. In a system of two equations, for example, the solution is the set of values of the variables that satisfy both equations simultaneously.

Here,
Given equation are
_x + y = −5 - -- - - -(1)

y = −x + _ - - - - - (2)

Now,
Let the coefficient of x in equation 1 is m and the intercept of equation 2 be y,

In equation 1,
Put the given points (5, 5)
m(5) + 5 = - 5
5m = -10
m = -2

Now,
Put the same point equation 2 with C
5 = -5 + C
C = 10

Thus, the requried complete system of equation is given as -2x + y = -5 and y = -x + 10.

Answer:

Step-by-step explanation:

To calculate the percentage increase in the estimated number of millionaire households from 2017 to 2018, we need to follow these steps:

Determine the estimated number of millionaire households in 2017 and 2018. Let's call these numbers A and B, respectively.

Subtract the 2017 number from the 2018 number: B - A = C

Divide the result from step 2 by the 2017 number: C / A = D

Multiply the result from step 3 by 100 to convert it to a percentage: D * 100 = E

Round the result from step 4 to the nearest tenth of a percent.

In this case, we are given the percentage increase, so we can skip steps 1-4 and simply round the given percentage increase to the nearest tenth of a percent.

As per the probability, the value of E(X) is option (a) 0.8

In statistics, the expected value or mean is a measure of central tendency that represents the average outcome of a random variable over an infinite number of trials.

To find the expected value of X, we need to calculate the probability of each possible outcome and multiply it by its corresponding value. In this case, the possible outcomes are 0 and 1, and their probabilities can be calculated as follows:

The probability of drawing a 0 is 4/5 because there are 4 zeros in the list and 5 total numbers.

The probability of drawing a 1 is 1/5 because there is only one 1 in the list and 5 total numbers.

Using these probabilities, we can calculate the expected value of X as follows:

E(X) = (0 x 1/5) + (1 x 4/5)

The first term in this equation represents the probability of drawing a 0, multiplied by its value (which is 0), and the second term represents the probability of drawing a 1, multiplied by its value (which is 1). Simplifying this equation gives:

E(X) = 4/5 =0.8

Therefore, the answer to this problem is (a) 0.8, since the expected value of X is 0.8 of the possible outcomes.

Answer:

Step-by-step explanation:

here's a more detailed explanation:

The assistant received a raise of 10%, which means that their salary increased by 10% of the original salary. The new salary after the raise is given as 47,585.

To find the original salary before the raise, we need to reverse the effect of the raise. To do this, we divide the new salary by the factor that represents the increase, which is 1 plus the raise as a decimal.

The raise as a percentage is 10%, which is equivalent to 0.10 as a decimal. Therefore, the factor that represents the increase is 1 + 0.10 = 1.10.

We can now use this factor to find the original salary by dividing the new salary by the factor:

Original salary = New salary / (1 + Raise as a decimal)

Original salary = 47,585 / (1 + 0.10)

Original salary = 47,585 / 1.10

Original salary = 43,259.09

So the salary before the raise was 43,259.09.

The first equation 3(3x - 4) = 24 can be solved for x as follows:

3(3x - 4) = 24

9x - 12 = 24

9x = 36

x = 4

So, if Messi hit the target, he would score 4 points.

The second equation 6.8 (2.3x + 5.7) = 132.6 can be solved for x as follows:

6.8 (2.3x + 5.7) = 132.6

2.3x + 5.7 = 132.6 / 6.8

2.3x + 5.7 = 19.55

2.3x = 13.85

x = 6

So, if Ronaldo hit the target, he would score 6 points.

The approximate length of the guy wire supporting the radio tower, as determined using trigonometry with the given information of a 45 degree angle and a height of 145 feet up the tower, is 145 feet.

We can use trigonometry to solve this problem. Let's call the length of the guy wire "x". The opposite side of the right triangle formed by the guy wire and the ground is 145 feet (the height of the tower where the guy wire is attached), and the angle opposite the guy wire is 45 degrees.

Using the trigonometric function tangent, we can set up the following equation:

[tex]tan(45)[/tex] = opposite / adjacent

where "opposite" is 145 feet and "adjacent" is the length of the guy wire, x. Simplifying this equation, we get:

1 = 145 / x

Multiplying both sides by x, we get:

x = 145

Therefore, the length of the guy wire is approximately 145 feet to the nearest tenth.

3) 0.3 + 2.7 = 6

Answer:

Step-by-step explanation:

The correct answer is D. m∠6 + m∠7 = 180°.

When a transversal cuts two parallel lines, corresponding angles are equal and alternate interior angles are supplementary. This means that the sum of alternate interior angles is equal to 180°. In this diagram, ∠6 and ∠7 are alternate interior angles, so it is necessarily true that m∠6 + m∠7 = 180°.

The other options are not necessarily true. Option A states that m∠1 = m∠7, but this is only true if the two lines being cut by the transversal are perpendicular. Option B states that m∠3 = m∠6, but this is only true if the two lines being cut by the transversal are parallel. Option C states that m∠5 + m∠8 = 90°, but this is only true if the two lines being cut by the transversal are perpendicular.

К счастью, другое маленькое дерево поблизости заметило растущее дерево и дало несколько интересных советов о том, как удерживать его распускающиеся листья новыми и интересными способами. Было забавно испытать на других маленьких деревьях множество различных способов расположения листьев. Другие маленькие деревья вскоре заметили это и начали поворачивать свои немногочисленные листья под углом. Другие маленькие деревья могли лишь слегка приподнять свои листья.

Растущее дерево решило, что будет немного приподнимать листья на радость другим деревьям. Но, в конце концов, все маленькие деревья начали отращивать больше листьев на ветвях, которые тянулись еще дальше. С каждым сезоном многие листья невозможно было приподнять. Некоторые из растущих деревьев продолжали шептаться, в то время как некоторые научились громко смеяться, некоторым, казалось, нравилось плакать и падать духом, а некоторые росли вдали от группы из-за того, как многие времена года влияли на них и на другие деревья и животных вокруг них.

Все растущие деревья заметят это и поднимут головы, чтобы насладиться солнечным светом. Те, кто не обращал внимания на поведение своего родительского дерева, обычно подражали другим растущим деревьям и умудрялись собирать немного солнечного света. Иногда растущее дерево переставало расти, потому что не могло достичь солнечного света. Его листья не будут такими обильными, а его ветви будут тянуться дальше, чтобы быть ближе к солнечному свету других растущих деревьев. По прошествии многих сезонов растущие деревья становились все выше и теперь можно было видеть, что их место среди кроны деревьев было довольно тесным.

The pattern for the hypotenuse in the Pythagorean spiral is √(a² + b²)

The Pythagorean spiral is formed by drawing squares whose side lengths are given by the Pythagorean triples, which are sets of three positive integers (a, b, c) that satisfy the equation a² + b² = c².

In the Pythagorean spiral, the hypotenuse of each square is the diagonal of the square, which is given by the square root of the sum of the squares of the sides. For a square with side lengths a and b, the hypotenuse (diagonal) is given by:

√(a² + b²)

Since the side lengths of each square in the Pythagorean spiral are given by the Pythagorean triples, the hypotenuse of each square can be calculated using the Pythagorean theorem. Therefore, the pattern for each hypotenuse in the Pythagorean spiral is that it is given by the square root of the sum of the squares of the side lengths, where the side lengths are integers that form a Pythagorean triple.

Answer:

So, Darmal needs to work more than 8.96 hours to earn more than $128.

Step-by-step explanation:

The situation represented by the inequality 14.25x > 128 is B. Darmal earns $14.25 per hour at his job. How many hours does he need to work to earn more than $128?

The inequality states that the product of 14.25 and x (representing the number of hours worked) is greater than 128. Solving for x, we can find the number of hours Darmal needs to work to earn more than $128:

14.25x > 128

x > 128 / 14.25

x > 8.96

So, Darmal needs to work more than 8.96 hours to earn more than $128.

Answer: The amount of alcohol the woman consumed can be calculated as follows:

Two glasses of wine * 22 grams of alcohol per glass = 44 grams of alcohol

To convert this amount to milliliters, we need to know the concentration of the alcohol, which is typically around 12% for wine. So, 44 grams of alcohol is equivalent to 44 grams / 0.12 g/mL = 367 mL.

Next, we can calculate the woman's blood alcohol content (BAC) using the following formula:

BAC = (Alcohol consumed in mL) / (Blood volume in mL) * 100%

The blood volume for a 103-pound woman with approximately 6 liters of blood can be estimated as follows:

6 liters * 1000 mL/liter = 6000 mL

So, the BAC can be calculated as follows:

BAC = (367 mL) / (6000 mL) * 100% = 0.0612 * 100% = 6.12%

Therefore, the woman's blood alcohol content would be 6.12% if all the alcohol were immediately absorbed into her bloodstream.
