The cost of one rose bush is $2 and the cost of one bunch of grass is $17.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Given that, Norachai and Rain each improved their yards by planting rose bushes and grass.

Let the cost of rose bushes be x and the cost of bunches of grass be y.

Norachai spent $209 on 11 rose bushes and 11 bunches of grass.

Now, 11x+11y=209

x+y=19 --------(i)

Rain spent $40 on 3 rose bushes and 2 bunches of grass.

3x+2y=40 --------(ii)

Substitute x=19-y in equation (ii), we get

3(19-y)+2y=40

57-3y+2y=40

57-40=y

y=17

Substitute y=17 in equation (i), we get

x=2

Therefore, the cost of one rose bush is $2 and the cost of one bunch of grass is $17.

Answer: The coordinates of a point in the plane are represented by a pair of values, (x, y), where x is the horizontal position and y is the vertical position.

When a point is reflected across the x-axis, the x-coordinate remains the same, but the sign of the y-coordinate changes. This is because the x-axis acts as a mirror, flipping the point over to the opposite side of the axis.

So, the coordinates of the reflected point would be (x, -y).

In summary, the x-coordinates of a point and its reflection across the x-axis are the same, while the y-coordinates are different (one is positive, and the other is negative).

Step-by-step explanation:

Numbers that summarize a sample of data are called "sample statistics," and numbers that summarize populations are called "population parameters."

A sample statistic is a single value that describes a characteristic of a sample, such as the mean, median, or standard deviation. Sample statistics are used to make inferences about the population from which the sample was drawn.

A population parameter, on the other hand, is a single value that describes a characteristic of an entire population, such as the population mean, population standard deviation, or population proportion. Population parameters are usually not known and must be estimated from a sample.

For example, if you have a sample of 100 students' heights, the mean height of the sample (a sample statistic) can be calculated and used to make inferences about the mean height of the population of all students.

Step-by-step explanation:

You want to know the interest rates that yield $168 on investments of $2200 at one rate and $1000 at a rate 4% higher.

Let r represent the lower interest rate. Then x+0.04 is the higher rate, and the total interest earned is ...

  2200r +1000(r +0.04) = 168

Simplifying the equation, we have ...

  3200r +40 = 168

  3200r = 128 . . . . . . . . subtract 40

  r = 128/3200 = 0.04 = 4% . . . . . divide by the coefficient of r

The minimum number of rotations required for a 3500 km race is 52,800 rotations.

This is calculated by dividing the total distance of the race, 3500 km, by the circumference of the wheel, which is 2πr, where r is the radius of the wheel. The radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm). So, the minimum number of rotations is given by 3500/(23.14r), where r is the minimum radius of the wheel. Substituting in r = 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.

To arrive at this result, we must first calculate the circumference of the wheel, which is given by 2πr, where r is the radius of the wheel. Since the diameter of the wheel must be between 55 cm and 75 cm, the radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm).

We then divide the total distance of the race, 3500 km, by the circumference of the wheel, which is given by 2πr. Substituting in the minimum radius of the wheel, 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.

Given that x, y, z are different and satisfy the equations:

x^3 + x^2 - x = 0

y^3 + y^2 - y = 0

z^3 + z^2 - z = 0

We can multiply the first equation by y, the second by z, and the third by x to obtain:

x^3y + x^2y - xy = 0

y^3z + y^2z - yz = 0

z^3x + z^2x - zx = 0

Adding these three equations together, we get:

x^3y + x^2y - xy + y^3z + y^2z - yz + z^3x + z^2x - zx = 0

Expanding and simplifying, we find that:

x^2y + xy^2 + y^2z + yz^2 + z^2x + zx^2 - xy - yz - zx = 0

Now, we use the fact that x, y, and z are roots of the equations given above to simplify the expression further:

x^2 - x + y^2 - y + z^2 - z = 0

We can also write this as:

(x - 1)(x + 1) + (y - 1)(y + 1) + (z - 1)(z + 1) = 0

This expression can be factorized as:

(x - 1)(x + 1)(y - 1)(y + 1)(z - 1)(z + 1) = 0

Since x, y, and z are all different, we have that:

(x - 1)(x + 1) ≠ 0

(y - 1)(y + 1) ≠ 0

(z - 1)(z + 1) ≠ 0

Therefore, we have:

(x - 1)(x + 1)(y - 1)(y + 1)(z - 1)(z + 1) = (x - 1)(x + 1)(y - 1)(y + 1)(z - 1)(z + 1) = 0

Note that where the figure below contains two semi-circles that are tangent to each Other at point B and ray DE is tangent to both semicircles at points E and F, it is correct to state that ED = 6√2 (Option A).

A semicircle is a one-dimensional point collection that forms half of a circle in mathematics. It is a circular arc with a circumference of 180°. It just has one symmetry line.

Solving the ED, we have:

ΔDEM ~ ΔDFP

This means that MD/PD = EM/FP

MD/(MD + 9) = 3/6
6MD = 3MD + 27 (Collect like terms over the equation)
3MD = 27
MD = 9 (If both sides are divided by 9)

P should stand for the population in a certain year. P = 97*(0.875) is the function to model the population change (year-2021).

P should stand for the population in a certain year. To simulate how the animal population changes over time, we can utilise a function. The 12.5% annual reduction rate will be considered by the function. This can be stated mathematically as P = 97*(0.875), which is how it will appear in the equation (year-2021). In this equation, the number 97 stands in for the population in 2021, and the number 0.875 denotes the 12.5% annual decline rate. The exponent (year 2021) represents the number of years that have passed since 2021, allowing the equation to take the population decline over a number of years into consideration. As a result, the equation can be used to determine the animal species' population at the start of a particular year.

the lunch cost, including tax and tip 67.31$.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, the Patterson family went to eat lunch at a new restaurant. They spent $52.30 on their meal. The restaurant will add a 7 1/4% tax to the cost of the meal.

total cost after the tax = 52.30*(1 + 7 1/4)%

total cost after the tax = 52.30* 7.25/100 + 52.30

total cost after the tax = 3.79 + 52.30

total cost after the tax = 56.09

Since,

Mr Patterson was very happy with the food and service so he gave a 20% tip to the waitress.

Thus,

Total cost after the tip = 56.09(1 +20/100)

Total cost after the tip = 56.09 * 1.2

Total cost after the tip =  67.308

The correct option is the third one. The statement "The [tex]\lim_{x \to \0} f(x)=4[/tex] because both the left hand and the right hand limit is equal to 4" identifies and explains the function of limit.

The limit function in mathematics is a way of finding the value that a function or sequence approaches as the input values approach a certain point. It is used to determine the behavior of a function as the input values approach a certain point or their maximum or minimum values.

Where the above two limits say that when we approach zero from the negative side (the first one) and from the positive side (the second one), we must get the same value.

Remember that the limit is an approximation through near points.

Then, regardless the fact that f(0) = -2, we can see that as x approaches 0 from both sides, the value of the function approaches 4.

Thus, we can conclude that the limit of f(x) when x tends to zero is equal to 4.
