Horizontal lines have a slope of zero, since the "rise" is; zero.

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Since we know that Vertical lines have an undefined slope, since the "offset" is zero, and division by zero is not allowed.

If the slope has a value of zero, the line is horizontal, neither increases nor decreases.

Therefore,

Horizontal lines always have an equation of the form; y = a

Vertical lines always have an equation of the form; x = b

The requried solution of the system of equations is (-1, -2). Option C is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Two intersecting lines will have exactly one solution (i.e., a unique point of intersection) if and only if they are not parallel.

In other words, if the slopes of the two lines are different, they will intersect at a single point. This is because the slopes of the lines determine how steep they are, and if they are not the same, they will eventually cross at a single point. So from the graph, both lines intersect at (-1, -2) implying that The solution is (-1, -2).

The equation of the cubic function is 2( x-4) (x-3) x+3)

A cubic function is a polynomial function of degree 3 and is of the form f(x) = ax3 + bx2 + cx + d, where a, b, c, and d are real numbers and a ≠ 0.

The equation of a cubic function is given as;

x³-(a+b+c) x² + ( ab+bc+ca) x + abc

where a,b,c are the root of the cubic function

a = 4, b = 3 and c= -3

a+b+c = 4+3-3 = 4

ab = 4×3 = 12

bc = -3×3 = -9

ca = -3×4 = -12

ab+bc+ca = 12-9-12 = -9

abc = 4×3×-3 = -36

therefore;

x³-( 4)x² + ( -9)x -36

x³-4x²-9x -36

therefore y = a( x-4) (x-3) x+3)

at point (2,20)

substitute x by2 and y by 20

20 = a( -2) (-1) (5)

20 = a10

a = 20/10

a= 2

The missing value in the expression A = -2(x-9)² + ? is 162, which represents the maximum area of the storage bin.

A perfect Square is defined as an integer multiplied by itself to generate a perfect square, which is a positive integer. Perfect squares are just numbers that are the products of integers multiplied by themselves.

To complete the perfect square, we need to factor out the coefficient of the squared term (-2) from the expression:

A = -2x² + 36x

A = -2(x² - 18x)

Next, we need to add and subtract the square of half the coefficient of the x-term (-18/2 = -9) inside the parentheses:

A = -2(x² - 18x + (-9)² - (-9)²)

Simplifying the expression inside the parentheses, we get:

A = -2[(x - 9)² - 81]

Distributing the -2, we get:

A = -2(x - 9)² + 162

Therefore, the missing value in the expression is 162.

The weighted average price index is 171, which means that the average price of the components in Year 2 was 171% of their average price in Year 1.

To compute the weighted average of relatives, we need to find the weighted average of the ratio of the prices of each component in Year 2 to Year 1. Let's call this ratio the "relative price".

Relative price for component A = Po Year 2 / Po Year 1 = 6.00 / 3.00 = 2.00

Relative price for component B = Pn Year 2 / Pn Year 1 = 8.50 / 6.80 = 1.25

Relative price for component C = Pn Year 2 / Po Year 1 = 17.68 / 20.80 = 0.85

Next, we'll find the weighted average of the relatives by summing the product of each relative price and its corresponding standard weight, and dividing by the sum of the standard weights.

Weighted average of relatives = (2.00 * 16 + 1.25 * 6 + 0.85 * 2) / (16 + 6 + 2)

= (32 + 7.5 + 1.7) / 24

= 41.2 / 24

= 1.71

The weighted average of relatives is 1.71, which means that the average price of the components increased by 71% from Year 1 to Year 2.

To compute the weighted average price index, we'll use the weighted average of relatives as a reference point and multiply it by 100.

Weighted average price index = Weighted average of relatives * 100

= 1.71 * 100

= 171

Therefore the weighted average price index is 171, which means that the average price of the components in Year 2 was 171% of their average price in Year 1.

If the shortest leg of the small triangle is 4 in and the hypotenuse is 12 in and the shortest leg of the large triangle 8 in, then the length of the hypotenuse of the large triangle is 24 inches.

We know that two triangles are proportional if their corresponding sides are in proportion to each other. That is, the ratio of the lengths of the corresponding sides is the same for both triangles.

Let's denote the length of the hypotenuse of the large triangle by "h". We can set up a proportion using the given information:

shortest leg of small triangle / hypotenuse of small triangle = shortest leg of large triangle / hypotenuse of large triangle

Plugging in the values we get:

4/12 = 8/h

Simplifying the equation we get:

h = (12*8)/4 = 24

To explain the solution, we used the fact that similar triangles have proportional sides. We then used the given information about the lengths of the sides of the small and large triangles to set up a proportion and solve for the unknown length of the hypotenuse of the large triangle.

The key to this problem was recognizing the relationship between similar triangles and using that relationship to set up and solve a proportion.

For given linear inequalities in step 3 and 7 properties shown are Commutative property and addition property of inequality.

What exactly is a linear inequality?

In mathematics, inequality denotes a mathematical statement with no equal sides. An inequality happens in mathematics when a connection results in a non-equal comparison of two expressions or two numbers. Any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠), replace the equal sign "=" in the sentence. In mathematics, inequalities are classified into three types: polynomial inequalities, rational inequalities, and absolute value inequalities.

The characters "< and >" denote severe inequalities, whereas ‘≤’ and ‘≥’  denote slack inequalities. A linear inequality looks to be a linear equation, however the formula is different.

Now,

As stated in Commutative property the order in addition does not matter and in addition property the value added on both sides does not affect the result.

In step 3 we can write this as 5x-x-5<11x+x-21

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.

The derivative of the composite function f(x) = (3 · x · cos x + √x) / [5 · x² · (sin x + 1)] is equal to f'(x) = [[3 · cos x - 3 · x · sin x + (1 / 2√x)] · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · [5 · x · (sin x + 1) + 5 · x² · cos x]] / [5 · x² · (sin x + 1)]².

In this problem we must determine the derivative of the composite function f(x) = (3 · x · cos x + √x) / [5 · x² · (sin x + 1)]. This can be done by using the following derivative rules:

Derivative of the addition of two functions

d [f(x) + g(x)] / dx = df(x) / dx + dg(x) / dx

Derivative of the product of two functions

d [f(x) · g(x)] / dx = [df(x) / dx] · g(x) + f(x) · [dg(x) / dx]

Derivative of the division of two functions

d[f(x) / g(x)] / dx = [[df(x) / dx] · g(x) - f(x) · [dg(x) / dx]] / [g(x)]²

Derivative of a function and a constant

d [c · f(x)] / dx = c · df(x) / dx

Derivative of a power function

d [xⁿ] / dx = n · xⁿ⁻¹

Derivative of cosine

d [cos x] / dx = - sin x

Derivative of sine

d [sin x] / dx = cos x

Now we proceed to determine the derivative of the function by derivative rules:

f'(x) = [d [3 · x · cos x + √x] / dx · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · d [5 · x² · (sin x + 1)] / dx] / [5 · x² · (sin x + 1)]²

f'(x) = [[3 · cos x - 3 · x · sin x + (1 / 2√x)] · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · [5 · x · (sin x + 1) + 5 · x² · cos x]] / [5 · x² · (sin x + 1)]²
