Answer:

  (c)  (0, 6)

Step-by-step explanation:

Conventionally, an "ordered pair" is a pair of items in parentheses, separated by a comma. The items don't have to be numbers. (0, 6) is an ordered pair.

Curly braces are usually used as delimiters of a set, not an ordered pair.

Three items do not constitute a "pair." Rather, they are a "triple."

Items without any particular indicator of grouping are usually not considered a "pair."

The slope and y-intercept of the linear equation 3x - 4y = 4 will be 3/4 and negative 1, respectively.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

3x - 4y = 4

Convert the equation into slope-intercept form, then we have

3x - 4y = 4

4y = 3x - 4

y = (3/4)x - 1

The slope and y-intercept of the linear equation 3x - 4y = 4 will be 3/4 and negative 1, respectively.

Answer: negative one third

Answer:

-1/3

Explanation:

There's a formula that I'll use to find the slope - it's called the slope formula.

\(\sf{m=\dfrac{y_2-y_1}{x_2-x_1}}\)

Plug in the data:

\(\sf{m=\dfrac{8-4}{-4-8}}\\\\\sf{m=\dfrac{4}{-12}\)

Simplify:

\(\sf{m=-\dfrac{4}{12}}\)

\(\sf{m=-\dfrac{1}{3}}\)

Hence, the slope is negative one-third.

Step-by-step explanation:

The interest Edward earned from the savings account in which he deposited $6,000 for 4 years at a simple interest rate of 3% was $720.

Simple interest is the interest system that calculates interest only on the principal.

Unlike compound interest, simple interest does not compute interest on the accumulated interest.

Savings account deposit = $6,000

Savings period = 4 years

Simple interest rate = 3%

Simple interest = Principal x Rate x Time

= $6,000 x 3% x 4

= $720

Thus, Edward earned $720 in interest from the savings.

The solution is the point (0, 1/6) y = 1/6

Given the equation y = (-3/4)x + 1/6, which represents a linear equation, there is no "system" of equations involved since there is only one equation.

In this case, the equation is in slope-intercept form (y = mx + b),

where m represents the slope (-3/4) and b represents the y-intercept (1/6).

The slope-intercept form allows us to determine various properties of the equation.

Since there is only one equation, the solution to this equation is a single point on the Cartesian plane.

Each pair of x and y values that satisfy the equation represents a solution.

For example, if we choose x = 0, we can substitute it into the equation to find the corresponding y value:

y = (-3/4)(0) + 1/6

y = 1/6

Therefore, the solution is the point (0, 1/6).

In summary, the given equation has a unique solution, represented by a single point on the Cartesian plane.

Any value of x plugged into the equation will yield a corresponding y value, resulting in a unique point that satisfies the equation.

A quadrilateral is a shape with four sides

The indicated measures are A = 56, B = 128, C = 100 and D = 76

The angles in a quadrilateral add up to 360 degrees.

So, we have:

4n + 5n + 6 + 9n + 2 + 8n - 12 = 360

Collect like terms

4n + 5n + 9n + 8n = 360 - 6 - 2 + 12

Evaluate the like terms

26n = 364

Divide through by 26

n = 14

From the figure, we have:

A = 4n

B = 9n + 2

C = 8n - 12

D = 5n + 6

So, we have:

A = 4 * 14 = 56

B = 9*14 + 2 = 128

C = 8*14 - 12 = 100

D = 5*14 + 6 = 76

Hence, the indicated measures are

A = 56, B = 128, C = 100 and D = 76

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The given function is:

f(x) = -(x + 3) - 1

To find the interval over which the function is decreasing, we need to find the values of x where the function's derivative is negative.

The derivative of the function is:

f'(x) = -1

The derivative is a constant, which means the function has a constant slope of -1. Since the slope is negative, the function is decreasing over its entire domain.

Therefore, the interval over which the graph of f(x) = -(x + 3) - 1 is decreasing is (-∞, +∞).

Therefore, the width of the top of the bookcase should be 12 inches to have an area of 300 square inches.

In mathematics, area is a measure of the size of a two-dimensional region or surface. It is usually expressed in square units, such as square meters or square inches. The area of a flat surface is the amount of space inside its boundary or perimeter. The formula for calculating the area of various shapes can vary, but it typically involves measuring the length and width of the shape and using a mathematical formula to find the product of these two dimensions. For example, the area of a rectangle can be found by multiplying its length by its width, while the area of a circle can be found by multiplying pi (approximately 3.14) by the square of its radius.

Here,

Let's assume that the top of the bookcase is a rectangle with length (L) and width (b), so its area is given by the formula:

A = L * b

We are told that Bria's soap carving collection needs an area of 300 square inches. Therefore, we can write:

300 = L * b

Solving for b, we can divide both sides by L:

b = 300 / L

We don't know the value of L, but we can assume that it's some value that Bria has already determined. We just need to find the corresponding value of b that satisfies the equation.

For example, if Bria decides that the length of the top of the bookcase should be 20 inches, we can substitute L = 20 into the equation above:

b = 300 / 20 = 15 inches

So in this case, the width of the top of the bookcase should be 15 inches in order to have an area of 300 square inches.

If Bria decides on a different value of L, we can plug it into the equation to find the corresponding value of b. For instance, if she decides that L should be 25 inches:

b = 300 / 25 = 12 inches

Step-by-step explanation:

The solution to the polynomial equation 8x⁴ - 32x² = 0 by factoring are x = 0 or x = -2 or x = 2

To solve the equation 8x⁴ - 32x² = 0 by factoring, we can factor out the greatest common factor of the terms:

8x²(x² - 4) = 0

Now we can use the difference of squares identity to factor the quadratic expression:

8x²(x + 2)(x - 2) = 0

Using the zero product property, we know that the product of two factors is zero if and only if at least one of the factors is zero.

Therefore, we can set each factor equal to zero and solve for x:

8x² = 0 or x + 2 = 0 or x - 2 = 0

Solving for x, we get:

x = 0 or x = -2 or x = 2

So the solution set for the equation is {0, -2, 2}.

To check the solution, we can substitute each value into the original equation and verify that it equals zero.
