What are two ways to show the mixed number: 4 and two-tenths?

The standard form of the linear function in this problem is given as follows:

-4x + 5y = -25.

The linear function for this problem is defined in point-slope form as follows:

y + 1 = 4/5(x - 5).

To convert to standard form, we leave the coefficients of x and y on the left side and the constant on the right side, hence:

y + 1 = 4x/5 - 4.

-4x/5 + y = -5.

Multiplying everything by 5, we have that:

-4x + 5y = -25.

Step-by-step explanation:

The vertices of the polygon in the graph have co-ordinates as J(6,3) K(2,3) L(2,-3) M(6,-3)

In geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain.

Given here: A polygon JKLM

From the graph we can observe the co-ordinates as J(6,3) K(2,3) L(2,-3) M(6,-3)

Hence, the vertices of the polygon in the graph have co-ordinates as J(6,3) K(2,3) L(2,-3) M(6,-3)

The t critical value for a two-sided confidence interval in each of the following situations:

a. Confidence level = 95%, df = 10, t critical value = 1.812

b. Confidence level = 95%, df = 15, t critical value = 1.753

c. Confidence level = 99%, df = 15, t critical value = 2.602

d. Confidence level = 99%, n = 5, t critical value = 3.365

e. Confidence level = 98%, df = 24, t critical value = 2.306

f. Confidence level = 99%, n = 38, t critical value = 2.821

The t-critical value is a value that is used to determine the margin of error in a two-sided t-test with a given level of confidence and degrees of freedom. The t-critical value can be looked up in a t-table, or calculated using a t-distribution calculator.

It is important to note that for a small sample size (n<30) t-distribution is used instead of the normal distribution, in that case, the degrees of freedom is n-1 and the t-critical value is different than the one calculated with degrees of freedom.

All the angles from the polygon path made by the students are;

∠1 = 96°

∠2 = 90°

∠3 = 162°

∠4 = 132°

∠5 = 60°

The images of the polygon are missing and so i have attached them. From the attached image, we can see we have;

Triangle (3-sided polygon)

Square (4-sided polygon)

Pentagon (5-sided polygon)

Hexagon (6 sided polygon)

Now, we know that formula for external angle of a polygon with n sides is 360/n.

Thus, for the 6-sided polygon, the ∠5 = 360/6

∠5 = 60°

Since ∠4 is shared by the pentagon and hexagon, then;

∠4 = (360/5) + 60

∠4 = 72° + 60°

∠4 = 132°

Since ∠3 is shared by the square and pentagon, then;

∠3 = 90 + 72

∠3 = 162°

∠2 = 90° because external angles of a square = 360/4 = 90°

A mathematical expression made up of coefficients and uncertainty that only makes use of additions, subtractions, multiplications, and positive integer powers of variables is known as a polynomial. The formula x2 4x + 7 denotes a single indeterminate x polynomial. An expression in mathematics known as a polynomial is made up of variables (also known as indeterminates) and coefficients that may be added, subtracted, multiplied, and raised to negative integer powers of non-variables. An algebraic statement with variables and coefficients is called a polynomial. An expression can only contain the operations addition, subtraction, multiplication, and non-negative integer exponents.

The four methods to solve quadratic equations are factorising, quadratic formula, graphing and completing the square.

Factorising is nothing but the method of equating the given equation to zero.

Quadratic formula method is by placing the coefficients of the given quadratic equation into the formula and obtaining the solutions.

Completing the square method is when a quadratic equation has a square term. We would once more have a linear equation if we could place two square terms on either side of the quality sign.

We can find the solution of a quadratic equation using a graph. Rearrange the equation so that one side corresponds to the graphed function. Plot this function and write y = the other side of the equation. To obtain the answers, draw vertical lines from the intersection spots down to the x-axis.

Rachel has 0.41 quarters that can be obtained using the equation Q + D + N = T.

We can start by using the following equation to find the number of quarters Rachel has: Q + D + N = T

Where Q is the number of quarters, D is the number of dimes, N is the number of nickels, and T is the total amount of money in dollars. We know that T is $4.65, and we know that Rachel has twice as many nickels as quarters, and three more quarters than dimes.

Let's assume that Rachel has x number of quarters

So we can write the above equation as:

x + (x+3) + 2x = 4.65

4x+3 = 4.65

4x = 1.65

x = 0.4125

Rachel has 0.4125 quarters, Which is not possible as it is a decimal. So we need to round it off to the nearest whole number.

Rachel has 0.4125 quarters which is equivalent to o.41 quarters.

The determinants for solving the linear system is given as follows:

The system of equations for this problem is defined as follows:

The matrix A is composed by the coefficients of x and y, hence:

A = [5 3]

  = [-8 -3]

The determinant of a 2 x 2 matrix is the multiplication of the principal diagonal subtracted by the multiplication of the secondary diagonal, hence:

|A| = 5 x (-3) - 3 x (-8)

|A| = -15 + 24

|A| = 9.

For the matrix Ax, the coefficients of x are replaced by the results of the equalities, hence:

Ax = [17 3]

    = [9 - 3]

|Ax| = 17 x (-3) - 3 x 9

|Ax| = -51 - 27

|Ax| = -78.

For the matrix Ay, the coefficients of y are replaced by the results of the equalities, hence:
