The answer is "no," the ordered pair (4, 28) is not a solution of the equation.

A solution of an equation is a value or set of values that makes the equation a true statement when substituted for the variable(s) in the equation.

To determine if the ordered pair (4, 28) is a solution of the equation 7 = y - 5x, we need to substitute the values x = 4 and y = 28 into the equation and check if it is a true statement:

7 = y - 5x

7 = 28 - 5(4) // Substitute x = 4 and y = 28

7 = 28 - 20

7 = 8

The statement 7 = 8 is not true, which means that the ordered pair (4, 28) is not a solution of the equation 7 = y - 5x. Therefore, the answer is "no," the ordered pair (4, 28) is not a solution of the equation.

The e values that satisfy the inequality 3e ≤ 6, are e = 1 and e = 2.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

To determine which values of e satisfy the inequality 3e ≤ 6, we can divide both sides by 3 -

3e/3 ≤ 6/3

e ≤ 2

Therefore, any value of e that is less than or equal to 2 will satisfy the inequality.

Out of the given choices, e = 1 and e = 2 satisfy the inequality, but e = 3 does not, because 3 is greater than 2.

The reference angle for A = -300° is given by R = 60°

Every angle is measured from the positive part of the x-axis to its terminal line (the line that determines the end of the angle) traveling counterclockwise. For angles in the first quadrant, i.e., angles less than or equal to 90 degrees, the reference angle is equal to the original angle.

The reference angle is always positive

0° to 90°: reference angle = angle

90° to 180°: reference angle = 180° - angle

180° to 270°: reference angle = angle - 180°

270° to 360°: reference angle = 360° - angle

Given data ,

Let the reference angle be represented as R

Now , let the given angle be A

A = -300°

And , for 270° to 360°: reference angle = 360° - angle

when the angle is negative and less than -270°

The reference angle is given by adding 360° to it and the angle lies in the first quadrant

So , the reference angle R = A + 360°

R = -300 + 360

Answer:

the future value or total amount due at the end of 8 months is $9,330.00

Step-by-step explanation:

To find the future value of a loan that is borrowed at a simple interest rate, we use the formula:

A = P(1 + rt)

where A is the future value or total amount due, P is the principal or initial amount borrowed, r is the simple interest rate as a decimal, and t is the time period in years.

In this case, the principal is $9000, the simple interest rate is 5.5% or 0.055 as a decimal, and the time period is 8 months or 8/12 = 2/3 years.

Substituting these values into the formula, we get:

A = 9000(1 + 0.055 × 2/3)

= 9000(1.0375)

= $9,330.00

Therefore, the future value or total amount due at the end of 8 months is $9,330.00

we know that a year has 12 months, so 8 months is really 8/12 of a year.

binary operation has at most one identity element.

A binary operation is a mathematical operation that takes two elements from a set and combines them to produce a third element in the same set. In other words, it is an operation that involves two operands, which can be numbers, variables, or other mathematical objects.

Let's suppose that a binary operation "⋆" has two identity elements "e" and "f", where "e" and "f" are distinct. This means that for any element "a" in the set on which the binary operation is defined, we have:

a ⋆ e = a and f ⋆ a = a (since "e" and "f" are identity elements)

Now, let's consider what happens when we apply the binary operation "⋆" to "e" and "f":

e ⋆ f = f (since "e" is an identity element)

e ⋆ f = e (since "f" is an identity element)

This means that "f = e", which contradicts our assumption that "e" and "f" are distinct. Therefore, it is not possible for a binary operation to have two distinct identity elements.

Hence, we can conclude that a binary operation has at most one identity element.

Next, we can simplify further by combining like terms:

28m - 26m = -39 + 7

2m = -32

Finally, we can solve for m by dividing both sides of the equation by 2:

m = -16

Therefore, the solution to the equation -7(1-4m)=13(2m-3) is m = -16.

Amount financed = Total price - Down payment

Amount financed = $34,000 - $6,800 = $27,200

To calculate the monthly payment, we can use the following formula:

Monthly payment = (Pr(1+r)^n) / ((1+r)^n - 1)

where:

P = amount financed

r = monthly interest rate

n = number of months

First, we need to calculate the monthly interest rate:

Monthly interest rate = APR / 12

Monthly interest rate = 4.4% / 12 = 0.0036667

Now, we can calculate the monthly payment:

Monthly payment = ($27,200 * 0.0036667 * (1+0.0036667)^60) / ((1+0.0036667)^60 - 1)

Monthly payment = $501.47

The total cost of the car is the sum of the down payment and the total of all the monthly payments over 60 months:

Total cost = Down payment + Monthly payment * 60

Total cost = $6,800 + $501.47 * 60

Total cost = $37,688.20

Therefore, the total cost of Lynette's car is $37,688.20.

The solutions to the equation x²= -8x - 7 are x = -1 or x = -7.

A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .

To complete the square for this equation x^2 = -8x - 7

Adding the square of half the coefficient of x (which is (-8)/2 = -4) to both sides of the equation:

x² + 8x + (-4)²= -7 + (-4)^2

This gives us:

x² + 8x + 16 = 9

Now we can write the left-hand side as a perfect square:

(x + 4)² = 9

Taking the square root of both sides gives us:

x + 4 = ±3

Solving for x, we get:

x = -4 ± 3

Therefore, the solutions to the equation x²= -8x - 7 are: x = -1 or x = -7.

1) 18 - a/16 = 17

18 - a = 16 * 17

18 - a = 272

a = 18 - 272

a = -254

2) 15 - n/-10 = -21

15 - n = (-21) * (-10)

15 - n = 210

n = 15 - 210

n = -195

3) 12 + y/-20 = 18

12 + y = 18 * (-20)

y = -372

4) c + 17/-26 = -5

c + 17 = (-5) (-26)

c = 113
