The restrictions for this equation are that y must be greater than or equal to 0, since the square root of a negative number is not a real number. So, the restrictions for this equation are y ≥ 0.

To solve the equation √y + 6 = 4, we first need to isolate the square root on one side of the equation. We can do this by subtracting 6 from both sides of the equation:
√y = 4 - 6
√y = -2

Now, we need to square both sides of the equation to get rid of the square root:
y = (-2)^2
y = 4

So, the solution to the equation is y = 4. However, we need to verify this solution by plugging it back into the original equation:
√(4) + 6 = 4
2 + 6 = 4
8 = 4

This is not true, so there are no solutions to the equation.

Answer:

(2, 1) is the point where the two lines intersect.

To prove it I'll use substitution

The equations are:

y = 2x - 3 and y = -3x + 7

I'll plug in 2x - 3 for y in y = -3x + 7 so...

2x - 3 = -3x + 7

Simplify:

5x = 10

x = 2

Now I'll plug 2 for x in y = 2x - 3

y = 2(2) - 3

y = 4 - 3

y = 1

So the ordered pair/solution is (2, 1)

The undefined numbers are p = 0, p = 2, q = 0, and q = -2 for the given expression.

In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.

First, let's simplify the expression:

(4p - 8)/(p³ - 2p²) - (q + 2)/(q³ + 2q²) × (p/2q - p)

= 4(p - 2)/(p²(p - 2)) - (q + 2)/(q²(q + 2)) × p(1/2 - q)

= 4/p - 4/p² - p/2q² + p²/2q

= (8q² - 8pq - p³ + 2p²q)/(2pq²(p - 2))

Now, let's find the undefined numbers, which are the values of p and q that make the denominators equal to zero.

For the first fraction, p³ - 2p² = p²(p - 2) = 0 when p = 0 or p = 2.

For the second fraction, q³ + 2q² = q²(q + 2) = 0 when q = 0 or q = -2.

Therefore, the undefined numbers are p = 0, p = 2, q = 0, and q = -2.

If you have a rectangle with a length of 5 and a width of 3, the area would be 5 * 3 = 15.

To factorise a quadratic equation, you need to find two numbers that multiply to give the constant term and add to give the coefficient of the x term.

For example, if you have the equation x^2 + 5x + 6 = 0, the two numbers you need to find are 2 and 3, because 2 * 3 = 6 and 2 + 3 = 5. So the equation can be factorised as (x + 2)(x + 3) = 0.

The altitudes of a triangle are the angle bisectors of the orthic triangle is true because the orthic triangle is formed by the feet of the altitudes of the original triangle. The circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle is true because circumcircle of a triangle passes through all three vertices.

To prove the first statement, we can use the fact that the altitudes of a triangle are perpendicular to the sides and intersect at the orthocenter. The orthic triangle is formed by the feet of the altitudes of the original triangle.
1. Let ABC be the original triangle and D, E, F be the feet of the altitudes from A, B, and C, respectively.
2. Since AD is an altitude, ∠ADB and ∠ADC are right angles.
3. Similarly, ∠BEC and ∠BFC are right angles.
4. Therefore, ∠BDC and ∠EDF are supplementary angles, meaning they add up to 180 degrees.
5. Since ∠BDC and ∠EDF are supplementary and they share a common side, they are also the angle bisectors of the orthic triangle DEF.
6. The same logic can be applied to the other two altitudes to show that they are also angle bisectors of the orthic triangle.

To prove the second statement, we can use the fact that the circumcircle of a triangle passes through all three vertices.
1. Let ABC be the original triangle and D, E, F be the feet of the altitudes from A, B, and C, respectively.
2. Let O be the circumcenter of the original triangle ABC.
3. Since the circumcircle passes through all three vertices, OD, OE, and OF are all radii of the circle.
4. Since all radii of a circle are equal, OD = OE = OF.
5. Therefore, the circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle, as they are all equidistant from the center of the circle.

In response to the supplied query, we may state that Hence, Brenda's Pythagorean theorem home is around 7.2 kilometers away from the school.

The fundamental Euclidean geometry relationship between the three sides of a right triangle is the Pythagorean Theorem, sometimes referred to as the Pythagorean Theorem. This rule states that the areas of squares with the other two sides added together equal the area of the square with the hypotenuse side. According to the Pythagorean Theorem, the square that spans the hypotenuse (the side that is opposite the right angle) of a right triangle equals the sum of the squares that span its sides. It may also be expressed using the standard algebraic notation, a2 + b2 = c2.

Points A, B, and C can be used to create a right triangle in this situation. The hypotenuse of the line segment between points A and C is its length, while the other two sides are the lengths of the segments connecting A and B and B and C.

We'll refer to the separation between positions A and C as "x". Next, we have:

Answer: (x - 4, y - 5)

Step-by-step explanation: (x, y) --> (x - 4, y - 5)

All four statements are logically equivalent.

The statements (a), (b), (c), and (d) are all logically equivalent because they all describe the same concept: that the matrix A has a solution for every possible vector b.

Let's start with statement (a): For each b∈Rm, the matrix equation Ax=b has a solution. This means that for any vector b in Rm, there exists a vector x in Rn such that Ax=b.

Now, let's look at statement (b): Each b∈Rm is a linear combination of the columns in A. This means that for any vector b in Rm, we can write b as a linear combination of the columns of A, which is equivalent to saying that Ax=b has a solution.

Statement (c) says that the columns of A span Rm. This means that the columns of A can be combined in a linear combination to produce any vector in Rm, which is equivalent to saying that Ax=b has a solution for any vector b in Rm.

Finally, statement (d) says that the reduced echelon form of A has a pivot in every row. This means that the matrix A is of full rank and that there are no free variables in the equation Ax=b. This implies that there is a unique solution for every vector b in Rm, which is equivalent to saying that Ax=b has a solution for any vector b in Rm.

Therefore, all four statements are logically equivalent because they all describe the same concept: that the matrix A has a solution for every possible vector b.

The solution to this question is to understand that all four statements are logically equivalent because they all describe the same concept: that the matrix A has a solution for every possible vector b.

Below, you will learn how to solve the problem.

(a) To find the linear relationship y = mx + b between x = year and y = profit, we first need to find the slope (m) and the y-intercept (b).

The slope (m) is the change in y (profit) divided by the change in x (year):
m = (17 - 5)/(6 - 2)

m = 12/4

m = 3

Next, we can use one of the data points (2, 5) and the slope (3) to find the y-intercept (b):
5 = 3(2) + b
b = 5 - 6

b = -1

So the linear relationship between x = year and y = profit is:

y = 3x - 1

(b) To find the company's profit at the end of 3 years, we can plug in x = 3 into the equation:
y = 3(3) - 1

y = 8

So the company's profit at the end of 3 years is $8 million.

(c) To predict the company's profit at the end of 8 years, we can plug in x = 8 into the equation:

y = 3(8) - 1 = 23

So the company's profit at the end of 8 years is predicted to be $23 million.

The simple interest rate for this loan is 12.4%.

To find the simple interest rate, we can use the formula for simple interest, which is:
Simple Interest = Principal x Rate x Time

In this case, we are given the simple interest (\$496), the principal (\$12,000), and the time (4 months). We can plug these values into the formula and solve for the rate.
\$496 = \$12,000 x Rate x (4/12)

Simplifying the equation, we get:
\$496 = \$4,000 x Rate

Dividing both sides by \$4,000, we get:
Rate = 0.124

To convert this to a percentage and round to one decimal place, we multiply by 100 and round:
Rate = 0.124 x 100 = 12.4%

To solve this problem, we can use a system of linear equations. Let x be the cost of each shirt, y be the cost of each pair of slacks, and z be the cost of each sports coat. Then we can write the following equations based on the information given in the problem:

3x + 2y = 18.45 (equation 1)

7x + 2y + z = 35.40 (equation 2)

4x + 2z = 23.94 (equation 3)

Now we can use the elimination method to solve for the variables. First, we can subtract equation 1 from equation 2 to eliminate the y variable:

4x + z = 16.95 (equation 4)

Next, we can multiply equation 1 by -2 and add it to equation 3 to eliminate the y variable:

-6x - 4y + 4x + 2z = -36.9 + 23.94

-2x + 2z = -12.96 (equation 5)

Now we can subtract equation 4 from equation 5 to eliminate the x variable:

2z - z = -12.96 - 16.95

z = -29.91

This value for z does not make sense, so there must be a mistake in the calculations or the original problem. Therefore, it is not possible to determine how much Jim was charged for each shirt, each pair of slacks, and each sports coat with the given information.

Step-by-step explanation:

Part A

The equation for revenue gained for x tickets sold by Alpacas team

is y = 7.5x

This indicates the slope is 7.5 which means for every ticket sold the revenue increases by $7.50

Or in other words, cost of each ticket = $7.50

The revenue - ticket relationship for the Stingrays is given in the form of a graph with a linear equation

The slope of the graph can be found by rise/run where rise

= difference in y values for 2 points on the graph and run

= difference in the corresponding x values

Let's take points (0, 0) and (100, 1500) to find the slope
rise = (1500 - 0)/(10-0) = 1500/10 = 150

run = 10 - 0 = 10

Slope = 150/10 = 15

Equation is y = 15x

So for every ticket sold, the revenue increases by $15

Or in other words, cost of each ticket = $15

Therefore each Stingrays ticket costs 15/7.5 = 2 times each Alpacas ticket

Correct Answer:
Option C

---------------------------------------------------------------------------------------------------------

Part B

For the Geckos swim team we can see that as the number of tickets increases from 6 to 18(difference of 18- 6 = 12), the revenue increases by 180 - 60 = $120

Cost for ticket between 6 and 18 tickets = $120/12 = $10

When tickets sold increases from 18 to 54 (difference of 54 - 18= 36), the revenue increases by $540 - $180 = $360

Therefore the price for each ticket within this range = $360/36 = $10

So the price per ticket is the same regardless of the number of tickets sold

Therefore Gecko's revenue can be modeled as y = 10x

Alpacas charge $7.50 per ticket and Gecko's charge $10 per ticket
So the difference between a Gecko's ticket and an Alpacas ticket

= $10 - $7.50

= $2.50 more than Alpacas

or, alternatively

Alpacas charge $2.50 less than Gecko per ticket

Slope-intercept form is a common way to express a linear function.

Solving For Slope-Intercept

In the question, we are given standard form. In order to find slope-intercept, we need to solve for y. This means we need to use the properties of equality to isolate y from the other values.

First, add 6x to both sides.

Then, divide both sides by 6.

This gives us the final slope-intercept form of the given equation.

Interpreting the Equation

Slope-intercept form is written in the format of y = mx + b. In this equation, m is the slope and b is the y-intercept. Our equation is [tex]y=\frac{6}{5} x+1[/tex]. So, 6/5 is the slope. This means that the rate of change of the graph is 6 units per 5 units. Additionally, the y-intercept is 1. So, the graph crosses the y-axis at y = 1.

The value of (x-y)² is m^2-4n.

To find the value of (x-y)², we can use the formula for the difference of squares:
(x-y)² = (x+y)² - 4xy

We are given that x+y = m and xy = n, so we can substitute these values into the formula:
(x-y)² = m² - 4n
