Can someone help me with this math homework please!

The point (x, y) = (7, - 1) lies on the line whose equation is y + 4 = (3 / 5) · (x - 2). (Correct choice: E)

In this problem we find five different points of the form (x, y), each of which has to be checked in the linear equation given in the statement. A point is a solution of the linear equation if and only an equality exists, that is, the reflexive property of equalities is guaranteed by evaluating the expression.

Now we proceed to check the expression for each case:

(x, y) = (1, - 5)

- 5 + 4 = (3 / 5) · (1 - 2)

- 1 = (3 / 5) · (- 1)

- 1 = - 3 / 5     (FALSE)

(x, y) = (- 8, - 12)

- 12 + 4 = (3 / 5) · (- 8 - 2)

- 8 = (3 / 5) · (- 10)

- 8 = - 30 / 5

- 8 = - 6    (FALSE)

(x, y) = (- 3, - 8)

- 8 + 4 = (3 / 5) · (- 3 - 2)

- 4 = (3 / 5) · (- 5)

- 4 = - 3    (FALSE)

(x, y) = (12, 10)

10 + 4 = (3 / 5) · (12 - 2)

14 = (3 / 5) · 10

14 = 30 / 5

14 = 6     (FALSE)

(x, y) = (7, - 1)

- 1 + 4 = (3 / 5) · (7 - 2)

3 = (3 / 5) · (5)

3 = 3    (TRUE)

The point (x, y) = (7, - 1) lies on the line whose equation is y + 4 = (3 / 5) · (x - 2).

True for the last two on the right and false for the first one

The measure of the angle ∠JKL is 230°, the area of the shaded and unshaded region is (230/18) × 5π and (325/9) × π. Then statements 1 and 3 are true and statement 2 is false.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The figure is given.

Radius (r) = 10 units

Then the sum of the angle should be 360 degrees for a circle. Then

130° + ∠JKL = 360°

          ∠JKL = 230°

The area of the shaded region will be

\(\rm Shaded \ area = \dfrac{230}{360}\times \pi 10^2\\\\Shaded \ area = \dfrac{230}{360}\times \pi 100\\\\Shaded \ area = \dfrac{230}{18}\times 5\pi \\\)

Then the area of the unshaded region will be

\(\rm Unshaded \ area = \dfrac{130}{360}\times \pi 10^2\\\\Unshaded \ area = \dfrac{130}{360}\times \pi 100\\\\Unshaded \ area = \dfrac{325}{9}\times \pi \\\)

With regard to the similar triangles,

In ΔACD

BE ∥ CD

In ΔACD and ΔABE

BE ∥ CD

∠ACD =∠ABE           (corresponding angles)

∠ADC = ∠AEB          (corresponding angles)

∠A = ∠A                    (common angle)

ACD ∼ ΔABE

So,  The corresponding sides are in proportion.

Now, find ED

AB/BC = AE/ED
ED = AE (BC/AB)
ED = 26(5/20)
ED = 6.5cm


For BE

AB/AC = BE/CD
BE = CD (AB/AC)
BE = 18 (20/25)
BE  = 14.4cm

Now, find BE

Therefore, the length of ED is 6.5cm and the length of BE is 14.4 cm.

Answer:

$55

Explanation:

If you already have $30 and the bracelet cost $250, you need to save $220 in the next four months because:

$250 - $30 = $220

Then, to know how much do you need to save each month, we need to divide $220 by 4, so:

$220 ÷ 4 = $55

Therefore, you need to save $55 each month to be able to buy the bracelet.

The binomial probability formula is used to calculate the probability of a specific number of successes in a fixed number of independent trials, where each trial can only result in success or failure. It is used to model situations where there are only two possible outcomes for each trial, and where the trials are independent and identically distributed.

The formula for binomial probability is:

\(P(x) = (n choose x) * p^x * (1 - p)^{n-x}\\\)

where P(x) is the probability of x successes in n trials, p is the probability of success on each trial, (n choose x) is the binomial coefficient which gives the number of ways to choose x successes from n trials, and (1 - p) is the probability of failure on each trial.

The binomial probability formula can be used in a variety of applications, such as:

To find the percentage, we can use the following formula:

Percentage = (Part / Whole) * 100

So, $131,701.32 is approximately 16.67% of $790,207.91.

In this case, the part is $131,701.32 and the whole is $790,207.91.

Percentage = ($131,701.32 / $790,207.91) * 100

Calculating the value:

Percentage ≈ 0.1667 * 100

Percentage ≈ 16.67%

Therefore, $131,701.32 is approximately 16.67% of $790,207.91.

Alternatively, we can calculate the percentage by dividing the part by the whole and multiplying by 100:

Percentage = ($131,701.32 / $790,207.91) * 100 ≈ 0.1667 * 100 ≈ 16.67%

So, $131,701.32 is approximately 16.67% of $790,207.91.

Step-by-step explanation:

The ratios of their perimeters and the ratios of their areas are 1) 3:1 and 9:1 and 2) 7:4 and 49:16.

Given the scale factor of two similar polygons, we need to find the ratio of their perimeters and the ratios of their areas,

To find the ratio of the perimeters of two similar polygons, we can simply write the scale factor as it is because the ratio of the perimeter is equal to the ration of the corresponding lengths.

1) So, perimeter = 3:1

The ratio of areas between two similar polygons is equal to the square of the scale factor.

Since the scale factor is 3:1, the ratio of their areas is:

(Ratio of areas) = (Scale factor)² = 9/1 = 9:1

Similarly,

2) Perimeter = 7:4

Area = 49/16

Hence the ratios of their perimeters and the ratios of their areas are 1) 3:1 and 9:1 and 2) 7:4 and 49:16.

Answer and Step-by-step explanation:

To solve an inequality, you must solve for the variable. Let's look at an example:

4x + 2 > 10

We solve for x by subtracting 2 from both sides, then dividing 4 on both sides.

(Solve as if you were solving a regular equation)

4x > 8

x > 2

We get x > 2 as our inequality.

To plug in 3 values, simply plug in any number that is greater than 2. That would be the solution to the inequality.

If when solving the inequality and you have to divide by a negative, the sign will change. Ex:

-5x > 25

x < -5

To show that the sign should switch, let's solve it this way.

-5x > 25

0 > 25 + 5x       Add the 5x to both sides.

-25 > 5x            Subtract the 25 from both sides

-5 > x                Divide by 5 from both sides.

As we can see, the inequalities turn out to be the same, which is why you flip the sign when you divide.

if a • b = 0, then a = 0, b = 0, or both a = 0 and b = 0 it is called the Zero Product Property.

The property given is known as the Zero Product Property. It states that if the product of two numbers, a • b, equals zero, then either a is zero, b is zero, or both a and b are zero. In other words, if the product of any two numbers is zero, at least one of the numbers must be zero.

This property is a fundamental concept in algebra and plays a crucial role in solving equations and understanding the behavior of real numbers. It stems from the fact that zero is the additive identity, meaning that any number added to zero remains unchanged. When two non-zero numbers are multiplied together, their product will not be zero. Therefore, if the product is zero, it implies that one or both of the numbers must be zero.

The Zero Product Property is widely used in various algebraic manipulations, such as factoring, solving equations, and determining the roots of polynomials. It provides a key principle for identifying critical values and potential solutions in mathematical expressions and equations.

Step-by-step explanation:

The dilated triangle is names ▲D'E'F' ,

Vertex D' → ( -8, 1)

Vertex E' → (4, 10)

Vertex F' → (7, 1)

What is dilation ?

Reducing the object's size by dilation is a change. The items are enlarged or shrunk through dilation. An image that retains the original shape is created by this alteration. The size of the form does differ, though. A dilatation should either enlarge or decrease the initial form. By using the phrase "scaling factor," this transition is described.

Enlargement is the name given to a dilatation that results in a larger image.

Reduction is what happens when a dilatation results in a smaller picture.

According to question

Since the center of dilation is not at the origin, we can use the following formula in order to find the coordinates of the vertices of the triangle D'E'F':

\(D_{(O,k)}(x,y) = (k(x-a) +a, k(y-b) +b)\)

Where "O" is the center of dilation at (a,b) and "k" is the scale factor.

In this case you can identify that:

(a,b) = (1,1)

k = 3

Therefore, susbtituting values into the formula shown above, you get that the coordinates ot the resulting triangle D'E'F, are the following:

Vertex D' → \((3(-2-1) +1, 3(1-1) +1) = (-8, 1)\)

Vertex E' → \((3(2-1) +1, 3(4-1) +1) =(4,10)\)

Vertex F' →\((3(3-1) +1, 3(1-1) +1) =(7,1)\)

hence the vertex of ▲D'E'F' are (D' → ( -8, 1),  E' → (4, 10), F' → (7, 1).)
