Answer:

The answer to your question is A coordinate plane with a line passing through (0, -3) and (2,0)

Step-by-step explanation:

Line

                             3x - 2y = 6

Solve for y

                              -2y = -3x + 6

                                 y = 3/2 x - 3

Find "y" when x = 0

                                 y = 3/2(0) - 3

                                 y = -3                      Point (0, -3)

Find "x" when y = 0

                                0 = 3/2x - 3

                                 3 = 3/2 x

                                x = 6/3

                                x = 2                       Point (2, 0)

The graph of the equation 3x - 2y = 6 passes through the points (0, -3) and (2, 0). This conclusion is reached after rearranging the equation into the slope-intercept form and comparing the slope and the y-intercept with coordinates of the given lines.

To find the correct graph for the equation 3x - 2y = 6, we first need to rearrange the equation in the slope-intercept form (y = mx + b), where m is the slope of the line and b is the y-intercept.

We rearrange our equation as follows: 3x - 6 = 2y. Simplifying, we get y = 1.5x - 3.

This equation tells us that the y-intercept (where the line crosses y-axis) is -3, and the slope is 1.5, in other words, for each step in positive x-direction, y increases by 1.5 steps.

Now looking at our coordinate plane options, the graph that fits this description is the one with a line passing through the points (0, -3) and (2, 0). Hence, this is the graph of the given equation.

Answer:

Step-by-step explanation:

Let L represent the length of the rectangle.

Let W represent the width of the rectangle.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of a rectangle is 48 in. It means that

48 = 2(L + W)

L + W = 48/2

L + W = 24 - - - - - - - - - 1

the length of the rectangle is 6 in greater than the width. It means that

L = W + 6

Substituting L = W + 6 into equation 1, it becomes

W + 6 + W = 24

2W + 6 = 24

2W = 24 - 6 = 18

W = 18/2 = 9

L = W + 6 = 9 + 6 = 15

Final answer:

The student's problem involves finding the length and width of a rectangle given its perimeter and the fact that the length is 6 inches greater than the width. To solve it, we defined the width as a variable, set up an equation based on the perimeter, and used substitution to find that the width is 9 inches and the length is 15 inches.

Explanation:

The perimeter of a rectangle is given by the formula 2(length + width). In the stated problem, we are given the total perimeter (48 inches) and told that the length is 6 inches greater than the width. We can define the width as w and the length as w + 6. So, the perimeter equation is:

2(w + (w + 6)) = 48

Now that we have the width, we can find the length using substitution:

w + 6 = 9 + 6 = 15

Therefore, the width is 9 inches and the length is 15 inches.

Answer:

729

Step-by-step explanation:

The first term is 1 in the geometric sequence 1, −3, 9, −27, . .

First find out the nth term formula for the geometric sequence

[tex]a_n=a_1(r)^{n-1}[/tex]

where a_1 is the first term =1

r is the common ratio,

[tex]\frac{-3}{1}=-3[/tex]

[tex]\frac{9}{-3}=-3[/tex]

[tex]\frac{-27}{9}=-3[/tex]

r=-3, a_1=1

[tex]a_n=a_1(r)^{n-1}[/tex]

[tex]a_n=1(-3)^{n-1}[/tex]

Now find out the seventh term, n=7

[tex]a_7=1(-3)^{7-1}=729[/tex]

To find the seventh term of the geometric sequence 1, −3, 9, −27, ..., we calculate the common ratio and use it in the formula for the n-th term. The common ratio is −3 and the seventh term turns out to be 729. So the correct option is  E.

Calculating the SEVENTH Term of a Geometric Sequence

The given geometric sequence is 1, −3, 9, −27, ... and we are asked to find the seventh term. In a geometric sequence, each term after the first is found by multiplying the previous term by a constant called the common ratio (r). To find the common ratio, we can divide the second term by the first term, or the third term by the second term, and so on.

Common ratio (r) calculation:
Divide the second term (−3) by the first term (1), which gives us r = −3.

To find the seventh term, we use the formula for the n-th term of a geometric sequence, which is:
a_n = a_1 × r^(n-1), where a_n is the n-th term, a_1 is the first term, and n is the term number.

Seventh term calculation:
a_7 = 1 × (−3)^(7-1) = 1 × (−3)^6. Since −3 to an even power is positive, the answer is 1 × 3^6 = 729.

Therefore, the seventh term of the geometric sequence is 729.

Answer:

Step-by-step explanation:

Let x represent the number of miles with either company A or company B.

Company A charges ​$70.50 and 18 cents per mile. Converting 18 cents to dollars, it becomes

18/100 = $0.18

Total cost of x miles with company A would be

0.18x + 70.50

Company B charges $30.50 and 11 cents per mile. Converting 11 cents to dollars, it becomes

11/100 = $0.11

Total cost of x miles with company B would be

0.11x + 30.50

For the amount that company A charges more than company B, it becomes

0.18x + 70.50 - 0.11x + 30.50

0.18x - 0.11x + 70.5 - 30.5

0.07x + 40

Company A charges 0.07x + 40 more than company B

Answer:

Area of each tile = 19.5 inches^2

Step-by-step explanation:

Rhombus:-

A rhombus is a type of quadrilateral whose opposite sides are parallel and equal.Also, the opposite angles of a rhombus are equal and the diagonal intersect each other perpendicularly.

To find the area of a rhombus when the measures of its height and side length are given, use the formula

A = Base X height

Area of a rhombus = 6.5 X  3

                          A      = 19.5 inches^2

The area of each rhombus-shaped tile is 19.5 square inches for the given dimensions. Thus, each tile has an area of 19.5 square inches.

To find the area of a rhombus, you can use the formula

⇒ Area = base × height

In this case, the height is given as 3 inches and the length of each side is 6.5 inches, but the length of the sides is not needed, as we are working with the base and height directly.

So, the area can be calculated as follows:

⇒ Base = 6.5 inches

⇒ Height = 3 inches.

⇒ Area = base × height.

⇒ Area = 6.5 inches × 3 inches

= 19.5 square inches.

Therefore, the area of each rhombus-shaped tile is 19.5 square inches.

Final answer:

To find the total cost of an iPad that is on sale at 15% off with a 6% sales tax, calculate the discount, subtract it from the original price, determine the sales tax, and add it to the discounted price.

Explanation:

To find the total cost of the iPad:

Calculate the discount: $720 * 15% = $108 discount

Subtract the discount from the original price: $720 - $108 = $612

Calculate the sales tax: $612 * 6% = $36.72

Add the sales tax to the discounted price: $612 + $36.72 = $648.72

Answer:the equation relating E to H is

E = 20H

Step-by-step explanation:

Let E represent her earnings (in dollars) after tutoring for H hours.

For each hour that she tutors, she earns 20 dollars. This means that in H hours, her total earnings would be

E = 20H

To find Mai's earnings after tutoring for 17 hours, we would substitute H = 17 into the equation. It becomes

E = 20 × 17

E = $340

Mai's earnings [tex](\(E\))[/tex] after tutoring for 17 hours would be $340, calculated as [tex]\(E = 20 \times 17\).[/tex]

To relate Mai's earnings [tex](\(E\))[/tex] to the number of hours she tutors [tex](\(H\))[/tex], we can use the following equation:

[tex]\[E = 20H\][/tex]

This equation represents that Mai earns $20 for each hour she tutors. By multiplying the number of hours [tex](\(H\))[/tex] by the rate of $20 per hour, we get her total earnings [tex](\(E\))[/tex].

Now, to find Mai's earnings after tutoring for 17 hours, we can plug in [tex]\(H = 17\)[/tex] into the equation:

[tex]\[E = 20 \times 17\][/tex]

[tex]\[E = 340\][/tex]

So, Mai's earnings after tutoring for 17 hours would be $340.

Answer:the point slope form is

y + 1 = - 1/2(x - 6)

Step-by-step explanation:

The point slope form of a line is expressed as

y - y1 = m(x - x1)

Where

m represents the slope of the line.

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

From the information given,

slope, m = - 1/2

y1 = - 1

x1 = 6

Therefore, the point slope eqy would be

y - - 1 = - 1/2(x - 6)

y + 1 = - 1/2(x - 6)

Answer:

y - - 1 = - 1/2(x - 6)

y + 1 = - 1/2(x - 6)

Step-by-step explanation:

When y = 3, the value of z is 2.

Since x is directly proportional to y and inversely proportional to z, we can write this relationship as:
[tex]x = k \frac{y}{z}[/tex]
where k is a constant of proportionality.

We are given the values x = 3, y = 6, and z = 4. Let's use these values to find k.

[tex]3 = k \frac{6}{4}[/tex]

Simplifying this, we get:

[tex]3 = k \cdot 1.5[/tex]

Solving for k:

[tex]k = \frac{3}{1.5} = 2[/tex]

Now we know the constant k. We can use it to find z when y = 3.

We know the relationship:

[tex]x = 2 \frac{y}{z}[/tex]

We need to find z when x = 3 and y = 3.

[tex]3 = 2 \frac{3}{z}[/tex]

Rearranging to solve for z:

[tex]3 = 6 \div z[/tex]

[tex]z = 2[/tex]

The truck, experiencing a force of 1500 N, skids a distance of 25 meters, resulting in a change in kinetic energy of 37,500 J. Now, let's break down the concept of kinetic energy and the given data:

Definition of Kinetic Energy:

Kinetic energy, in physics, is the energy possessed by a moving object.

It represents the effort required to accelerate an object of a specific mass from rest to a particular velocity.

The body retains its kinetic energy even with slight speed variations, maintaining the energy acquired during acceleration.

Kinetic Energy Conservation:

When the body decelerates from its current velocity to a state of rest, the same amount of energy is expended.

Formal Definition:

Kinetic energy is formally described as any quantity exhibiting a gradient with respect to time in the Lagrangian of a system.

Given Data:

Force (F) = 1500 N

Distance (d) = 25 m

Calculation of Change in Kinetic Energy:

Utilize the formula for change in kinetic energy: ΔK.E = F × d

Substitute the values: ΔK.E = 1500 × 25

This results in ΔK.E = 37,500 J.

Therefore, the observed change in kinetic energy for the truck, moving a distance of 25 meters with a force of 1500 N, is precisely 37,500 J.

Answer:

J < T - 5

Step-by-step explanation:

T =  The number of juice boxes Thomas had

J =  The number of juice boxes Thomas gave to his sisters

Thomas had 12 juice boxes

T = 12

He gave some to his sisters he now has more than 5 left.

T - J > 5

-J > 5 - T

J < -5 + T

J < T - 5

To determine the number of juice boxes Thomas gave to his sisters, the inequality 12 - j > 5 is used, which simplifies to j < 7, indicating that he gave away fewer than 7 juice boxes.

To find j, the number of juice boxes Thomas gave to his sisters, we start with the total number he had initially, which is 12. We know that he gave away some juice boxes and still has more than 5 left. If we let j represent the number of juice boxes given to his sisters, then 12 - j > 5 would be the inequality that can be used to determine j.

Since Thomas has more than 5 left, but we don't know the exact number, we use the inequality to represent the situation. Therefore, if we solve the inequality, subtracting 5 from both sides, we get j < 7. This means that Thomas gave away fewer than 7 juice boxes to his sisters because he had more than 5 remaining.

The distance between the harbor and the island is 20 nautical miles.

To find the distance between the harbor and the island, we need to calculate the average speed of the motorboat for the entire trip. Since the average speed on the outbound trip was 10 knots and the average speed on the return trip was also 10 knots, we can conclude that the boat traveled at a constant speed throughout the trip. Let's assume the distance between the harbor and the island is 'd'.

Since speed = distance / time, we can calculate the time taken for each leg of the trip using the average speeds and the total time of 4.0 hours:

Time taken for the outbound trip = d / 10 knots

Time taken for the return trip = d / 10 knots

Since the total time is 4.0 hours, we can write the equation: d / 10 + d / 10 = 4.0

Simplifying the equation, we get: 2d / 10 = 4.0

Multiplying both sides by 10, we get: 2d = 40

Dividing both sides by 2, we get: d = 20

Therefore, the distance between the harbor and the island is 20 nautical miles.
