Answer: x = 1

Step-by-step explanation: When we have this kind of setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

So first, let's put our variables together on the left side

by subtracting 2x from both sides of the equation.

That gives us 3x + 9 = 12.

Now we can move our numbers to the right by

subtracting 9 from both sides and we get 3x = 3.

Now divide both sides by 3 and x = 1.

Answer:hope this helps

0.75x + 3 = 0.25x + 5.25

Constants are $3 and $5.25 respectively

Topping costs $0.75 and $0.25 respectively

To have same cost the toppings number would be different as cost is different.

Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:

0.75x + 3 = 0.25y + 5.25

Constants are $3 and $5.25 respectively

The continuous interest rate at which the money was invested is approximately 13.3%.

We can use the formula for compound interest in continuous compounding, which is given by the equation:

\(A = Pe^{rt}\)

Where:

A = Final amount (the value of the trust fund when Emily turned 18)

P = Principal amount (the initial investment)

e = Euler's number (approximately 2.71828)

r = Continuous interest rate

t = Time in years

In this case, we have the following information:

P = $25,000

A = $100,000

t = 18 years

We can rearrange the formula to solve for the continuous interest rate (r):

r = ln(A/P) / t

Substituting the given values:

r = ln(100,000/25,000) / 18

Calculating this expression:

r ≈ ln(4) / 18 ≈ 0.133 ≈ 13.3%

Therefore, the continuous interest rate at which the money was invested is approximately 13.3%.

because they have 3 sides

Step-by-step explanation:

The three ordered pairs for the equation y = -4x+3 are (0,3), (1,-1) and (2,-5).

According to the question,

We have the following equation:

y = -4x+3

We have to find the three ordered pairs when the values of x are given in the table.

When x = 0, we have the following value of y:

y = -4*0+3

y = 3

When x = 1:

y = -4*1+3

y = -4+3

y = -1

When x = 2:

y = -4*2+3

y = -8+3

y = -5

Hence, the three ordered pairs for the equation y = -4x+3 are (0,3), (1,-1) and (2,-5).

The mean of the total length is 36 inches, and the standard deviation is 0.17 inches. This means that on average, the total length of the sticks will be 36 inches, and there will be a variation of approximately 0.17 inches around this mean length.

The mean of the total length for both Alex and Brandon can be determined by multiplying the mean length of a single stick by the number of sticks required for each toy. In this case, each toy requires four 9-inch long sticks.

Mean of the total length for both Alex and Brandon: 4 sticks * 9 inches = 36 inches.

Since both Alex and Brandon have sticks with the same mean length and standard deviation, the standard deviation of the total length for both of them remains the same.

Standard deviation of the total length for both Alex and Brandon: 0.17 inches.

Therefore, The mean of the total length is 36 inches, and the standard deviation is 0.17 inches. This means that on average, the total length of the sticks will be 36 inches, and there will be a variation of approximately 0.17 inches around this mean length.

The first term of the arithmetic sequence is 4.In an arithmetic sequence with a common difference of 3, if the sum of the first 20 terms is 650, we need to find the first term of the sequence.

Let's denote the first term of the arithmetic sequence as 'a' and the common difference as 'd'. The formula to find the sum of the first n terms of an arithmetic sequence is given by:

\(\text{Sum} = \frac{n}{2} \cdot (2a + (n-1)d)\)

We are given that the common difference is 3 and the sum of the first 20 terms is 650. Plugging these values into the formula, we have:

\(650 = \frac{20}{2} \cdot (2a + (20-1) \cdot 3)\)

Simplifying the equation:

650 = 10 * (2a + 19*3)

65 = 2a + 57

2a = 65 - 57

2a = 8

a = 8/2

a = 4

Therefore, the first term of the arithmetic sequence is 4.

Step-by-step explanation:

Let us assume the number of pages left be x

And, the number of hours is x

According to the question

Data given is as follows

Number of hours 1.5 and 5

Total pages 480

Left pages 402

Step-by-step explanation:

Perpendicular lines have slope that are negative reciprocals, so the slope of the line we want to find is 1/7.

The equation in point-slope form is \(y-21=\frac{1}{7}(x-14)\).

Rearranging into slope-intercept form,

\(y-21=\frac{1}{7}x-2 \\ \\ y=\frac{1}{7}x+19\)

Using triangle proportionality AB/AD is proportional to BC/CD. Using the isosceles triangle in the construction EC = EB.

These lead to the proportion that corresponds to the angle bisector theorem of AB/AD = AC/CD.

The angle bisector theorem states that the angle bisector of a triangle divides the opposite side into segments that are proportional to the other two sides of the triangle. This theorem can be proven using triangle similarity and the concept of proportionality.

Let ABC be a triangle with angle bisector AD, where D lies on BC. To show that AB/BD = AC/CD.

First, use the fact that triangles ABD and ACD are similar by angle-angle-angle similarity, since they share two congruent angles (angle A and angle BAD is congruent to angle CAD by the angle bisector theorem). Therefore:

AB/AD = BD/CD (by the definition of similar triangles)

Cross-multiplying gives:

AB × CD = AD × BD

Similarly, use the fact that triangles ABC and ABD are similar:

AB/AC = BD/CD

Cross-multiplying gives:

AB × CD = AC × BD

Combining these two equations:

AB × CD = AD × BD = AC × BD

Dividing both sides by BD gives:

AB/BD = AC/CD

Therefore, the angle bisector theorem is proven.

Therefore, the vector form of the equation y = x² - 8x + 15 is y = (x - 4)² + 14. The vertex of the parabola is at the point (4, 14).

To convert the quadratic equation y = x² - 8x + 15 from standard form to vertex form, we need to complete the square by adding and subtracting a constant term. Here's the step-by-step explanation:

Factor the coefficient of x²: The coefficient of x² is 1, so we don't need to factor it.

Group the x terms: Rewrite the quadratic equation as y = (x² - 8x) + 15.

Complete the square: To complete the square, we need to add and subtract a constant term that will make the expression inside the parentheses a perfect square trinomial. The constant we need to add is half of the coefficient of x, squared: (8/2)² = 16.

y = (x² - 8x + 16 - 16) + 15 // add and subtract 16

y = (x - 4)² - 1 + 15 // factor and simplify

Simplify: Now we can simplify the expression by combining the constants -1 and 15 to get 14.

If the null hypothesis is rejected, and the proportion of customers willing to pay more is significantly different from 10%, this would support my hypothesis that customers are willing to pay more for eco-friendly packaging.

Let's say you work for a company that has been using a certain type of packaging material for their products. However, there have been concerns raised about the environmental impact of this material, and the company is considering switching to a more eco-friendly option. You believe that customers would be willing to pay more for products that are packaged with the eco-friendly material, but you need to test this hypothesis.

Variable: The variable that would be tested is whether customers are willing to pay more for products that are packaged with the eco-friendly material.

Guess of value: I would guess that customers would be willing to pay more for eco-friendly packaging, but I'm not sure how much more. Let's say my guess is that customers would be willing to pay 10% more for products packaged with the eco-friendly material.

Hypothesis test: To test this hypothesis, I would conduct a survey where I randomly select a sample of customers and ask them if they would be willing to pay more for products packaged with the eco-friendly material. I would then compare the proportion of customers who are willing to pay more to my guess of the value (10%).

Null hypothesis: The null hypothesis would be that the proportion of customers willing to pay more for eco-friendly packaging is not significantly different from 10%.

Alternative hypothesis: The alternative hypothesis would be that the proportion of customers willing to pay more for eco-friendly packaging is significantly different from 10%.

 If the null hypothesis is not rejected, this would suggest that customers are not willing to pay more for eco-friendly packaging, and the company may need to reconsider their decision to switch to the more expensive material.

That when (x, y) = (0, 0), the function is defined to be 0, which corresponds to the origin in polar coordinates.

To describe the level curves of the function defined by f(x, y) = 2xy / (x^2 + y^2), where (x, y) ≠ (0, 0) and f(0, 0) = 0, we can convert the Cartesian coordinates (x, y) to polar coordinates (r, θ).

In polar coordinates, x = r cos(θ) and y = r sin(θ). Substituting these expressions into the function, we have:

f(r, θ) = 2(r cos(θ))(r sin(θ)) / (r^2 cos^2(θ) + r^2 sin^2(θ))

= 2r^2 cos(θ) sin(θ) / (r^2)

= 2r cos(θ) sin(θ)

Simplifying further, we get:

f(r, θ) = 2r cos(θ) sin(θ)

Now, let's consider the level curves, which are the curves in the xy-plane where f(x, y) is constant. In polar coordinates, this means we need to find values of r and θ such that f(r, θ) is constant.

Since f(r, θ) = 2r cos(θ) sin(θ), we can set a constant value k and rewrite the equation as:

k = 2r cos(θ) sin(θ)

Dividing both sides of the equation by 2 and rearranging, we have:

r = k / (2 cos(θ) sin(θ))

This equation represents the level curves of the function f(x, y) = 2xy / (x^2 + y^2) in polar coordinates. The level curves are given by the equation r = k / (2 cos(θ) sin(θ)), where k is a constant.

Note that when (x, y) = (0, 0), the function is defined to be 0, which corresponds to the origin in polar coordinates.
