A linear inequality to represent this scenario is: D. y ≥ 2.85x

In Mathematics, an inequality simply refers to a mathematical relation that can be used to compare two (2) or more numerical values, numbers, and variables in an algebraic equation, especially based on any of the following inequality symbols:

In order to write a linear inequality to describe this situation, we would assign variables to the price of gasoline and Ameena's family budget respectively, and then translate the word problem into algebraic equation as follows:

Since the price of gasoline cannot be greater than Ameena's family budget, the linear inequality to represent this is as follows:

y ≥ 2.85x

In conclusion, we can logically deduce that Ameena's family budget would always be greater than the price of gasoline, irrespective of the economic situation.

Answer:

\(x-3\)

Step-by-step explanation:

The area of the flagpole base is \(x^2-6x+9\ \text{yd}\)

where the factor of the equation is the length of the base.

In order to find the length we need to factorize the equation

\(x^2-6x+9\)

\(=x^2-3x-3x+9\)

\(=x(x-3)-3(x-3)\)

\(=(x-3)(x-3)\)

The length of the base of the flagpole is \((x-3)\ \text{yd}\).

The area of a square base is the product of the side lengths.

The length of the base is x - 3

The area is given as:

\(\mathbf{Area =x^2 - 6x + 9}\)

Expand

\(\mathbf{Area =x^2 - 3x - 3x + 9}\)

Factorize

\(\mathbf{Area =x( x- 3) - 3(x - 3)}\)

Factor out x - 3

\(\mathbf{Area =( x- 3) (x - 3)}\)

Express as squares

\(\mathbf{Area =( x- 3)^2}\)

Rewrite the area as:

\(\mathbf{Length^2 =( x- 3)^2}\)

Take square roots of both sides

\(\mathbf{Length =x- 3}\)

Hence, the length of the base is x - 3

To find the number of dimes and quarters, you have 17 dimes and 34 quarters in your pocket , when there are 51 coins in your pocket.

To solve this problem, we can set up a system of equations using the given information. Let's use "d" to represent the number of dimes and "q" to represent the number of quarters.

We know that there are 51 coins in total, so we can write the equation: d + q = 51.

We also know that the total value of the coins is $10.20, which can be expressed as 10d + 25q (since dimes are worth 10 cents and quarters are worth 25 cents). So our second equation is: 10d + 25q = 1020.

To solve this system of equations, we can use substitution or elimination. Let's use substitution:

Rearrange the first equation to solve for d: d = 51 - q.

Substitute this expression for d in the second equation: 10(51 - q) + 25q = 1020.

Simplify and solve for q: 510 - 10q + 25q = 1020.

Combine like terms: 15q = 510.

Divide both sides by 15: q = 34.

Now substitute this value back into the first equation to solve for d: d + 34 = 51.

Subtract 34 from both sides: d = 17.

Therefore, you have 17 dimes and 34 quarters.

Jason has to spend 60% of his money on expenses.

Percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol % (percent) and is used to describe the relative size or amount of something.

To find the percentage of Jason's money that he has to spend on expenses, we can use the following formula:

Percentage = (Expense / Salary) x 100%

Substituting the given values, we get:

Percentage = (18,000 / 30,000) x 100%

Percentage = 0.6 x 100%

Percentage = 60%

Therefore, Jason has to spend 60% of his money on expenses.

For example, if you have a class of 30 students and 20 of them are girls, you could say that the percentage of girls in the class is:

20/30 x 100% = 66.67%

This means that 66.67% of the students in the class are girls.

Answer:

156 cm³

Step-by-step explanation:

The solid is a prism with a trapezoid base.

volume = (area of base) × height

V = (8 cm + 5 cm)(1/2)(4 cm) × 6 cm

V = 156 cm³

We can use the logarithmic identity log_a(b) + log_a(c) = log_a(bc) to simplify the left side of the equation:

log_2(x) + log_4(x+1) = log_2(x) + log_2((x+1)^(1/2))

Using the rule log_a(b^c) = c*log_a(b), we can simplify further:

log_2(x) + log_2((x+1)^(1/2)) = log_2(x(x+1)^(1/2))

Now we can rewrite the equation as:

log_2(x(x+1)^(1/2)) = 3

Using the rule log_a(b^c) = c*log_a(b), we can rewrite this as:

x(x+1)^(1/2) = 2^3

Squaring both sides, we get:

x^2 + x - 8 = 0

This is a quadratic equation that can be solved using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 1, and c = -8. Plugging in these values, we get:

x = (-1 ± sqrt(1^2 - 4(1)(-8))) / 2(1)

x = (-1 ± sqrt(33)) / 2

x ≈ -2.54 or x ≈ 3.54

However, we must check our solutions to make sure they are valid. Plugging in x = -2.54 to the original equation results in an invalid logarithm, so this solution is extraneous. Plugging in x = 3.54 yields:

log_2(3.54) + log_4(4.54) = 3

0.847 + 0.847 = 3

So x = 3.54 is the valid solution to the equation.

The equation of the parabola from the vertex is f(x) = -3(x - 5)² + 9

The equation of the function is given as

f(x) = 3x²

Also, we have

Vertex = (5, 9)

The form of the equation is given as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

This means that

Vertex = (h, k) = (5, 9)

Substitute (h, k) = (5, 9) in the equation f(x) = a(x - h)² + k

So, we have

f(x) = a(x - 5)² + 9

This also means that

f(x) = -3(x - 5)² + 9

The -3 is gotten from f(x) = -3x²

Hence, the equation of the parabola is f(x) = -3(x - 5)² + 9

In this type of problem. You need to determine first the unit dimension..

The dimension of the volume is in cubic so the unit dimension will be the cube root the volume:

Let u = unit dimension

So we now have the unit dimension, dilating it with a scale factor of k will give as a new volume. Since it is a unit dimension, you need to take the cube of it so you will arrive with the new volume.

So the new volume will be :

or just simply :

Solving for the scale factor k :

So now we have the scale factor of k = 4

Now for the Surface Area , the dimension of it is in square units, so the unit dimension will be the square root of the surface area :

It has almost the same formula for k, but the difference is only the cube root or the square root.

Answer:

\(y = \frac{1}{2}x + \frac{3}{2}\)

Step-by-step explanation:

Assuming this is a linear equation in the form of \(y = mx + b\), we can first solve for the slope using \(\frac{y_2 - y_1}{x_2 - x_1}\), for these points, the slope would be \(\frac{1}{2}\). Now we plug in the points to get the equation:

plugging in (7,5), we get \(5 = \frac{1}{2}\) ×\(7\) + \(b\)

and solving for b, we get b = \(\frac{3}{2}\)

therefore, the equation of the line passing through (7,5) and (1,2) is \(y = \frac{1}{2}x + \frac{3}{2}\).

The annual interest rate on this loan is 4.8%.

Simple interest is defined as the interest obtained over the principal amount on a certain rate.

Given that,

Principal amount, P = $500,000

Loan term, t = 15 years

Loan payment = $4,778.26 per month

                        = $57339.12 per year

                        = $860,086.8 in 15 years

We know that final amount for simple interest is,

A = P(1 + r t)

860,086.8 = 500,000(1 + 15r)

1.7201736 = 1 + 15r
