Write the expanded form of the expression. ​y(3.05x−3.75​)−2.25y

Answer:

(-3/2, -13/2)

Step-by-step explanation:

To solve the system of equations graphically, we need to plot the two equations on the same set of axes and find the point of intersection.

To plot the first equation y = x - 5, we can start by finding the y-intercept, which is -5. Then, we can use the slope of 1 (since the coefficient of x is 1) to find other points on the line. For example, if we move one unit to the right (in the positive x direction), we will move one unit up (in the positive y direction) and get the point (1, -4). Similarly, if we move two units to the left (in the negative x direction), we will move two units down (in the negative y direction) and get the point (-2, -7). We can plot these points and connect them with a straight line to get the graph of the first equation.

To plot the second equation y = -x - 8, we can follow a similar process. The y-intercept is -8, and the slope is -1 (since the coefficient of x is -1). If we move one unit to the right, we will move one unit down and get the point (1, -9). If we move two units to the left, we will move two units up and get the point (-2, -6). We can plot these points and connect them with a straight line to get the graph of the second equation.

The point of intersection of these two lines is the solution to the system of equations. We can estimate the coordinates of this point by looking at the graph, or we can use algebraic methods to find the exact solution. One way to do this is to set the two equations equal to each other and solve for x:

x - 5 = -x - 8 2x = -3 x = -3/2

Then, we can plug this value of x into either equation to find the corresponding value of y:

y = (-3/2) - 5 y = -13/2

So the solution to the system of equations is (-3/2, -13/2).

As x approaches infinity in the function f(x) = log4x, the logarithmic function grows more slowly as its input increases. In the limit as x approaches infinity, the logarithm also approaches infinity.

This is because the logarithm function represents the power to which the base (in this case, 4) must be raised to obtain the input value (x).

Logarithms are indeed widely used in mathematics to solve equations involving exponents or powers.

They provide a way to transform equations into simpler linear equations.

Logarithms also have applications in various fields such as physics, engineering, and computer science,

where they are used to represent numbers, measure data, and solve problems involving exponential growth or decay.

Your understanding of the behavior of logarithmic functions and their applications is accurate.

Before the fifth house, there is a 75% probability of finding a house with a dog. This is due to the fact that a dog is likely to be present in a home 60% of the time, or in 3 out of every 5 homes.

The likelihood that a dog will be in a house before the sixth house is determined by that likelihood. If there is a 60% chance that a home has a dog, then 3 out of every 5 homes have a dog. There is a 3/5 chance that we will find a home with a dog if we consider 4 houses before the fifth. P(A) = 1 - (1-P(A))n, where P(A) is the probability of finding a house with a dog before the fifth house and n is the number of houses, can be used to determine the likelihood of discovering one before the fifth house (4 in this case). Hence, P(A) is equal to 1 - (1 - 0.6)4 = 0.75, or 75%. This indicates that before the sixth house, there is a 75% chance that you will locate a home with a dog.

you should invest approximately $500,000 today at 9% simple interest to reach your retirement goal of $1,175,000 in 15 years.

To determine how much you should invest today at 9% simple interest to reach your retirement goal of $1,175,000 in 15 years, we can use the formula for simple interest:

A = P(1 + rt)

Where A is the future value, P is the principal (the amount you should invest today), r is the interest rate, and t is the time in years.

We can rearrange the formula to solve for P:

P = A / (1 + rt)

Plugging in the values, we have:

P = 1,175,000 / (1 + 0.09 * 15)

P = 1,175,000 / (1 + 1.35)

P = 1,175,000 / 2.35

P ≈ $500,000

Therefore, you should invest approximately $500,000 today at 9% simple interest to reach your retirement goal of $1,175,000 in 15 years.

Line f is 4 units from the x-axis.

The cheese slice you found in your garage is approximately 46.36 days old, based on the given decay rate and the percentage of its original size.

Let's start by denoting the initial size of the cheese slice as S, and the remaining size found as R. Given that the cheese slice is 13.6% of its original size, we can represent this as:

R = 0.136 * S

Now, let's consider the decay rate of the cheese, which is given as 0.0386. Assuming that the cheese decay follows exponential decay, we can write the formula for the decay as:

R = S * (1 - decay_rate) ^ t

Where 't' is the age of the cheese in days. We can now substitute the value of R in the decay formula:

0.136 * S = S * (1 - 0.0386) ^ t

Since we're interested in finding 't', we can simplify the equation by dividing both sides by S:

0.136 = (1 - 0.0386) ^ t

Now, to solve for 't', we can take the natural logarithm of both sides:

ln(0.136) = ln((1 - 0.0386) ^ t)

Using the logarithmic property, we get:

ln(0.136) = t * ln(1 - 0.0386)

Finally, divide both sides by ln(1 - 0.0386) to find 't':

t = ln(0.136) / ln(1 - 0.0386)

Using a calculator, we find that t ≈ 46.36 days.
