dogs = x

cats = y

x+y =39

x- y = 13

so add the 2 equations together you get 2x = 52 so x = 26

y = 13

The sum is x/(x+5) + (x+10)/(x+1).

The difference is x/(x+5) - (x+10)/(x+1).

What is simplification?

To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue.

Here, we have

Given: x/(x+5) + (x²+20x+100)/(x²+11x+10)

Sum:

= x/(x+5) + (x²+20x+100)/(x²+11x+10)

= x/(x+5) + (x+10)²/(x+1)(x+10)

=  x/(x+5) + (x+10)/(x+1)

Hence, the sum is x/(x+5) + (x+10)/(x+1).

Now, the difference:

= x/(x+5) - (x²+20x+100)/(x²+11x+10)

= x/(x+5) - (x+10)²/(x+1)(x+10)

= x/(x+5) - (x+10)/(x+1)

Hence, the difference is x/(x+5) - (x+10)/(x+1).

An equation, in its most basic form, is a mathematical statement that states that two mathematical expressions are equal. For example, 3x + 5 = 14 is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.

Here,

The number of real solutions for each system of equations can be determined by counting the number of points where the lines or curves intersect.

System A:

The equation x² + y² = 17 defines a circle with center at the origin and radius √17. The equation y = -1/2x defines a line. Since the circle and line intersect at two points, the system of equations has two real solutions.

Number of real solutions for System A: 2

System B:

The equation y = x² defines a parabola. The equation 7x + y = -6x + 5 defines a line. Since the parabola and line intersect at exactly one point, the system of equations has one real solution.

Number of real solutions for System B: 1

System C:

The equation y = 2x² + 9 defines a parabola. The equation 8y - 17 = 0 defines a line. Since the parabola and line intersect at exactly one point, the system of equations has one real solution.

Answer:

To find Sally's yearly salary, we can use the information that her budget for food is 1/8 of her yearly salary and her total food bill for the year is $12,500. Let's call Sally's yearly salary "S".

Since 1/8 of Sally's yearly salary is dedicated to food, we can write:

S * 1/8 = $12,500

To solve for S, we can divide both sides of the equation by 1/8:

S = $12,500 * 8 = $100,000

So, Sally's yearly salary is $100,000.

As a result, the rate of change is -60 miles per hour. This indicates that Valerie's distance from Houston drops by 60 miles per hour.

Slope is a measure of the steepness of a line or the rate of change between two variables. In mathematics, slope is often represented by the letter "m". The slope of a line is the ratio of the change in the vertical coordinate (rise) to the change in the horizontal coordinate (run) between two points on the line. The slope has important properties and interpretations. A slope of zero indicates a horizontal line, a positive slope indicates an upward slope, and a negative slope indicates a downward slope. The slope can also be used to determine whether two variables are positively or negatively correlated. In addition to its use in describing lines, slope is also used in other areas of mathematics, such as in the study of graphs of functions and in calculus. The slope of a function at a specific point is known as the derivative of the function, and it is used to study the rate of change and the concavity of the function.

Here,

The rate of change can be determined by finding the slope of the line that represents the function. In this case, we can use the given information to write an equation for the function and then find its slope.

Let's call the number of hours she drives z and the distance from Houston y. Based on the information given, we know that after 3 hours, her distance from Houston is 60 miles:

y = 60 miles

z = 3 hours

And we know that her distance from Houston decreases by 120 miles every 2 hours:

Δy = -120 miles

Δz = 2 hours

So the rate of change, or slope, is given by:

slope = Δy/Δz = -120/2 = -60

So the rate of change is -60 miles per hour. This means that for every hour that passes, Valerie's distance from Houston decreases by 60 miles.

Simple interest is computed on a loan's principal, or initial loan amount.

Compound interest is often referred to as "interest on interest" since it is calculated using both the principal and the accrued interest from prior periods.

Formula for simple interest - S.I. = (P × T × R) ⁄ 100

Formula for compound interest - C.I. = P(1+R⁄100)t − P

Sampling distributions are a fundamental concept in statistics. They describe the distribution of sample statistics, such as means and proportions, over many samples of the same size taken from the same population. Sampling distributions provide essential information about the variability and stability of these sample statistics and help us make inferences about the population parameters.

The central limit theorem states that, as the sample size increases, the distribution of the sample means approaches a normal distribution, regardless of the shape of the population distribution. We can use regular distribution models to predict the sample mean and estimate the population means with confidence intervals.

In addition to the central limit theorem, other essential concepts in sampling distributions include the law of large numbers, which states that the average of the sample means approaches the population means as the sample size increases, and the standard error of the mean, which is a measure of the variability of the sample mean.

Knowing about sampling distributions is essential for understanding statistical inference and for making informed decisions about populations based on sample data. They provide a framework for evaluating the reliability and accuracy of sample statistics, and they play a crucial role in hypothesis testing, estimation, and other data analysis techniques.

The probability of getting all tails in 9 coin flips is (1/2)^9, which is approximately equal to 0.02.

The probability of getting all tails in 9 coin flips can be calculated by multiplying the probability of getting tails on each individual flip. Since the coin is fair, the probability of getting tails on a single flip is 1/2. Hence, the probability of getting all tails in 9 coin flips is given by (1/2)^9, which is approximately equal to 0.02. This means that there is a 2% chance of getting all tails in 9 coin flips.

It is important to note that in a sequence of coin flips, the order in which the heads and tails appear is important. For example, getting HTTTHTTTT and THTTTHTTT are two different outcomes, even though both have the same number of heads and tails. The total number of possible outcomes in 9 coin flips is 2^9, which is equal to 512. So, to calculate the probability of getting all tails in 9 coin flips, we need to calculate the number of possible outcomes with 9 tails, divide that number by the total number of possible outcomes, and obtain (1/2)^9.
