Answer: infinitely many solutions

Step-by-step explanation:

First we want to arrange the linear equations such that its in the form

y = ax + b

For the first equation we subtract x from both sides to get:

y= -x + 1

For the second equation we divide by 3 to get:

y = -x + 1

These two equations are the same line so there are infinitely many solutions

The given system of equations have infinitely many solutions.

A solution of a system of equations is a list of numbers i.e. the value of variables that make all the of the equations true simultaneously.

What is slope intercept form of a line?

The slope intercept form of the line is y = mx + b, where m is the slope and b is y intercept.

If there is no intercept difference between them ( intercept of two lines or system of equations) , then the line coincide to each other.

A system of linear equations is a set of equations which are satisfied by the same set of variables.

The solution to a system of linear equation is the point at which the lines representing the linear equation intersect.

According to the given question

We have , a system of equations

[tex]x + y = 1[/tex]

⇒[tex]y = -x+1..(i)[/tex]

and

[tex]3y = -3x + 3[/tex]

⇒[tex]y = -x + 1..(ii)[/tex]

From equation (i) and (ii) we can see that there is no any intercept difference for the given system of equation. They have same slope and same intercept.

Therefore, the given system of linear equations coincide to each other, so they have infinitely many solutions.

Interquartile range

Step-by-step explanation:

In descriptive statistics, the interquartile range, also called the midspread or middle 50%, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q₃ − Q₁.

Hey there!

Let's start by making an equation to represent this.

500 - 3a = 266

Reduced by is the same as subtracting, and a represents age.

Subtract 500 from both sides.

-3a = -234

Divide each side by -3.

a = 78

Check.

500 - 3(78) = 266

500 - 234 = 266

266 = 266

You are 78 years old.

Hope this helps!

Answer: Age=78

Step-by-step explanation:

500-(3xAge)=266

500-266=3xAge

Answer:

2,400 cm²

Step-by-step explanation:

You can solve for x because you know that 40cm=x²+4cm:

36 cm = x²

x = 6cm.

Therefore the width is 2(6)²-12, which is 60cm.

So the area is 40 cm x 60 cm, which is 2,400 cm².

Answer:

8.54

Step-by-step explanation:

To find the distance between 2 points

d = sqrt( y2-y1)^2 + (x2-x1)^2)

where (x1,y1) and (x2,y2) are the two points

d = sqrt((5--3)^2+ (-1--4)^2)

  = sqrt((5+3)^2+ (-1+4)^2)

  =  sqrt((8)^2+ (3)^2)

   = sqrt(64+ 9)

    =sqrt (73)

Final answer:

Squaring a negative number in mathematics always results in a positive number due to the rule that the product of two negative numbers is positive. Complex numbers introduce the concept of imaginary units, allowing for square roots of negative numbers like the square roots of -1, which are i and -i.

Explanation:

Understanding the Square of a Negative Number

When you square a negative number, the result is positive. This is because according to the rules of multiplication, the product of two negative numbers is positive. For example, the square of -4 is (-4) x (-4), which equals 16. Hence, squaring a negative number always yields a positive result.

Complex Numbers and the Imaginary Unit

In mathematics, we also encounter situations where we need to consider the square of a number that is not positive. This is particularly relevant in the field of complex numbers. Complex numbers include the imaginary unit i, which is defined such that i² = -1. Complex numbers allow for the square roots of negative numbers to exist; for instance, the square roots of -1 are i and -i.

The Significance of the Square of a Negative Number

The concept of squaring a negative number and the resultant positive number is utilized in various branches of mathematics and physics. For instance, in spacetime geometry applied in physics, squaring a negative number can relate to intervals or measurements that factor into theories of relativity.

Or make it into an improper fraction -1 5/12 is also -17/12

17+7= 24

-24/12 = -2

Answer:

-2

Step-by-step explanation:

You need to understand two things about this subtraction. One thing is subtracting from a negative number. The other thing is doing an operation with mixed numerals.

Let's start with subtracting from a negative number.

To subtract, you add the opposite (also called the additive inverse). For example, 4 - 2 is the same as 4 + (-2). In other words, to subtract 2 from 4, you add the opposite of 2 to 4. Now you need to rules of addition of signed numbers.

Let's look at your problem.

-1 5/12 - 7/12

You are subtracting 7/12 from the negative mixed numeral -1 5/12.

Change the subtraction into an addition of the reciprocal. The opposite of 7/12 is -7/12, so to subtract 7/12, you add -7/12.

-1 5/12 - 7/12 =

= -1 5/12 + (-7/12)

Now you are adding two negative numbers.

To add two negative numbers, add their absolute values (meaning ignore the negative signs, just add the numbers), and then the answer is negative.

You need to add

1 5/12 + 7/12

Add the fractional parts: 5/12 + 7/12 = 12/12 = 1

1 5/12 + 7/12 = 1 + 12/12 = 1 + 1 = 2

Now that we added the absolute values, and we have a sum of 2, the final answer for the original problem is -2 since we were adding two negative numbers.

keeping in mind that two years is 24 months, and we know that cyclically it's losing 25% every 6 months.

Final answer:

The formula for calculating annual insurance premiums is based on several factors, including historical data, statistical analysis, and risk assessment.

Explanation:

The formula for calculating annual insurance premiums is based on several factors. Insurance companies use a combination of historical data, statistical analysis, and risk assessment to determine the premium amount. The general formula for calculating insurance premiums is:

Premium = (Average Person's Claims + Costs of Running the Company + Firm's Profits) / Number of Insured Individuals

For example, if there are 100 drivers and the insurance company needs to collect $186,000 to cover the costs of accidents, each driver would pay a premium of $1,860 per year.

The formula for calculating annual insurance premiums is Annual Premium = Base Rate [tex]\times[/tex] Coverage Amount [tex]\times[/tex] Adjustment Factors.

The formula for calculating annual insurance premiums is not a one-size-fits-all equation because it depends on various factors such as the type of insurance, the coverage amount, the deductible, the policyholder's risk profile, and other personal and policy-specific details.

However, a general form of the formula that can be used as a starting point is:

[tex]\[ \text{Annual Premium} = \text{Base Rate} \times \text{Coverage Amount} \times \text{Adjustment Factors} \][/tex]

Here, the base rate is the initial cost of insurance per unit of coverage, which is determined by the insurer based on the type of insurance and the average risk associated with it.

The coverage amount is the total amount of coverage the policyholder is purchasing. Adjustment factors are multipliers that reflect the policyholder's individual risk factors, such as age, health, driving record, credit score, etc.

Add the two angles you already know (for example, 50 and 45), then, with the sum of the two angles (95), subtract it from 180 (180-95) and there's your answer. How do I find the third angle of a triangle if the two known angles are 35 and 40?

The measure of any exterior angle of a triangle is equal to the sum of the measures of its two interior opposite angles. The sum of the three angles of a triangle is 180°. ... The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.

all i got (:

Answer:

The largest angle has a measure of 82 degrees.  

Step-by-step explanation:

Since the two angles are equal they represent x. Then the largest angle is 33 degrees more so that is represented as x+33. Then you get your equation: 3x+33=180(because each triangle has 180 degrees). Subtract 33 from both sides to get x by itself and you get 3x=147. Then to simplify divide 3 from both sides and you get 49 degrees for x. Since it says in the beginning that the largest angle is the value of x+33 we know that the largest angle is 82 degrees.
