Is 5x 3y a linear equation in two variables?

Answers

Yes, 5x - 3y = 7 is a linear equation in two variables (x and y)

A linear equation in two variables is an equation in the form ax + by = c, where a, b, and c are real numbers and a and b are not both 0. In this equation, 5x 3y, the coefficients of the variables are 5 and 3, respectively, so a = 5 and b = 3. Therefore, 5x 3y is a linear equation in two variables.

A linear equation in two variables (x and y) is an equation that can be written in the form ax + by = c, where a and b are real numbers and a and b are not both 0. This means that any equation that has two variables with real coefficients will be a linear equation. For example, 5x 3y is a linear equation in two variables because the coefficients of the variables x and y are 5 and 3, respectively. Therefore, 5x 3y is a linear equation in two variables.

Six times the sum of a number and 25 is at least 30

Answers

Answer:

Step-by-step explanation:

Let the number be x then:.

6 * (x + 25) = 30

therefore,

x + 25 = 30 / 6

x + 25 = 5

x = 5 - 25 = -20

A "Pick 2" lottery game involves drawing 2 numbered balls from separate bins each containing balls labeled from 0 to 9. So there are 100 possible selections in total: 00, 01, 02, ..., 98, 99. Players can choose to play a "straight" bet, where the player wins if they choose both digits in the correct order. Since there are 100 possible selections, the probability a player wins a straight bet is 1/100. The lottery pays $50 on a successful $1 straight bet, so a player's net gain if they win this bet is $49. Let X represent a player's net gain on a $1 straight bet. Calculate the expected net gain E(X). Hint: The expected net gain can be negative. E(X) = dollars

Answers

Answer:

The probability of winning a straight bet is 1/100, and the payout is $50, so the expected value of a winning bet is (1/100) * $50 = $0.50.

The probability of losing a straight bet is 99/100, and the cost of the bet is $1, so the expected value of a losing bet is (99/100) * -$1 = -$0.99.

Therefore, the expected value of a straight bet is $0.50 - $0.99 = -$0.49.

De las soluciones de la siguiente ecuación: x2 + 8x − 30 = 18? Cual es el numero de mayor valor Entre.

Answers

Answer:

The correct answer is "x = 4" and "x = -12".

Step-by-step explanation:

The given equation is:

⇒  [tex]x^2+8x-30=18[/tex]

On subtracting "18" from both sides, we get

⇒  [tex]x^2+8x-30-18=18-18[/tex]

⇒  [tex]x^2+8x-48=0[/tex]

On applying factorization, we get

⇒  [tex]x^2+12x-4x-48=0[/tex]

On taking common, we get

⇒  [tex]x(x+12)-4(x+12)=0[/tex]  

⇒  [tex](x-4)(x+12)=0[/tex]

⇒                 [tex]x-4=0[/tex]

Answers

Answer: $52.57 for each basic yearbook and $153.5 for each deluxe yearbook

Step-by-step explanation:

First, do Mr. Boyer's class to find out how much each deluxe yearbook is:

2,763 ÷ 18 = $153.5

Then do, Mrs. Wu's class: First, multiply 153.5 by the 6 deluxe yearbooks ordered;

153.5 x 6 = 921

After, subtract 921 from 2,025:

2,025 - 921 = 1104

The remaining $1104 is the total cost of the 21 basic yearbooks ordered. Divide the total cost by the number of yearbooks ordered to find the unit price:

Is a log graph increasing or decreasing?

Answers

A log graph can be either increasing or decreasing, depending on the function or data being graphed.

A log graph is a type of graph that displays the data on a logarithmic scale. That is, the values of the data are represented on a logarithmic scale, rather than on a linear scale. This type of graph is useful for displaying data or functions that span a wide range of values over a large range of exponents. The direction of the graph depends on the data being graphed or the function being shown. If the values of the data or the function being graphed increase over time, then the graph will be increasing. Conversely, if the values of the data or the function being graphed decrease over time, then the graph will be decreasing.

1.The income of man increase in the ratio 7 : 8 . If the increase in his income is rs 4500 per month find his new income.

2.The ages of two sister are in the ratio 7 : 5 if the age of elder sister is 15 years 9 months, what is the age of younger sister.

Answers

The new income is new income.

Rs. 36000 per month. 6 years and 6 months.

What is the new income.?

Generally, To find the new income of the man, we can use the formula: New Income = Original Income + Increase in Income

Since the ratio of increase in income is 7:8, we can assume the original income to be 7x and the new income to be 8x.

The increase in income is given as Rs. 4500 per month, so we can set up the equation as:

8x = 7x + 4500

By solving for x, we get that

x = 4500.

Therefore, the new income of the man is

8x = 8 * 4500

= Rs. 36000 per month.

b)

The ages of the two sisters are in the ratio 7:5. If the elder sister is 15 years 9 months old, we can assume her age in months to be

15*12 + 9 = 189 months.

Let's assume x be the age of younger sister in months.

So, according to the ratio 7:5, we can set up the equation as:

x = (5/12)*189

By solving this equation we get

x= 78.75 months, which is roughly 6 years and 6 months.

Question content area top Part 1 Without using paper and​ pencil, how would you find the sum of 8.8 and 5.5 and ​?

Answers

The sum of 8.8 and 5.5 is 14.3

What is addition?

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

To find the sum of 8.8 and 5.5 without using pen and pencil:

First, we break the term in simple manner.

8.8 = 8 + 0.3 + 0.5

And 5.5 = 5 + 0.5

And now adding the terms one by one,

0.5 + 0.5 = 1.0

0.3 = 0.3

8 + 5 = 13

Addition,

13 + 1 + 0.3 = 14.3

Therefore, the value is 14.3

How do you find the y-intercept without a calculator?

Answers

In the equation y = mx + c if we substitute the value of x as zero we will get a point on the y axis given by y =(m × 0) + c ⇒ y = c. Therefore the point of the line on the y axis is (0, c) and so c is also called the y -intercept  of the line.

Now, According to the question:

i) from the general equation of line we know that any line can be represented in the form y = mx + c , where m is a constant and is called the slope of the line and c is also a constant and is the y-intercept.

ii) In the equation y = mx + c if we substitute the value of x as zero we will get a point on the y axis given by y =(m × 0) + c ⇒ y = c. Therefore the point of the line on the y axis is (0, c) and so c is also called the y intercept  of the line.

iii) If for example we have the line 3y = 6x + 12 then we first get this equation of the line to match the general form of the equation of the line, that is y = mx + c. Therefore dividing both the left and the right sides of the given equation of the line by 3 we get y = 2x + 4 which matches with the general form of the equation for line and we see that the slope of the given line is m = 2 and the y intercept is given by c = 4.
