The slope of the line is 7/3 the y-intercept is -3 and the function is y = 7/3x - 3.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -3 - 4 ) / ( 0 - 3 )

Slope = -7 / -3 = 7 / 3

The y-intercept will be,

y = mx + c

y = 7 / 3x + c

-3 = 0 + c

c = -3

The equation of the line will be,

y = mx + c

y = 7/3x - 3

Answer:

45%

Step-by-step explanation:

The value of percentage of the pizza did Lilly eat is,

⇒ 45%

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Lilly and Kornelia shared a whole pizza.

And, They shared a pizza in the ratio 9 : 11.

Now, We get;

The value of percentage of the pizza did Lilly eat is,

⇒ 9 / (9 + 11) x 100

⇒ 9/20 x 100

⇒ 9 × 5

⇒ 45%

Thus, The value of percentage of the pizza did Lilly eat is,

⇒ 45%

The gold, silver, and bronze in a ratio of 2 : 2 : 5 will be 4, gold, 4 silver and 10 bronzes.

Ratio in Mathematics simply demonstrates how many times one number can be able to fit into another number. It should be noted that ratios contrast two numbers by dividing them. In this case, A/B will be the formula if one is comparing one variable (A) to another variable (B).

In this situation, team wins 18 medals at a track meet. The medals are gold, silver, and bronze in a ratio of 2 : 2 : 5.

Gold = 2/9 × 18

= 4 gold's

Silver = 2/9 × 18

There are 3 medium pizza and 6 large pizza.

Let medium pizza = x

Let large pizza = y

Since she she places the order from Tony's pizza across the street, she learns that each medium pizza has 6 slices, and each large pizza has 8 slices and Ms. Johnson orders 9 total pizzas with a total of 66 slices

This will be:

x + y = 9 ..... i

6x + 8y = 66 ..... ii

From i, x = 9 - y

Put this into equation ii

6x + 8y = 66

6(9 - y) + 8y = 66.

54 - 6y + 8y = 66.

2y = 12

Divide

y = 12/2

y = 6.

Therefore there are 6 large pizzas

Medium pizza = 9 - 6 = 3

Its kind of simple really

so the answer is 57 bacteria per hour

Answer:

To put this equation in standard form, you need to complete the square for both the x's and the y's.

First, complete the square for the x's by adding and subtracting (16/2)^2 = 16^2/2^2 = 32/2 = 16.

4x² - 16x + 16 - 16 - 5y² - 30y - 9 = 0

4x² - 16x + 16 - 5y² - 30y - 9 = 0

Now, complete the square for the y's by adding and subtracting (30/2)^2 = 30^2/2^2 = 900/2 = 450.

4x² - 16x + 16 - 5y² - 30y + 450 - 450 - 9 = 0

4x² - 16x + 16 - 5(y² - 15y + 225) - 9 = 0

Now, you can simplify the expression inside the parentheses by completing the square for y.

4x² - 16x + 16 - 5(y - 15)^2 + 5*225 - 9 = 0

Now, divide everything by -5 to get the equation in standard form:

-4/5x² + 16/5x - 16/5 - (y - 15)^2 = 0

The standard form of the equation is:

(-4/5)x² + (16/5)x - 16/5 - (y - 15)^2 = 0

The Newton-Raphson method is a type of iterative method for solving non-linear equations.

The Newton-Raphson method is an iterative method for finding the roots of a non-linear equation. The basic idea is to start with an initial guess for the root, and then use the information from the derivative of the function to refine the guess in the direction of the root. This process is repeated until the guess is sufficiently close to the root.

The Newton-Raphson method is known to be very fast and efficient, but it does have some limitations. For example, it can only be used for functions that are differentiable, and it may not converge if the initial guess is not close enough to the root.

Answer:

Part 1: 10^2 = 3x + 4

part 2: x = 32

Answer:

y = 2x - 11

Step-by-step explanation:

In y = 2x - 7, the slope is 2.

A slope parallel to this would also be 2.

y = 2x + b

-1 = 2(5) + b

-1 = 10 + b

b = -11

y = 2x - 11

The scale factor of the dilation is one-fifth, two-fifths, five-halves, or 5.

The scale factor of a dilation describes the ratio of the lengths of corresponding sides of the image and the preimage. To calculate the scale factor, we must first identify the lengths of the preimage and the image. Let's say that the preimage has a length of 10 units, and the image has a length of 5 units. To calculate the scale factor, we divide the length of the image by the length of the preimage: 5/10 = 1/2.

This tells us that the scale factor of the dilation is 1/2, or one-half. To determine the scale factor in terms of a fraction with a denominator of five, we can multiply the numerator and denominator of the fraction by five, resulting in a scale factor of 2/5, or two-fifths. To express the scale factor as a fraction with a numerator of five, we can multiply the numerator and denominator of the fraction by two, resulting in a scale factor of 5/2, or five-halves. Finally, to express the scale factor as a decimal, we can divide the numerator by the denominator, resulting in a scale factor of 2.5, or 5.

The statement that is NOT true is: "The priors used in the Bayesian approach to variant calling do not influence which genotype you infer from your data."

Bayesian approach is a statistical method that uses prior probabilities to update the probability of an event based on new data. In variant calling, the prior probabilities are used to estimate the likelihood of observing a variant at a certain position in the genome. The priors are chosen based on the prior knowledge of the biology of the organism and the specific variant being called. The priors used in the Bayesian approach will influence which genotype is inferred from the data, as the prior probabilities can bias the variant calling towards certain genotypes.

There is no solution existing for the given equation 3z + 13 =  3( z + 6 )+ 1.

Solving the equation,

3z + 13 =  3( z + 6 )+ 1

 3z + 13 = 3z + 18 + 1

 3z + 13 = 3z + 19

Shifting variables to one side of the equation and constants to the other side of the equation so that equation could be solved further:

Now

 3z - 3z  = 19 - 13

  0 =  6,           revealing that no solution exists for this equation.

Thus, the result shows that the given equation has no solution because 3z cancels out 3z making both sides unequal.
