The answers to each part is mentioned below.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given are the questions as mentioned.

Direct variation of {y} with {x} means that as {x} increases, the value of {y} increases uniformly with it. Mathematically -

{K} = y/x = constant

Scale factor {K} is a dimensionless value that indicates the constant ratio value indicating direct variation.

{ 1 } -

The variables y and x have a proportional relationship.Also y = 15 when x = 3.We can write for proportional relationship as : 15/3 = 4/x

{x} = (4 x 3)/15 = 4/5

{x} = 4/5

{ 2 } -

The variables y and x have a proportional relationship.Also y = 9 when x = 2.We can write for proportional relationship as : 9/2 = y/3

{y} = (9 x 3)/2 = 27/2 = 13.5

{y} = 13.5

{ 3 } -

An equation representing a proportional relationship is of the form -

y = mx + c

So all the equations given represent proportional relationship.

Therefore, the answers to each part is mentioned above.

Of the 2,374 pieces produced by a particular machine, 27 were defective. What
percent were defective? Round to the nearest hundredth of a percent.

Answers

Answer:

1.14%

Step by step explanation

Step one:

The total pieced produces is 2374

total defective is 27

to find the percentage of the defective pieces, we would need to divide the total pieces of the defective by the total number of pieces produced by the machine and multiply the result by 100

Step two

% defecive= (27/2374)*100

% defecive= 0.0113*100

% defecive= 1.137%

To the nearest hundredth of a percent 1.14%

Write the equation y = 4x – 20 in Standard Form (AX + By = C) with integer coefficients

HELP ASAP PLEASE

Answers

Answer: 4x - y = 20

=============================================

Work Shown:

y = 4x - 20

4x - 20 = y ...... swap both sides

4x = y + 20 ..... adding 20 to both sides

4x - y = 20 .... subtracting y from both sides

The equation is now in standard form (Ax+By = C) where,

A = 4B = -1C = 20

Israel planted 4 tomato seeds in his garden. Then he planted flower seeds in each of his three neighbor's gardens. Which expression represents the number of seeds Israel planted?
A. 4s + 3
B. 4 + 3s
C. 4 – 3s
D. 3s – 4

Answers

Answer:

B. 4+3s

Step-by-step explanation:

The expression that represents the number of seeds that has been planted by Israel is 4 + 3s. Hence, Option B is correct.

What is an expression?

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression in mathematics.

Mathematical symbols can represent variables, operations, functions, brackets, punctuation, and grouping to help specify the logical syntax and order of operations.

But in contemporary mathematics, and particularly in computer algebra, formulae are seen as expressions that can be evaluated as true or false, depending on the values given to the variables present in the expressions.

In the garden, Israel sowed 4 tomato seeds. Then Israel scattered flower seeds throughout the gardens of the three neighbors. Here neighbors will be denoted as x. For this the most suitable expression will be 4 + 3s.

Therefore, Option B is correct.

for two complex numbers z and w, which diagram shows the geometric representation of zw

Answers

Answer:

The answer is the last one, D, pictured above on the question, I took the test and it showed it was the right one

Step-by-step explanation:

The geometric expression of two complex number is the magnitude r₁*r₂ and the phase is θ₁ + θ₂.

What is complex number?

The complex number is" the combination of real numbers and an imaginary number. The complex number is of the form a + i b".

According to the question,

z, w are the two complex numbers. The distance from its point in the complex plane to the origin (0,0) and the angle formed by the line segment from the origin to the point and the positive half of the x-axis.

The distance or 'magnitude' to the origin is denoted as 'r' and the angle or 'phase' formed denoted as 'θ'. The distance to the origin is called 'magnitude'.

The parameter 'r' and 'θ' related to 'a' along x-axis and 'b' along y-axis.

Euclidean distance formula applying Pythagorean theorem we have

r = [tex]\sqrt{a^2+b^2}[/tex].

The sine angle is defined to the ratio y-coordinate 'b' to length 'r' and the cosine angle is defined to the ratio x-coordinate 'a' to length 'r'.

sin θ = [tex]\frac{b}{r}[/tex] and cos θ = [tex]\frac{a}{r}[/tex].

b = r sin θ; a = r cosθ

When multiplying two complex numbers we by multiplying magnitude together and add two phase. when divide two complex number by dividing the magnitude correspondingly and subtracting the phase from the numerator and the denominator.

Then we have product complex number to the magnitude r₁ and phase θ₁

with a complex number to the magnitude r₂ and the phase θ₂ which gives the complex number with magnitude r₁ * r₂ and θ₁ + θ₂.

Hence, the geometric representation of z w is with magnitude r₁*r₂ and phase is θ₁ + θ₂.

PLEASE HELP!!!Which statement is true? Select all that apply.

The relationship is proportional.

The slope is -6.

The slope is negative.

The y-intercept is -3.

The equation of the line is y = -3x

Answers

Answer:

"The relationship is proportional."

"The relationship is proportional."

"The equation of the line is y = -3x"

Step-by-step explanation:

First, a proportional relationship can be written as:

y = k*x

where k is called the constant of proportionality. (or the slope)

You can see that if we take x = 0, we have

y = k*0 = 0

Then this type of line always passes through the point (0, 0).

And in the graph you can see that this line does that, then:

"The relationship is proportional." is true.

We also can see that as x increases, the value of y decreases, this must imply that k is a negative number, then:

"The slope is negative." is true.

To find the value of the slope, we can take two points that belong to the line.

I will choose:

(0, 0) and (2, -6)

For the slope, we just take the quotient between:

Δy = -6 - 0 = -6 (the difference in the y-components)

Δx = 2 - 0 = 2 (the difference in the x-components)

the slope is:

k = Δy/Δx = -6/2 = -3

Then the slope is -3, and we can write the equation as:

y = -3*x

Then:

"The equation of the line is y = -3x" is true.
