The equation of the given line in the diagram above is expressed as: b. y = 2/3x.

For a line that passes through the origin (0, 0) of a graph, the equation that represents the line can be written in slope-intercept form as y = mx, where the slope of the line is represented as m.

The y-intercept of this type of line is zero, that is why we have the equation expressed as y = mx. Where the y-intercept is not equal to zero, the equation of the line would be expressed as y = mx + b, where b is the y-intercept and m is the slope of the line.

Find the slope of the line using two points on the line, (0, 0) and (3, 2):

Slope of the line (m) = (2 - 0)/(3 - 0)

Slope of the line (m) = 2/3.

To write the equation of the line, substitute m = 2/3 into y = mx:

y = 2/3x.

The equation is: B. y = 2/3x.

Answer:

E. [tex] a = 5-2b [/tex]

Step-by-step explanation:

how to find the value of a, we need to subtract 2b from both side to single out the variable

a + 2b = 5

subtract 2b from both sides

a + 2b - 2b = 5 - 2b

a = 5 - 2b

Therefore, Option E is the correct answer

Tiana is more likely to win the competition as she took less time to type the same number of words, She will type more during the competition as her typing speed is more.

Since the upcoming match is next week, it is very important to practice before the actual match, hence, both participants were practicing to their best.

It is more likely that the person who does their best while practicing is more likely to perform better in the actual competition.

The competition will have the same amount of time to type, hence who will take less time to type more words will ultimately win the match.

Each bracelet price is $4 if Hyo-Jin makes bracelets and sells them on an online craft website. Last month, she sold 6 bracelets.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The equation is in the word:

With the commission of $1.25 for each bracelet sold, Hyo-Jin made a total of $16.50.

Let x be the cost of each bracelet:

Total earning = 16.50 + 7.50

Total earning = 24

Each bracelet price x = 24/6 = $4

Thus, each bracelet price is $4 if Hyo-Jin makes bracelets and sells them on an online craft website. Last month, she sold 6 bracelets.

The question is incomplete.

The probability that at least one of them is not interested in investment banking is 13/14.

It is a branch of mathematics. The possibility of the outcome of any random event is termed as probability. The range of the probability must be between o to 1. Here o indicates impossibility of an event and 1 indicates certainty. Probability can be expressed in proportions. Probability deals in finding the occurrence of an event.

Probability of the first person who is not interested in investment banking is 6/21

Probability of the second person who is not interested in investment banking and also first person was not interested then it is taken as 5/20.

probability that at least one is not interested in investment banking

=1- The probability that neither one of them is not interested in investment banking

=1-((6/21)×(5/20)

=13/14

Therefore, the probability that at least one of them is not interested in investment banking is 13/14.

The statement that does not describe the data set 6, 8, 8, 10, 10, 10, 10, 12, 12, 14 is:

(C) The range of the data set is 15.

Consider the data set,

6, 8, 8, 10, 10, 10, 10, 12, 12, 14

The mean of the data set will be:

mean = ( 6 + 8 + 8 + 10 + 10 + 10 + 10 + 12 + 12 + 14 )/ 10

mean = 100/10

mean = 10

The data set in ascending order are:

6, 8, 8, 10, 10, 10, 10, 12, 12, 14

As the number of terms is even. Therefore, the median will be the sum of two middle numbers divided by 2.

So,

Median = ( 10 + 10 )/2 = 20/2 = 10

The mode of a data set is the maximum number of times a number appears in the data set.

Therefore, the mode of the data set is 10.

The range of the data set is the difference between the highest and the lowest number in the data set.

Range = 14 - 6 = 12

The data set is a symmetric distribution if the mean, median, and mode all fall at the same point.

As the mean, median, and mode are 10, 10, and 10 respectively. Hence, the data set is symmetric.

Hence, statements (A), (B), and (D) are true.

The amount Bennet will have when he turns 18 will be equal to $3020.

Compound interest is the type of interest charged by banks or institutions on individuals in which the amount after 1 year becomes the principle for the next year. It can be calculated daily, monthly or yearly etc. The formula for compound interest compounded daily will be

A = P(1 + r/n) ^nt, where A is the amount, P is the principle, which is equal to $2000, r is rate of interest which is 3.2% or 0.032, n is compounding frequency which is equal to 365 and t is the time which is equal to 13 years. Now, the amount will be

A = 2000(1 + 0.032/365) ^365×13

Answer:

x=-6,8

Step-by-step explanation:

First, let's observe our equation, there is an absolute value (|x|) that means 'x' will have two answers most likely positive and negative.

First we will take off the lines.

now we have

2-2x=14

next minus 2 out of both side of the equation

2 - 2 -2x = 14- 2

-2x =12

now we will divide -2 from both side of the equation

[tex] \frac{ - 2x = 12}{ - 2} [/tex]

we will cancel out - 2

[tex]\frac{x = - 6}{1} [/tex]

x= -6

We aren't done yet since this is an absolute value we have to convert the sum of the equation ( 14) to negatives now which will be in this case (-14)

your new equation will look like this

2-2x= -14

next minus 2 out of both side of the equation

2 - 2 -2x = -14- 2

-2x = - 16

now we will divide -2 from both side of the equation

[tex] \frac{ - 2x = - 16}{ - 2} [/tex]

we will cancel out - 2

[tex] \frac{x = 8}{1} [/tex]

x = 8

x = -6

2 - 2x = 14

2 - 2(-6) = 14.

2 + 12 = 14✓.

x= 8

2 - 2x = -14

2 - 2 (8) = -14

2 - 16 = -14✓

Considering the expression of a line, the slope of the line that passes through the pair of points (3, -4) and (-2,0) is -1.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope of the line can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

In this case, being (x₁, y₁)= (3, -4) and (x₂, y₂)= (-1, 0), the slope m can be calculated as:

m= (0 - (-4))÷ (-1 -3)

m= (0 +4)÷ (-1 -3)

m= 4÷ (-4)

m= -1

Finally, the slope of the line is -1.

The route from her house to school consists of two straight legs.

She drives straight for 5 miles, and then she makes a right turn of 45 degrees and drives another 9 miles.

⇒ BC = 5 miles and AC = 9 miles

We need to find the distance from Jessica's school to her house in miles.

i.e., we need to find AB

Using Pythagoras theorem,

AC² = AB² + BC²

9² = AB² + 5²

AB = √(81 - 25)

AB = 7.48

The correct point slope form is  y - 1 = 2 ( x - 9).

What is the point slope form?

The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables. Depending on the facts at hand, there are different ways to find a line's equation.

The partial products of 242 × 28 are 4,000, 1,600, 840 and 336 and the value of 242 × 28 exists 6,776.

To estimate the partial product of two numbers, first, we write both numbers as the sum of the place values of the digits. Multiply each place value of the first number by the place value of the second number.

Given: 242 × 28

(200 + 42) × (20 + 8)

(200 × 20) + (200 × 8) + (42 × 20) + (42 × 8)

simplifying the above equation, we get

200 × 20 = 4,000

200 × 8 = 1,600

42 × 20 = 840

42 × 8 = 336

The above values are the partial product.

4,000 + 1,600 + 840 + 336 = 6,776

Therefore, the partial products of 242 × 28 are 4,000, 1,600, 840 and 336 and the value of 242 × 28 exists 6,776.

The inequality expression given as |2x - 6 | < 0  has a solution of x > 3

From the question, the inequality is given as

|2x-6|<0

This gives

|2x - 6 | < 0

Remove the absolute bracket

So, we have the following representation

2x - 6 > 0

Add 6 to all sides of the inequality

So, we have

2x - 6 + 6 > 0 + 6

Evaluate the like terms

So, we have

2x > 6

Divide through by 2

x > 3

Hence, the solution to the expression is x > 3
