What is the equation of the line passing through the points (-4,3) and (2,7)?

Answers

Answer:

[tex]y = \frac{2}{3} x + \frac{17}{3}[/tex]

Step-by-step explanation:

First, find the slope of the line:

The formula for finding the slope is: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Plug in the points:

[tex]\frac{7 - 3}{2 - (-4)}[/tex] = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]

So now the equation is y = [tex]\frac{2}{3}[/tex]x + b

Now solve for b by plugging in one of the points:

(2,7)

y = [tex]\frac{2}{3}[/tex]x + b

7 = [tex]\frac{2}{3}[/tex]2 + b

7 = [tex]\frac{4}{3}[/tex] + b

b = [tex]\frac{17}{3}[/tex]

So the equation will be [tex]y = \frac{2}{3} x + \frac{17}{3}[/tex]

What happens to the mean of the data set {2, 4, 5, 6, 8, 2, 5, 6} if the number 7 is added to the data set?

Answers

Answer:

It increases

Step-by-step explanation:

The mean of the given data set of 8 values is 4.75 ([tex]\frac{2+4+5+6+8+2+5+6}{8}[/tex])

Adding 7 into the data set also increase the number of data points to 9, so the mean becomes:[tex]\frac{2+4+5+6+8+2+5+6+7}{9}[/tex], which is equal to 5

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (-8,7) and (4,3)

Answers

First let’s find the gradient of the perpendicular bisector.

If the gradient of the line segment is m, then the gradient of its perpendicular bisector is -1/m.

Gradient of line= (y2-y1)/(x2-x1) =
(3-7)/(4- -8) = (-4/12) = -1/3

Therefore the gradient of the perpendicular bisector is 3

The perpendicular bisector will pass through the midpoint of line segment.

Midpoint of line= ((x1+x2)/2 , (y1+y2)/2)
=( (-8+4)/2 , (7+3)/2) = (-2,5)

Equation of perpendicular bisector : y=mx + c.

We know m is 3

So we have:

y=3x+c

The bisector passes through (-2,5). Replace in equation to find c.

5 = 3(-2) + c

5 = -6 + c
c = 5+6 = 11

So equation if bisector is y = 3x + 11

John takes out a loan for $ 12 , 000 at a simple interest rate of 4.5 % to be paid back in 36 monthly installments. What is the amount of the monthly payments?

Answers

Answer: $378.33

Step-by-step explanation:

First we calculate the Simple interest which will be:

= 12000 × 4.5% × 3

= $1620

Total amount to be paid = $12000 + $1620 = $13620

Since there are 36 monthly installments, the amount of the monthly payments would be:

= $13620 / 36

= $378.33

Marcus and Lara each have the same number of songs on their ipods. Marcus has 10x + 8 songs and Lara has
15x - 92 songs. What is x?

Answers

Answer:

The value of x is 20.

Step-by-step explanation:

Given that

Number of songs Marcus has = 10x+8

Number of songs Lara has = 15x-92

It is also given that they have the same number of songs that means both the expressions should be equal.

Putting both equal

[tex]10x+8 = 15x-92[/tex]

This is a linear equation in one variable which can be solved using properties of equality

Subtracting 10 from both sides

[tex]10x+8-10x = 15x-92-10x\\8 = 5x-92[/tex]

Adding 92 on both sides

[tex]8+92 = 5x-92+92\\100 = 5x[/tex]

Dividing both sides by 5

[tex]\frac{5x}{5} = \frac{100}{5}\\x = 20[/tex]

Hence,

The value of x is 20.

what fraction is equivalent to 4 12?

Answers

Answer:

1/3

Step-by-step explanation:

1/3, 2/6, 3/9, 4/12.

are equivalent fractions. Equivalent fraction of a given fraction is got by multiplying or dividing its numerator and denominator by the same whole number.

The given fraction 4/12 is equivalent to 1/3 which means that both fractions represent the same value.

To find a fraction equivalent to 4/12, we need to simplify it by reducing the numerator and denominator to their lowest terms.

In this case, the GCD of 4 and 12 is 4. When we divide both the numerator and denominator by 4, we get:

4/12 = (4 ÷ 4) / (12 ÷ 4)

= 1/3

Therefore, 4/12 is equivalent to 1/3.

This means that both fractions represent the same value, but the fraction 1/3 is in its simplest form, where the numerator and denominator have no common factors other than 1.
