Answer:

x = 6

Step-by-step explanation:

Given equation,

→ 6x - 16 = 20

Now the value of x will be,

                       [tex]\boxed {\frac{x-x_1}{x_2-x_1}=\frac{y-y_1}{y_2-y_1} }[/tex]

Line m: (-3,2)  (3,6)

[tex]\displaystyle\\\frac{x-(-3)}{3-(-3)} =\frac{y-2}{6-2} \\\\\frac{x+3}{3+3} =\frac{y-2}{4} \\\\\frac{x+3}{6}=\frac{y-2}{4}[/tex]

Multiply both parts of the equation by 4:

[tex]\displaystyle\\\frac{x+3}{6}(4)=y-2\\\\\frac{2}{3} (x+3)=y-2\\\\\frac{2}{3}x+2=y-2\\\\\frac{2}{3}x+2+2=y-2+2\\\\\frac{2}{3}x+4=y\\\\Thus,\ y=\frac{2}{3} x+4\\\\Hence,\ m_m=\frac{2}{3}[/tex]

Line n: (-5,-5)  (5,1)

x₁=-5   x₂=5   y₁=-5   y₂=1

[tex]\displaystyle\\\frac{x-(-5)}{5-(-5)}=\frac{y-(-5)}{1-(-5)} \\\\\frac{x+5}{5+5}=\frac{y+5}{1+5} \\\\\frac{x+6}{10}=\frac{y+5}{6}[/tex]

Multiply both parts of the equation by 6:

[tex]\displaystyle\\\frac{3}{5}( x+5)=y+5\\\\\frac{3}{5} x+3 =y+5\\\\\frac{3}{5} x+3-5=y+5-5\\\\\frac{3}{5} x-2=y\\\\Thus,\ y=\frac{3}{5}x-2\\\\Hence,\ m_n=\frac{3}{5}[/tex]

Line p: (3,-4)  (-3,6)

[tex]\displaystyle\\\frac{x-3}{-3-3} =\frac{y-6}{6-(-4)} \\\\\frac{x-3}{-6} =\frac{y-6}{6+4} \\\\\frac{x-3}{-6}=\frac{y-6}{10} \\[/tex]

Multiply both parts of the equation by 10:

[tex]\displaystyle\\-\frac{5}{3} x+5=y-6\\\\-\frac{5}{3} x+5+6=y-6+6\\\\-\frac{5}{3} x+11=y\\Thus,\ y=-\frac{5}{3}x+11 \\\\Hence,\ m_p=-\frac{5}{3}[/tex]

[tex]n \bot p[/tex]

Answer:

5) No the lines are not parallel because in order for this to be true, the slopes have to be equal. Line m has a slope of 2/3 and line n has a slope of 3/5. Both slopes are not equal so it is not parallel

6) No, m is not congruent to p

7) No, n is not congruent to p

(Is there any chance that you meant to say perpendicular instead of "congruent"?)

Step-by-step explanation:

For two lines to be parallel the slopes have to be equal

See attached to see the rise over run

line m: 2/3

line n: 3/5

The slopes are not equal so the lines are not parallel.

Slope of Parallel line is 3/4

Slope of Perpendicular line is -4/3

What is Slope of Line?

The slope of a line indicates its steepness. Slope is computed mathematically as "rise over run" (change in y divided by change in x).

Solution:

General Form of Line: y = mx + c

here, m is the slope

4y = 3x + 6

y = 3/4x + 3/2

Parallel Line have the same Slope = 3/4

The least polynomial with degree 3 is equal to f(x) = x³ - (8 / 7) · x² + 4 · x - 32 / 7.

In this problem we need to determine the least polynomial such that its degree is 3 and - i 2 and 8 / 7 are roots of the resulting expression. By quadratic formula, the roots - i 2 is along with its conjugate i 2 to obtain a quadratic equation with real coefficients. The factor form of the cubic polynomial is:

f(x) = a · (x - r₁) · (x - r₂) · (x - r₃)

Where:

And we must determine the standard form of the polynomial by means of algebra properties. This form is shown below:

f(x) = a · x³ + b · x² + c · x + d

Where a, b, c, d are real coefficients.

First, write the polynomial in factor form: (a = 1)

f(x) = (x - 8 / 7) · (x + i 2) · (x - i 2)

f(x) = (x - 8 / 7) · (x² + 4)

f(x) = x³ - (8 / 7) · x² + 4 · x - 32 / 7

In 2000, the population of the state was 23.1 million and the population of the state reach 28.3 million in 2013

From the question, we have the following parameters that can be used in our computation:

A=23.1 е⁰⁰¹⁵²⁺

Also from the question, we have

The variable t represents the number of years after 2000.

This means that

t = Current year - 2000

Substitute the known values in the above equation, so, we have the following representation

t = 2000 - 2000

Evaluate

t = 0

So, we have

A=23.1 е⁰⁰¹⁵² ˣ ⁰

Evaluate the above equation

A = 23.1

Here, we have

A = 28.3

Substitute the known values in the above equation, so, we have the following representation

23.1 е⁰⁰¹⁵²⁺ = 28.3

Divide both sides by 23.1

е⁰⁰¹⁵²⁺ = 1.22510822511

Take the natural logarithm of both sides

0.0152t = 0.203

So, we have

t = 0.203/0.0152

Evaluate

t = 13

So, the year is

Year = 2000 + 13

Year = 2013

This means that the population of the state reach 28.3 million in 2013

After the markup, the selling price of the item will be $39.

We know that a store owner decides to mark up all items by 30%, so basically we need to increase all the costs by 30%.

If the original cost is C, then the cost after the mark up will be:

P = C*(1 + 30%/100%)

P = C*(1 + 0.3)

P = C*(1.3)

In this case, we want to find the selling price P for an object whose original cost C is $30, then we can replace C in the equation above so we get:

P = $30*1.3 = $39

The standard form equation for the line through the points (3,-4) and (6,-2) is  -2/3 x + y = 4.

What is the equation of the line passing through the two-point?

To find the equation for the line through two points we can use the formula:

y - y1 = m(x - x1)

where (x1, y1) is one of the points, and m is the slope of the line. The slope of the line is equal to the change in y over the change in x, which can be calculated as:

m = (y2 - y1) / (x2 - x1)

where (x2, y2) is the other point.

Substituting the given points and the formula for the slope into the formula for the equation of the line, we get:

y - (-4) = ((-2) - (-4)) / (6 - 3) (x - 3)

This simplifies to:

y + 4 = -2/3 (x - 3)

To write the equation in standard form, we can distribute the -2/3 and then rearrange the terms:

-2/3 x + y = 4

Hence, the standard form equation for the line through the points (3,-4) and (6,-2) is  -2/3 x + y = 4

Answer:

$5000

Step-by-step explanation:

Let x represent the amount invested at 6% interest. Then 7000-x is the amount invested at 7% interest

6% interest = 6/100 = 0.06 in decimal

7% interest = 7/100 = 0.07

Interest earned from depositing x dollars at 6% = 0.06x

Interest earned from depositing 7000-x at 7% = 0.07(7000-x)

Total interest earned would be
0.06x + 0.07(7000-x)

Since this must be at least $440 we get the equation interest as

0.06x + 0.07(7000-x) = 440

Simplifying
0.06x + 0.07 x 7000 - 0.07x = 440

0.06x + 490 -0.07x = 440

-0.01x = 440 - 490

-0.01x = -50

Multiply both sides by -1

==> 0.01x = 50

==> x = 50/0.01 = 5000

So max amount that can be invested at 6% interest = $5000

The freight train is 88.88 feet long.

Speed = Distance/Time

Distance = Speed X Time

Time = Distance / Speed

As the trains travel in opposite direction then

Relative speed = (42 + 18) = 60 Km/ hr

                                            = 60 x 5/18 = 300/ 18

                                             = 100/9 m/s

So, length of the freight train = 100/9 x 8

The estimate of the average height of all the trees having a trunk diameter of 7 inches is y = 18.1 feet. This is obtained by using the LSRL equation. Option A is the correct value.

The LSRL equation is defined as the Least squares regression line. This is the line that minimizes the variance. So, it is the best line of fit for a set of data points.

The equation is in the form of Y = a + bX

Here a is the intercept and b is the slope.

It is given that,

X is given as the diameter of a tree trunk in inches

Y is given as the tree height in feet

The given data points are:

X: 4, 2, 8, 6, 10, 6

Y: 8, 4, 18, 22, 30, 8

For these data points, the least squares regression line is given by the equation Y = - 3.6 + 3.1X

So, the estimate of the average height of all trees having a trunk diameter of 7 inches is

Y = - 3.6 + 3.1X ⇒ Y = -3.6 + 3.1 × 7

⇒ Y = -3.6 + 21.7

Ages of Tristan, Richard, and Pablo are in the order 6:7:4.

Detailed explanation:

Pablo is six years younger than Richard, seven years older than Tristan, and five years younger than Richard.

We can multiply the ratios of Pablo's age to Richard's age and Pablo's age to Tristan's age to determine the ratio of Tristan's age to Richard's age before determining the ratio of Tristan's age to Pablo's age.

These ratios add up to 6/7 * 5/4 = 30/28.

Pablo's age to Richard's age is 6:7, thus we may multiply this ratio by the age of Richard by Tristan's age to determine the age of Pablo, Richard, and Tristan.
