The graph of the linear function f(x) = 2 - 3x is a straight line attached below

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.

A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,

The function given y = 2 - 3x can be plotted on a graph using function table

When x = -3

f(-3) = 2 - 3(-3)

f(-3) = 11

when x = -2

f(-2) = 8

when x = - 1

f(-1) = 1

when x = 0

f(0) = 2

when x = 1

f(1) = -1

when x = 2

f(2) = -4

when x = 3

f(3) = - 7

We can use this data and plot a graph.

Answer:

3x + 5 =3x + 8

Step-by-step explanation:

3x - 3x = 8-5

x = 3

Step-by-step explanation:

we have to soft the ones that have no solutions.

3x + 5 = 3x + 8

5 = 8

that is never true, and therefore there is no solution.

3(x + 5) = 3x + 15

3x + 15 = 3x + 15

that is always true, and it has therefore infinitely many solutions.

2(x + 1) = 2x + 1

2x + 2 = 2x + 1

2 = 1

this is never true, so, there is no solution.

2x + 1 = 2x + 1

this is always true, so this has infinitely many solutions.

According one-way ANOVA, the test is false.

In the given question,

When comparing three or more populations means within a set of quantitative data that is categorized according to one​ factor/treatment, a​ one-way ANOVA is appropriate. It is also appropriate in this​ situation, however, to compare two means at a time using multiple independent two sample​ t-tests. We have to check whether this is true or​ false.

We firstly learn about one-way ANOVA

"One-Way ANOVA, also known as "analysis of variance," examines the means of two or more independent groups to see if there is statistical support for the notion that the related population means are statistically substantially different."

According to the given method it is inappropriate to compare two means at a time using multiple independent two sample​ t-tests. It will create multiple testing problem and error.

So using one way ANOVA test when comparing three or more populations means within a set of quantitative data that is categorized according to one​ factor/treatment and compare two means at a time using multiple independent two sample​ t-tests is false.

Answer:

x = 7/2

Step-by-step explanation:

-28/5 x -2/5 = -2x -4x + 1

-28/5 x -2/5 = -6x + 1

-28 x -2 = -30x + 5

30 x -28 x = 5 + 2

2x = 7

2/2 x = 7/2

x = 7/2

Answer:

(7/2)

Step-by-step explanation:

I'll rewrite "4/5(-7x-1/2)=-2x-(4x-1)" to (4/5)(-7x-1/2)=-2x-(4x-1) to clarify the fraction (I am not interpreting it as 4/(5(-7x-12))).  [The five is not part of the denominator in my rewrite]

(4/5)(-7x-1/2)=-2x-(4x-1)

(-28x-2)= 5*((-6x+1)) [multiply the numerator by 4 on the left side, and multiply both sides by 5]

-28x-2= -30x + 5   [Combine like terms]

2x   = 7          [Put like terms together by adding 30x and +2 to both sides]

x = (7/2)  This satidfies the equation.

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

Step-by-step explanation:

[tex]\frac{7}{b^2+5b+4}[/tex] × [tex]\frac{b^2+8b+7}{b+7}[/tex] ← factor quadratics on numerator/ denominator

= [tex]\frac{7}{(b+1)(b+4)}[/tex] × [tex]\frac{(b+1)(b+7)}{b+7}[/tex]

cancel factors (b+ 1) and (b + 7) on numerator/ denominator

= [tex]\frac{7}{b+4}[/tex] × 1

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

Answer: y = 2x - 13

Step-by-step explanation:

y=mx + b

[tex]m= \frac{-7-(-1)}{3-6}[/tex]

   [tex]= \frac{-6}{-3}[/tex]

[tex]m = 2[/tex]

y = 2x + b

(6, -1) <-- use to find "b" by substituting either one of the coordinates

-1 = 2(6) + b

-1 = 12 + b

-13 = b

y = 2x - 13

The point on the y-axis is (0,1) such that the distance is minimum.

Let the coordinate of the point W be (0,a)

We know that the distance from any point on the coordinate place is calculated using the distance formula.

Now let us calculate the distance of VW = √[(2-0)²+(3-a)²]

Distance XW = √[(-2-0)²+(-1-a)²]

Now the sum of the distances is given by:

VW + XW

=√[(-2-0)²+(-1-a)²] + √[(2-0)²+(3-a)²]

This can be written in the form of a function in a such that:

f(a) = √a²+2a+5 + √a²-6a+25

Now we will differentiate with respect to a to get the required first degree

f'(a) = [tex]\frac{a+1}{\sqrt{a^2+3a+5}} + \frac{a-3}{\sqrt{a^2-6a+25}}[/tex]

Now at f'(a)=0

we get a=1.

Hence the required point on the y-axis that is at a minimum distance is (0,1) .

The 95% confidence interval estimate of the population mean is between $50,555.51 and $51.444.49.

Confidence interval is defined as the range of values where a parameter might fall at a given confidence level. It can be calculated using the formula below.

CI = μ ± z x (SD / √n)

where CI = confidence interval

μ = sample mean

z = found by using a z-score table

SD = sample standard deviation

n = sample size

At 95% confidence level, the area in each tail of the standard normal curve is 2.5, and the cumulative area up to the second tail is 97.5.

(100 - 95) / 2 = 2.5

100 - 2.5 = 97.5

Find 0.975 in the z-table to get the value of z.

At p = 0.95, z = 1.96

Plug in the values and solve for the confidence interval.

CI = μ ± z x (SD / √n)

CI = $51,000 ± 1.96 x ($1,200 / √28)

CI = $51,000 ± $444.49

CI = [$50,555.51, $51.444.49]

The answer is 47.

Step-by-step explanation:

To find the median, you need to write the numbers in order from least to greatest. However, that is already done.

Then, you need to count the numbers from the ends to the middle.

For example, if the numbers were 2, 4, 8, 9, and 10, you would do it like this (see the example below)

So, you would go from 32 to 45 and 72 to 63, and from 45 to 47 and 63 to 47.

This means that the median is 47.

The amount owed is $10865, based on the given parameters

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865

Hence, the value of the amount after 6 years is $10865

The intermediate step in the form (x + a)² =b as a result of completing the square for the given equation is (x - 6)² = 64

Given,

The equation  x² - 28 = 12x

We need to find the intermediate step in the form (x + a)² =b as a result of completing the square for the given equation

Equation; x² - 28 = 12x

Arrange the equation;

x² - 12x = 28

Take the coefficient of x

k = -12

Divide it by 2

k/2 = -6

Square both sides

(k/2)² = 36

Add 36 to both sides of x² - 12x = 28

x² - 12x + 36 = 28 + 36

To calculate the proportion of small and large boxes that were bought,

Let's assume the small boxes as 's' and the big boxes as '3s'.

∴ s(100) + 3s(450) = 2500

   100s + 1350s = 2500

   1450s = 2500

   s = 2500/1450

   s = 1.72

∴ 3s = 1.72 * 3

By Pythagoras theorem, The given triangle with sides 37 mm, 39 mm, 56 mm is not a right triangle as the theorem is false in this case.

The Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relationship between a right triangle's three sides in Euclidean geometry. In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The Pythagorean Theorem demonstrates how the side lengths of a right triangle can be calculated from the sum of the areas of three intersecting squares. This theorem is a very helpful tool that serves as the foundation for more intricate trigonometry theories like the Pythagorean theorem's opposite.

Here,

We can prove this by Pythagoras theorem,
