Answer:

Two solutions were found :

x=10/3

x=-6

Step-by-step explanation:

|3x+4|=14  

Two solutions were found :

x=10/3

x=-6

Absolute Value Equation entered :

     |3x+4|=14  

Step by step solution :

Step  1  :

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |3x+4| = 14  

Step  2  :

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |3x+4|

For the Negative case we'll use -(3x+4)  

For the Positive case we'll use (3x+4)  

Step  3  :

Solve the Negative Case

     -(3x+4) = 14  

    Multiply

     -3x-4 = 14  

    Rearrange and Add up

     -3x = 18  

    Divide both sides by 3  

     -x = 6  

    Multiply both sides by (-1)  

     x = -6  

    Which is the solution for the Negative Case

Step  4  :

Solve the Positive Case

     (3x+4) = 14  

    Rearrange and Add up

     3x = 10  

    Divide both sides by 3  

     x = (10/3)  

    Which is the solution for the Positive Case

Step  5  :

Wrap up the solution

ANSWER

He did not square 40, he just multiplied by 2.

EXPLANATION

According to the Pythagoras Theorem, the sum of the square of the shorter legs equals the square of the Hypotenuse.

Hans correctly applied the Pythagoras Theorem to obtain:

[tex] {9}^{2} + {40}^{2} = {c}^{2} [/tex]

The next correct step is to evaluate the squares to obtain:

[tex]9 \times 9+ {40} \times 40= {c}^{2} [/tex]

Which gives

[tex]81+1600= {c}^{2} [/tex]

But Hans mistakenly multiplied the exponent of the second square by the base to get

[tex]9 \times 9+ {40} \times2= {c}^{2} [/tex]

Which simplifies to;

[tex]81+ 80= {c}^{2} [/tex]

Therefore the error is that,he did not square 40, he just multiplied by 2.

The first choice is correct.

Answer:

Error: He did not square 40, he multiplied by 2

In calculation of 40² ( Correct was 1600 but he did 80)

The length of hypotenuse is 41 cm

Step-by-step explanation:

Given: In the given right angle triangle.

The two legs are 40 and 9.

The hypotenuse is c

Using Pythagoras theorem,

[tex]c^2=a^2+b^2[/tex]

where, a and b are legs and c is hypotenuse

a=40 , b=9

Substitute into formula

[tex]c^2=40^2+9^2[/tex]

[tex]c^2=1600+81[/tex]     Error        

Hans did mistake here to calculate square of 40.

instead of square Hans multiply 40 and 2.

[tex]c^2=1600+81[/tex]  

[tex]c^2=1681[/tex]

Taking square root

[tex]c=\sqrt{1681}[/tex]

[tex]c=41[/tex]

Hence, The length of hypotenuse is 41 cm

Error: In calculation of 40²

Answer:

1 2 3 4 5 6 7 8 9 10 11 12

45 is the 12th term

Answer:

Option b - 45

Step-by-step explanation:

Given : Sequence 12,15,18,21,...

To find : What is the 12th term in the sequence?

Solution :

Sequence 12,15,18,21,... is an arithmetic progression.

Where, first term is a=12

Common difference is d=15-12=3

The nth term of the sequence is

[tex]a_n=a+(n-1)d[/tex]

The 12th term is

[tex]a_{12}=12+(12-1)(3)[/tex]

[tex]a_{12}=12+(11)(3)[/tex]

[tex]a_{12}=12+33[/tex]

[tex]a_{12}=45[/tex]

Therefore, The 12th term of the sequence is 45.

So, Option b is correct.

Step-by-step explanation:

hihi, so the key to this is manipulating the equations. Realizing that 7a + 7b is just 7*(a+b) makes this fairly simple since you already know what a+b equals and just have to multiply that by 7. Same goes with x, y, and z. 6x + 6y + 6z is the same as 6(x + y + z). Thus, -1 * 7 + 2 * 6 = 5

Answer:

[tex]\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}[/tex]

Step-by-step explanation:

The length of the base is the distance between the points 4+2i and 10+4i, so

[tex]\text{Base}=|10+4i-(4+2i)|=|10+4i-4-2i|=|6+2i|=\sqrt{6^2+2^2}=\\ \\=\sqrt{36+4}=\sqrt{40}[/tex]

The middle point of the base is placed at point

[tex]\dfrac{4+2i+10+4i}{2}=\dfrac{6i+14}{2}=7+3i[/tex]

The length of the height is the distance between the points 5+9i and 7+3i

[tex]\text{Height}=|5+9i-(7+3i)|=|5+9i-7-3i|=|-2+6i|=\sqrt{(-2)^2+6^2}=\\ \\=\sqrt{4+36}=\sqrt{40}[/tex]

So, the area of the triangle is

[tex]A=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}[/tex]

ANSWER

C. x=2

EXPLANATION

The given equation is

[tex] \frac{x + 4}{6x} = \frac{1}{x} [/tex]

Cross multiply to get,

[tex]6x = x(x + 4)[/tex]

Expand to get:

[tex]6x = {x}^{2} + 4x[/tex]

[tex] {x}^{2} + 4x - 6x = 0[/tex]

[tex] {x}^{2} - 2x = 0[/tex]

[tex]x(x - 2) = 0[/tex]

[tex]x = 0 \: or \: x = 2[/tex]

But the domain is

[tex]x \ne0[/tex]

Therefore the solution is x=2.

First subtract 17 to both sides (what you do on one side you must do to the other). Since 17 is being added, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

p + 17 - 17 < 19 - 17

p + 0 < 2

p < 2  

For the graph will you have a empty or colored in circle?

If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.

If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.

Which direction will the ray go?

If the variable is LESS then the number then the arrow will go to the left of the circle.

If the variable is MORE then the number then the arrow will go to the right of the circle.

In this case your inequality is:

p < 2

aka p is less then two

This means that the graph will have an empty circle and the arrow will go to the left of 2. (image below)

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

[tex]=5.15-3.88=1.27[/tex]

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

[tex]=\frac{1.27}{5.15} *100=24.66[/tex]

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

[tex]=2.25-1.56=0.69[/tex]

% reduction in price of grape fruits

(reduction value/original value)×100

[tex]=\frac{0.69}{2.25} *100=30.67[/tex]

Step-by-step explanation:

I just took a quiz.

Answer: 4. The graph of f(2) will be above the graph of g(2) for all values of x

1. y is always 22 no matter what x value, g(2) = 22. However f(x) is a linear equation which increases vertically right up, so the y = (-∞, ∞ )

So not accurate

2. f(x) meets y axis at (0,50) while g(x) meets at (0,22), however, g(2) is (2,22) while f(x) is 190.

So not accurate

3. graph g(x) is not above f(2)

4. It is accurate

Answer:

The equation of the parallel line is x + 2y = a

Step-by-step explanation:

* lets revise the general form of the linear equation

- The general form of the linear equation is ax + by + c = 0, where

 a , b , c are real numbers

- The linear equation represented by a line its slope = -a/b and

  intersects the y-axis at point (0 , -c/b) means y-intercept = -c/b

- The parallel lines have equal slopes and different y-intercepts

* Now lets solve the problem

- There is a line with equation x + 2y = 7

- Put the equation in the general form

∵ x + 2y = 7 ⇒ subtract 7 from both sides

∴ x + 2y - 7 = 0

∵ ax + by + c = 0 is the general form of the linear equation

∴ a = 1 , b = 2 , c = -7

∵ The slope of the line is -a/b

∴ The slope of the line -1/2

- We need to find the equation of the parallel line which has the

  same slope

∵ The two lines are parallel

∴ Their slopes are equal

∴ The slope of the line is -1/2

∵ The slope depends on a and b

∴ The line has the same value of a and b

∵ a = 1 and b = 2

∵ ax + by + c = 0

∴ The equation of the line is x + 2y + c = 0

- To find c substitute x and y in the equation by the coordinates of

  any point on the line

∵ The line passing through point (a , 0)

- Substitute x by a and y by 0

∴ a + 2(0) + c = =

∴ a + c = 0 ⇒ subtract a from both sides

∴ c = -a

- Substitute the value of c in the equation by - a

∴ The equation of the line is x + 2y - a = 0 ⇒ add a for both sides

∴ The equation of the line is x + 2y = a

* The equation of the parallel line is x + 2y = a

- They are equal in slopes and different in y-intercepts

Final answer:

The equation of the line passing through the point (a, 0) and parallel to x + 2y = 7 is y = -0.5x + 0.

Explanation:

To find the equation of a line parallel to the line x + 2y = 7 and passing through the point (a, 0), we need to determine its slope. This can be done by rearranging the given equation in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

First, we rewrite the given equation as 2y = -x + 7 and then divide everything by 2 to get y = -0.5x + 3.5. Since the line we're looking for is parallel to this line, it will have the same slope of -0.5.

So, the equation of the line passing through (a, 0) and parallel to x + 2y = 7 is y = -0.5x + 0.
