Step-by-step explanation:

For volume problems (with prisms, such as cardboard boxes) all you have to do is multiply all the dimensions, height, width, and length.

To solve the equation, we can use algebraic techniques to find the value of 'x'.

To solve the equation, we can let the number be represented by 'x'. The equation can then be written as: (1/5)x + 5x = 7x - 18. Simplifying this equation gives us: (1/5)x + 5x - 7x = -18. Combining like terms, we get: (6/5)x = -18. Dividing both sides by 6/5 gives us the value of 'x'.

Follow below steps:

The question involves solving a linear equation to find an unknown number. To solve "one fifth of a number plus five times that number is equal to seven times the number less 18", the first step is to let "x" represent the unknown number and then create an equation based on the given information.

We start by translating the words into an equation:

One fifth of a number can be written as "(1/5)x".

Five times that number is written as "5x".

Seven times the number less 18 is written as "7x - 18".

So our equation becomes "(1/5)x + 5x = 7x - 18". Simplifying, we get "(6/5)x = 7x - 18".

Combining like terms yields "(1/5)x = -18", and we solve for x to find the value of the unknown number: "x = -90".

Through this process, the student can identify the value of the number in question.

Answer:

The corresponding point is (-4.-1)

Step-by-step explanation:

we know that

The point (-4,2) is on the graph of f(x)

so

For x=-4

f(x)=2

therefore

For x=-4

-(1/2)f(x)=-(1/2)*2=-1

The corresponding point is (-4.-1)

For this case we have that by definition, if we draw the diagonal of a square two rectangular triangles are formed. If the diagonal measures "x", then the Pythagorean theorem is fulfilled:

[tex]l ^ 2 + l ^ 2 = x ^ 2[/tex]

Where:

l: It's the side of the square.

[tex]2l ^ 2 = x ^ 2\\l ^ 2 = \frac {x ^ 2} {2}[/tex]

We know that the area of a square is given by:

[tex]A = l ^ 2[/tex]

So, the area is:

[tex]A = \frac {x ^ 2} {2}[/tex]

B. 11x^2 − x + 10

Step-by-step explanation:

(5x^2 + 2x + 1) + (6x^2 − 3x + 9)

I like to line them up vertically

  (5x^2 + 2x + 1)

+ (6x^2 − 3x + 9)

---------------------------

11 x^2  -  x   + 10

The statement that is true in every aspect regarding his claim is:

The series is given as:

[tex]\sum_{n=0}^{3} (-\dfrac{1}{3})^n\cdot 9[/tex]

which could also be written by:

[tex]\sum_{n=0}^{3} (-\dfrac{1}{3})^n\cdot 9=\sum_{n=0}^{3} (-\dfrac{1}{3})^n\cdot 3^2\\\\\\\sum_{n=0}^{3} (-\dfrac{1}{3})^n\cdot 9=\sum_{n=0}^{3} (-1)^n(\dfrac{1}{3})^n\cdot 3^2[/tex]

i.e.

[tex]\sum_{n=0}^{3} (-\dfrac{1}{3})^n\cdot 9=\sum_{n=0}^{3} (-1)^n\cdot 3^{-n}\cdot 3^2\\\\\\\sum_{n=0}^{3} (-\dfrac{1}{3})^n\cdot 9=\sum_{n=0}^{3} (-1)^n\cdot 3^{2-n}[/tex]

which is not equivalent to: [tex]\sum_{n=0}^{3} 3^{2-n}[/tex]

Since,  on expanding the actual series we get the sum as:

[tex]\sum_{n=0}^{3} (-\dfrac{1}{3})^n\cdot 9=(-\dfrac{1}{3})^0\cdot 9+(-\dfrac{1}{3})^1\cdot 9+(-\dfrac{1}{3})^2\cdot 9+(-\dfrac{1}{3})^3\cdot 9\\\\\\=9-\dfrac{1}{3}\times 9+\dfrac{1}{3^2}\times 9-\dfrac{1}{3^3}\times 9\\\\\\=9-3+1-\dfrac{1}{3}\\\\\\=\dfrac{22}{3}[/tex]

Now, the expansion of:

[tex]\sum_{n=0}^{3} 3^{2-n}[/tex] is:

[tex]\sum_{n=0}^{3} 3^{2-n}=3^2+3^1+3^0+3^{-1}\\\\\\=9+3+1+\dfrac{1}{3}=\dfrac{40}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{a-3}{15a}[/tex] × [tex]\frac{5}{a-3}[/tex]

Cancel the factor (a - 3) on the numerator and denominator

Cancel the 5 and 15 by dividing both by 5, leaving

[tex]\frac{1}{3a}[/tex]

Answer:  The required answer is [tex]\dfrac{1}{3a},~a\neq 3.[/tex]

Step-by-step explanation:  We are given to find the following product :

[tex]P=\dfrac{a-3}{15a}\times\dfrac{5}{a-3}~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Since (a - 3) is present in both numerator and denominator, so we can divide them if

[tex]a-3\neq 0\\\\\Rightarrow a\neq 3.[/tex]

Then, we get from (i) that

[tex]P\\\\\\=\dfrac{(a-3)}{15a}\times\dfrac{5}{(a-3)}\\\\\\=\dfrac{5}{15a}\\\\\\=\dfrac{1}{3a}.[/tex]

Thus, the required answer is [tex]\dfrac{1}{3a},~a\neq 3[/tex]

Answer:

R = 134

Step-by-step explanation:

This is a 5 sided figure.  The interior angles add to  (n – 2)180  where n is the number of sides

(5-2) * 180 = 540

Add up all the angles and set it equal to 540

R+ 78+109+113+106 = 540

Combine like terms

R + 406 = 540

Subtract 406 from each side

R +406-406 = 540-406

R = 134

Answer:

(x - 7)(x - 2)

Step-by-step explanation:

Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)

The factors are - 7 and - 2, since

- 7 × - 2 = + 14 and - 7 - 2 = - 9, hence

x² - 9x + 14 = (x - 7)(x - 2) ← in factored form

Answer: Infinitely many

Step-by-step explanation:

First simplify the right side by adding 5 and 2

now you have the equation 4y+7=7+4y

That is the exact same thing so any number works.

just to add to the great reply above.

[tex]\bf \begin{matrix} 4y \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}+7=5+2~~\begin{matrix} +4y \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}\implies 7=7[/tex]

whenever you end up with something like 0 = 0, or 7 = 7, is a flag that both equations are exactly the same, in this case, the one on the right-hand-side is really the one one the left-hand-side in disguise.

So the graph of one, is the same as the graph of the other, or put in another words, let's say the graph the first one, the second one when graphed, will just be pancaked on top of the first one, and any point whatsoever on the second one, matches with the first one, and since both lines continue infinitely, then infinitely many solutions.

4/6 divided by 2/6 is 2.

Answer:

1st option

Step-by-step explanation:

By observation, we can see that the graph crosses the y-axis at y = -2. Therefore the y-intercept is -2.

we can also see that the graph intersects the axes at  (0,-2) and (3,0)

the formula for a linear slope when given two points (x1, y1) and (x2,y2) is given by :

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

In our case, x1 = 0, y1 = -2, x2= 3 and y2 = 0

hence m = (0 - (-2)) / (3-0) = 2/3

Hence the slope is 2/3

Only option 1 satisfies the values for both y-intercept and slope that we calculated.

Answer:

A) The slope is 2/3 and the y intercept is -2

b.1) The measure of each interior angle of pentagon is 108°

b.2) The measure of each interior angle of hexagon is 120°

b.3) The measure of each interior angle of decagon is 144°

b.4) The measure of each interior angle of dodecagon is 150°

Part 2) The central angle and the interior angle are supplementary angles

Part 3) As the number of sides increases, the central angle decreases and the interior angle increases.

Step-by-step explanation:

Part 1. For each polygon, include the following information in the paragraph box below:

a) What was the central angle you used to locate the vertices? Show your calculation.

we know that

To find the central angle divide 360 degrees by the number of sides of the polygon

case a.1) Pentagon

The pentagon has 5 sides

so

The central angle is equal to

360°/5=72°

case a.2) Hexagon

The pentagon has 6 sides

so

The central angle is equal to

360°/6=60°

case a.3) Decagon

The pentagon has 10 sides

so

The central angle is equal to

360°/10=36°

case a.4) Dodecagon

The pentagon has 12 sides

so

The central angle is equal to

360°/12=30°

b) What is the measure of each interior angle of the polygon? Show your calculation

we know that

The sum of the interior angle of the polygon is equal to

S=(n-2)*180°

where

n is the number of sides

To find each the measure of each interior angle, divide the sum of the interior angles by the number of sides

case b.1) Pentagon

The pentagon has 5 sides

so

S=(n-2)*180°

S=(5-2)*180°=540°

Divide by the number of sides

The measure of each interior angle is equal to

540°/5=108°

case b.2) Hexagon

The hexagon has 6 sides

so

S=(n-2)*180°

S=(6-2)*180°=720°

Divide by the number of sides

The measure of each interior angle is equal to

720°/6=120°

case b.3) Decagon

The hexagon has 10 sides

so

S=(n-2)*180°

S=(10-2)*180°=1,440°

Divide by the number of sides

The measure of each interior angle is equal to

1,440°/10=144°

case b.4) Dodecagon

The hexagon has 12 sides

so

S=(n-2)*180°

S=(12-2)*180°=1,800°

Divide by the number of sides

The measure of each interior angle is equal to

1,800°/12=150°

Part 2. What is the relationship between the central angle and the interior angle?

we know that

The sum of the central angle plus the interior angle is equal to 180 degrees

therefore

The central angle and the interior angle are supplementary angles

Verify

Pentagon

72°+108°=180°

Hexagon

60°+120°=180°

Decagon

36°+144°=180°

Dodecagon

30°+150°=180°  

Part 3. As the number of sides increases, how do the angles change?

we know that

As the number of sides increases, the central angle decreases and the interior angle increases.

Answer:

x = 4.

Step-by-step explanation:

log(x) + log(x+5) = log(6x +12)

log x(x +5) = log(6x + 12)

Therefore x(x + 5)= 6x +12

x^2 + 5x - 6x - 12 = 0

x^2 - x - 12 = 0

(x - 4)(x + 3) = 0

x = -3, 4.

logs of negative values do not exists so the anser is x = 4.

The value of x  is -3 , 4 ; option C is the solution to the equation

What is an Equation ?

An equation is a mathematical statement between two algebraic expressions equated by an equal sign.

A logarithm equation is given in the question.

log(x)+ log(x+5) = log(6x +12)

The equation of Logarithm says

log (x .y) = log x + log y

From the equation

log(x)+ log(x+5) can be written as log (x(x+5))

log (x(x+5)) = log(6x +12)

We can relate this as

(x(x+5)) = 6x +12

x² + 5x = 6x +12

x² -x -12= 0

x² -4x +3x -12 = 0

x (x-4)+3(x-4) = 0

(x+3)(x-4) = 0

x = -3 , x=4

Step-by-step explanation:

[tex]x^2+y^2-6y-12=0[/tex] We need to solve this equation to become in standard form to find the value of k.

[tex]x^2+y^2-6y-12=0\\x^2+y^2-6y = 12\\(x)^2 +(y^2-2(y)(3)+(3)^2) = 12 +(3)^2\\(x)^2+(y-3)^2 = 12+9\\(x)^2 +(y-3)^2 = 21[/tex]

The given standard form is:

[tex]x^2+(y-k)^2=21[/tex]

Comparing it with [tex](x)^2 +(y-3)^2 = 21[/tex]

The value of k =3

Answer:

k = 3

Step-by-step explanation:

Equation of the given function has been given as x² + y² - 6y - 12 = 0.

We have to convert this equation in the standard form of x² + (y - k)² = 21 to get the value of k.

x² + y² - 6y - 12 = 0

x² + y² - 6y + 9 - 9 - 12 = 0

x² + [y²- 2(3y) + 3²] - 21 = 0

x² + (y - 3)²- 21 = 0

x² + (y - 3)² = 21

Now by comparing this equation with the standard form of the equation we get the value of k = 3
