The properties used, in order, are:

Distributive.Addition or subtraction property of equality.Addition or subtraction property of equality.multiplicationn or division property of equality.

What is used in each step of the demonstration?

We start by writing the linear equation:

3*(x + 2) = 4x + 1

The first step is using the distributive property to distribute the left product.

3x + 6 = 4x + 1

Then we use the addition property of equality to subtract 4x in both sides, we will get:

-x + 6 = 1

And we use it again to subtract 6 in both sides:

-x = 1 - 6 = -5

Finally, we multiply both sides by -1 (multiplication property of the equality)

x = 5

That is the solution of the linear equation.

What is consecutive integers?

Whole numbers that followed each other with no gaps are known as consecutive integers. For example, the numbers 15, 16, and 17 are all consecutive integers. If is an integer, then the following consecutive integers begin at:,, and so on.

According to the given data:

A divider counting argument can be employed because each member of the subgroups must be at least two apart.

We select no more than four numbers first from set 1,2,3,4,5,6,7,8,9,10,11,12. Let's use balls to represent these numbers. There are least two dividers between each of the balls.

So for example, o | | o | | o | | o | | represents {1,4,7,10}.

There must be 2(k - 1) dividers between both the balls in subsets of size k, leaving 12 - k - 2(k - 1) = 12 - 3k + 2 dividers to be placed at k + 1 spots between the balls.

[tex]\left(\begin{array}{c}(12-3 k+2)+(k+1)-1 \\k\end{array}\right)=\left(\begin{array}{c}12-2 k+2 \\k\end{array}\right)[/tex]

As a result, the number of spacy subsets is reduced:

[tex]\left(\begin{array}{l}6 \\4\end{array}\right)+\left(\begin{array}{l}8 \\3\end{array}\right)+\left(\begin{array}{c}10 \\2\end{array}\right)+\left(\begin{array}{c}12 \\1\end{array}\right)+\left(\begin{array}{c}14 \\0\end{array}\right)[/tex] = 129

Perpendicular lines are lines that intersect at a 90-degree angle. So, for example, line ST is perpendicular to line CD. So line ST is perpendicular to line CD.

Perpendicular lines always intersect each other, however, all intersecting lines are not always perpendicular to each other. The two main properties of perpendicular lines are: Perpendicular lines always meet or intersect each other. The angle between any two perpendicular lines is always equal to 90.

Given that

line m and n are perpendiculars

then angle ∠a = ∠b

then

5x + 20 = 7x -4

7x -5x = 20 + 4

2x = 24

You are 5 feet 4 inches tall and cast a shadow 3 feet long. At the same time, a nearby water tower casts a shadow 74 feet 3 inches long.

a. Find the height of the water tower.

Answers

The height of the water tower is 132 feet

How to solve for the height of the tower

We have the height to be 5 feet 4 inches

then 1 feet = 12 inches

inch = 1 / 12 ft

Then 4 inches = 1 / 12 x 4

= 1 / 3 ft

Height = 5 1/3

= 16 / 3

height of the shadow cast = 3 feet

For the water tank

74 ft 3 inches

= 74 x 3 / 12

297 / 4

the height of the tower

[tex]\frac{height of person}{height of shadow} =\frac{height of tower}{height of person}[/tex]

= [tex]\frac{16/3}{3} =\frac{x}{297/4} \\\\\frac{16}{3*3} =\frac{4x}{297}[/tex]

Then x = 132

Therefore the height of the water tower is 132 feet

4. Technology required. Priya starts with $50 in her bank account. She then deposits $20

a. Write an equation that represents the relationship between the dollar amount
in her bank account and the number of weeks of saving.
d=50+20w
b. Graph your equation using graphing technology. Mark the point on the graph
that represents the amount after 3 weeks.

Answers

The equation [tex]d=50+20w[/tex] represents the relationship between dollar amount in her bank account and the number of weeks of savings.

The definition of an equation is a formula that states that two formulas are equal. For example, 3x + 5 = 14 is an equation where 3x + 5 and 14 are two terms separated by an equal sign. The most basic and simple algebraic equations consist of one or more variables in mathematics. In mathematics, a graph can be defined as a graphical representation or chart that systematically represents data or values. A point on a graph often represents a relationship between two or more things.

(a) It is given that amount in bank account is $50 , amount deposited by Priya is $20 and time period is 12 weeks .

Let " d " be the dollar and " w " be the weeks

Multiply the number of weeks w by 20 to get the total savings and add up how much money she had in the account initially.

Money deposit by Priya in 1 week = $20

Money deposit by Priya in 1 week = [tex]20\times w[/tex]

Therefore , the equation will be [tex]d=50+20w[/tex]

(b) Graph of given equation is given below :

Let " w " represents the x - axis and " d " represents the y - axis

For 1 week , amount will be [tex]d=50+20=60[/tex]

For 2 week , amount will be [tex]d=50+20(2)=90[/tex]

For 3 week , amount will be [tex]d=50+20(3) = 110[/tex]

Answers

The value of x of the first rectangular deck is 8.

For given question,

The perimeter of a one rectangular deck is 78 feet.

The length of the first rectangular deck is  represented as (2x + 3), and its width is represented as (3x-4).

Similarly, the perimeter of a second rectangular deck is 2 times the perimeter of the first deck with a length of (4x + 6) and a width of (6x -1).

We need to find the value of x of the first rectangular deck.

Let P1 be the perimeter of the first rectangular deck.

⇒ P1 = 2 × (length + width)

⇒ 78 = 2 × [(2x + 3) + (3x - 4)]

⇒ 39 = (2x + 3x + 3 - 4)

⇒ 39 = 5x - 1

⇒ 40 = 5x

⇒ x = 40/5

⇒ x = 8

Therefore, the value of x of the first rectangular deck is 8.

The end behavior of the second graph is that as x → ∞, f(x) → -∞ and x → -∞, f(x) → -∞

An asymptote is defined as a line that a curve approaches, as it heads towards infinity. There are three types of Asymptotes namely horizontal, vertical and oblique.

It is called a Horizontal Asymptote when as x goes to positive or negative infinity the curve approaches some constant value.

It is called a Vertical Asymptote when as x approaches some constant value (from the left or right) then the curve goes towards positive or negative infinity

Over the weekend she walked a total distance of (4 + 5/8) miles

How many total miles did she walk over the weekend?

We know that on Saturday she walked a total of (3 + 7/10) miles (so we need to work with mixed numbers), and on Sunday she walked 0.25 of that distance.

Then the  distance that she walked on Sunday is:

D = 0.25*(3 + 7/10) miles

We can rewrite: 0.25 = 1/4

replacing that:

D = (1/4)*(3 + 7/10) mi = (3/4 + 7/40) mi

   = (30/40 + 7/40)mi = (37/40)mi

Then the total distance that she walked over the weekend is:

d = (3 + 7/10) mi +  (37/40)mi

  = (120/40 + 28/40) mi + (37/40) mi

  = (185/40)mi = (160/40 + 25/40) mi = (4  + 5/8) mi
