Answer:

Step-by-step explanation:

19-13=6+1=7-14=-7+4=-3

The integer represents the price of a share at the end of the day will be negative 3.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The price of a share of stock started the day at $19. During the day it went down $13 up $1, down $14, and up $4.

Then the integer represents the price of a share at the end of the day will be

⇒ 19 - 13 + 1 - 14 + 4

⇒ -3

The integer represents the price of a share at the end of the day will be negative 3.

Answer:

24th term

Step-by-step explanation:

The value of the nth term is 72. Then the position of the nth term will be 24.

A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The explicit rule for a sequence and one of the specific terms is given.

fₙ = (3n - 3) + 3

If the value of the nth term is 72. Then the position of the term is given as,

72 = (3n - 3) + 3

72 = 3n - 3 + 3

72 = 3n

n = 72 / 3

n = 24

The value of the nth term is 72. Then the position of the nth term will be 24.

Answer:

42/12

Step-by-step explanation:

3 1/2 in improper fraction form is 7/2. We can see the denominator in the equivalent fraction is 12. In order for that to happen, the common factor that must have been multiplied is 6. So the numerator of the equivalent fraction should be 42 because:

                         7            42

                       ___ =    ____

                         2            12

42/12

The answer is [tex]\frac{42}{12}[/tex]

First, you must simplify both sides if the equation.

[tex]\frac{7}{2}=\frac{x}{12}[/tex]

Then, multiply both sides by 12

[tex]42=x[/tex]

[tex]x=42[/tex]

Finally, substitute in 42 for x

[tex]3\frac{1}{2}=\frac{42}{12}[/tex]

Option C: Line s

Step-by-step explanation:

Let's refer to plane H as being 2D since we are dealing with lines.

Thus, x-axis would refer to the horizontal axis while y-axis will refer to the vertical axis.

Now, we are told that line q goes through plane H in the center at point X and that Line t is one that comes out from point X.

This means that line q and line t are parallel to each other.

Also, we are told that Lines r and s are parallel and that they're at a right angles to line q.

Since line q and line t are parallel to each other, it means that lines r and s are at right angles to both lines q and t

Thus, it means lines r and s are both perpendicular to lines q and t

Now, we are told that line p goes through r and s.

However, we want to find which line is parallel to line r.

From earlier statement we saw that lines r and s are parallel to each other.

Thus; correct answer is "line s"

Answer:

=18y+47

Step-by-step explanation:

Let's simplify step-by-step.

14y−(y−2)+5(y+9)

Distribute:

=14y+−y+2+(5)(y)+(5)(9)

=14y+−y+2+5y+45

Combine Like Terms:

=14y+−y+2+5y+45

=(14y+−y+5y)+(2+45)

=18y+47

Answer:

y = -2 11/18 or y = -2.6111 repeating

Step-by-step explanation:

14y -(y - 2) + 5(y + 9)

    Distribute the negative (-) to (y - 2)

    Distribute the five (5) to (y + 9)

14y -y + 2 + 5y + 45

    Combine like terms

18y + 47 = 0

       -47 = -47

18y = -47

18y/18 = -47/18

y = -2 11/18

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Answer:

37 boxes

Step-by-step explanation:

you should try and write each of the steps into an equation of x. Where x is the boxes she started with

so, she had x boxes, she bought 7 (that's addition) and then half of those boxes (that's division) got destroyed in the fire and she has 22 left (that's your total).

you can write the equation like this:

(x+7)/2 = 22

then, you solve

(x+7) = 44

x = 37

she originally had 37 boxes

Answer:

The first multiple of 7 = 14 or -21

The second multiple of 7 = 21 and -14

Step-by-step explanation:

Let

The first multiple of 7 = 7x

The second multiple of 7 = 7(x+1)

Square of the first multiple = (7x)^2

Square of second multiple = {7(x+1)}^2

Sum

(7x)^2 + 7(x+1)}^2 = 637

49x^2 + 49(x+1)^2 = 637

Divide through by 49

x^2 + (x+1) = 13

Open bracket

x^2 + x^2 + 1 + 2x = 13

Subtract 13 from both sides

x^2 + x^2 + 1 + 2x - 13 = 13 - 13

x^2 + x^2 + 1 + 2x - 13 = 0

2x^2 + 2x - 12 = 0

Divide through by 2

x^2 + x - 6 = 0

Solve the quadratic equation using factorization method

x^2 + 3x - 2x - 6 = 0

x(x+3) - 2(x+3) = 0

(x - 2) (x+3) = 0

x - 2 = 0

x = 2

x+3 = 0

x = -3

Substitute x = 2 or -3 into 7x

When x= 2

7(2) = 14

When x = -3

7(-3) = -21

The first multiple of 7 = 14 or -21

Substitute x = 2 or -3 into 7(x+1)

When x= 2

7(2+1) = 7(3) = 21

When x = -3

7(-3+1) = 7(-2) = -14

The second multiple of 7 = 21 and -14

Answer:

actual answe is root under 2

Answer: 28.

Step-by-step explanation:

Let's define D = # of marbles in Damon's bag at the beginning.

First, he gave D/2 + 2 marbles to Artemio, so now he has:

(D - D/2 - 2) = (D/2 - 2) marbles left.

Now, he gives 1/4 plus of what he has left plus 5 to Banou, so he gives:

(D/2 - 2)/4 + 5 marbles to Banou.

Then Damon has now:

(D/2 - 2) - (D/2 - 2)/4 - 5 = 3*(D/2 - 2)/4 - 5.

Now Damon gives half of this to Alex, then the amount that he has left is:

(3*(D/2 - 2)/4 - 5)/2

And we know that this is equal to 2, then we can solve this equation as:

(3*(D/2 - 2)/4 - 5)/2 = 2

Let's solve this for D.

(3*(D/2 - 2)/4 - 5) = 2*2 = 4.

3*(D/2 - 2)/4 = 4 + 5 = 9

3*(D/2 - 2) = 9*4 = 36

(D/2 - 2) = 36/3 = 12

D/2 = 12 + 2 = 14

D = 2*14 = 28

Damon initially had 28 marbles.

Step-by-step explanation:

y= 1/2x - 2

To find the x intercept, set y =0 and solve for x

0= 1/2x - 2

Add 2 to each side

2 = 1/2x -2+2

2 = 1/2x

Multiply by 2

2*2 = 1/2x *2

4 =x

The x intercept is 4
