Find the slope, or rate of change, from the following ordered pairs:

please help me with this :(

Answer:

The opening balance is the amount of funds in a company's account at the beginning of a new financial period. It is the first entry in the accounts, either when a company is first starting up its accounts or after a year-end.

The initial balance in the account was approximately $4215.

The formula represents the relationship between the initial balance, the interest rate, the compounding period, and the time period.

To determine the initial balance in the account, we can use the formula for compound interest:

A = P(1 + r)ⁿ

where:

A = the ending balance

P = the initial balance

r = the annual interest rate as a decimal (5% = 0.05)

t = the number of years

Substituting the given values, we get:

[tex]5000 = P(1 + 0.05)^{(3.5)}[/tex]

[tex]5000 = P(1.05)^{(3.5)}[/tex]

Dividing both sides by [tex](1.05)^{(3.5)}[/tex], we get:

[tex]P = 5000/(1.05)^{(3.5)}[/tex]

Using a calculator, we get:

P ≈ $4215

Therefore, the initial balance in the account was approximately $4215.

The question seems incomplete, the correct question would be as:

An account with an ending balance of $5000 earns 5% interest for 3.5 years. What is the initial balance in the account?

Step-by-step explanation:

2x+13=-7x+28 =

Solutions:

x = 15

     9

≈ 1.666667

Answer: x= 5/3

Step-by-step explanation:

subtract 13 from both sides of the equation

2x+13=-7x+28

2x+13-13=7x+28-13

simplify

subtract the numbers

2x=-7x+15

add 7x to both sides of the equation

2x+7x=-7x+15+7x

simplify

9x=15

divide

9x/9 = 15/9

simplify

Cancel terms that are in both the numerator and denominator

divide the numbers

x=5/3

Answer:

x=9

Step-by-step explanation:

These angles are equal to each other because they are alternate exterior angles. Thus, we can solve the for the value of x by creating the equation

6x+5=7x-4

From here, we solve it like a normal algebraic equation, isolating the variables and making sure it is on the same side of the other. From there we subtract 7x from both sides, and subtract 5 from both sides, leaving -x = -4-5. Summing up -4-5, we get -x=-9. Now we make them positive on both sides, leaving the answer that x = 9

Given:

To find: The area of the rectangle.

Answer:

Formula to find the area of a rectangle = Length × Breadth.

Since we've calculated the length and breadth, let's substitute them directly.

17/9 × 17/12 = 289/108 = 2.67 [approx.]

Therefore, the area of the rectangle is 2.67 units.

Hope it helps. :)

Answer:

The value of x is 5.8

Step-by-step explanation:

Here. we want to find the value of x

To do this, we need the appropriate trigonometric identity

As we can see 10 is the opposite as it faces the side given

x is the adjacent

The trigonometric identity relating opposite and adjacent is tan . Tan is the ratio of the opposite to the adjacent

Thus, mathematically;

Tan 60 = 10/x

x = 10/tan 60

x = 5.8

Answer:3.55 liters of paint are in each container

Step-by-step explanation:

Total amount of paint ( purple paint ) =Amount of red paint + Blue paint

= 6.42 Liters + 6.87 Liters

=13.29Liters

Amount of paint in the three containers = Total amount of paint ( purple paint ) - amount left over = 13.29- 2.64

=10.65Liters

Amount OF Paint in each container = Amount of paint in the three containers / 3

10.65/ 3

=3.55 liters

Answer: 2%, ROUNDED

Step-by-step explanation:

You must divide 100 (whole percent) by 52 (Cards in a Deck) and you will get 1.92307692308%. But if we round it, we get 2%.

So the answer is 2%.

Answer:

[tex]x=4.375[/tex]

Step-by-step explanation

From the question we are told

Plane A starts at altitude 790

Plane B starts at altitude 1142

Plane A losing altitude at 14 meters per second

Plane B is losing altitude at 22 meters per second

Generally the altitude of both plane is given by

Plane A= [tex]790-14x[/tex]

Plane B=[tex]1142-22x[/tex]

Therefore when they exist in the same altitude

[tex]790-14x[/tex] =[tex]1142-22x[/tex]

[tex]-350=-8x[/tex]

[tex]\frac{-350}{-8} =x[/tex]

Therefore

[tex]x=4.375[/tex]

Answer:

Not a function

Step-by-step explanation:

If it is a function, every input has only one output. Meaning if we graph it, it will pass the vertical line test.

If you want to think about it in x and y, all values of x can only correspond to one value of y.

In this case, we can see that the x-value 6 has 2 corresponding y-values (5 and 10), therefore, this mapping is not a function.

Answer:

For Angles it is parallel angles on parallel lines are the same

Step-by-step explanation:

Answer:

No

Yes

No

Yes

Step-by-step explanation:

In the first 1, the input 2 repeats which makes it not a function

in the second one each input is unique and does not repeat so it is a function

in the third one the input 1 repeats and makes it not repeat

And in the last one each input is unique

If inputs (the x value) repeat it's not a function

Answer:

3000 feets

Step-by-step explanation:

Given that :

Initial Ascent to steady altitude = 35,000 feets

Descent to steady altitude = 32,000 feets

Number of feets the plane descend :

(Initial ascent to steady altitude - descent to steady altitude)

(35000 - 32000) feets = 3,000 feets

Answer:

y = [tex]-9x^2 + 54x + 63[/tex]

Step-by-step explanation:

An equation in standard form is;

[tex]y = ax^2 + bx + c[/tex]

y = -9( x + 1 ) ( x - 7 )

Distribute. multiply every term by another, and combine like terms;

y = -9 ( [tex]x^2 - 6x - 7[/tex] )

y = [tex]-9x^2 + 54x + 63[/tex]

Answer:

he traveled a total of 349.5 miles.

Step-by-step explanation:

*First we convert the 150 minutes to hours, that is :

[tex]h=\frac{1.150}{60} \\h=2.5[/tex]

Now we determine the distance Michael traversed during those 2.5 hours:

[tex]d_{1} =2.5.75 \\d_{1} =187.5\\[/tex]

He transversed 187.5 miles.

We also determine the distance he tranversed the two remaining hours:

[tex]d_{2} =2.81 \\d_{2} =162[/tex]

He also traveled 162 miles

Finally we add both traversed distances:

[tex]d_{t}=187.5+162 \\d_{t} =349.5\\[/tex]

So , he traveled a total of 349.5 miles.

Answer:

Solving the equation for all real solutions in simplest form.

[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]

Step-by-step explanation:

We need to solve the equation for all real solutions in simplest form.

[tex]z^2 - 12z +9= -3[/tex]

First simplifying the equation:

[tex]z^2 - 12z +9+3= -3+3\\z^2 - 12z +12= 0[/tex]

Now, we can solve the equation using quadratic formula:

[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

we have a = 1, b=-12 and c=12

Putting values in formula and finding values of x

[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\z=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(12)}}{2(1)}\\z=\frac{12\pm\sqrt{144-48}}{2}\\z=\frac{12\pm\sqrt{96}}{2}\\z=\frac{12\pm9.8}{2}\\z=\frac{12+9.8}{2}\:or\:z=\frac{12-9.8}{2}\\z=10.9\:or\:z=1.1[/tex]

So, we get value of z: z=10.9 or z=1.1

Solving the equation for all real solutions in simplest form.

[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]
