Can someone help me??

Elza [17]

Answer:

y=0.5x+3

Step-by-step explanation:

So the point of this is to make y the only thing on one side. So first you have to add 6 on both sides. That would make is x+6=2y. Next you need to divide 2 on both sides. That would equal 0.5x+3=y.

Hope this helped!!! :D

Do the ratios 8/3 and 18/7 form a proportion

Anastaziya [24]

Answer:

8 * 7 = 3 * 18

Simplifying

8 * 7 = 3 * 18

Multiply 8 * 7

56 = 3 * 18

Multiply 3 * 18

56 = 54

Solving

56 = 54

Given a square with area x, you can use the formula d = 1.4x 1 2 to estimate the length of the diagonal of the square. Use the f

Firlakuza [10]

Answer:

Step-by-step explanation:

Given a length of the diagonal of a square modeled by the equation

d = 1.4x^1/2 where x is the area of the square, to find the estimate of the length of the square if area is 100cm², we will substitute x = 100 into the modeled equation to get s as shown;

$d = 1.4 x^{1/2}\\\\d = 1.4 (100)^{1/2}\\\\d = 1.4\sqrt{100}\\\\d = 1.4 * 10\\\\d = \frac{14}{10} * 10\\ \\d = 14$

<em>Hence the length of the diagonal of the square using the modeled equation is 14cm</em>

If the typical balance on Lucy's credit card is $650 and the interest rate (APR) on her credit card is 18%, how much in interest

Mariana [72]

$9.75

<h3>Further explanation </h3>

Given:

The typical balance on Lucy's credit card is $650.
The interest rate (APR) on her credit card is 18%.

Question:

How much in interest would you expect Lucy to be charged in a typical month?

The Process:

This problem includes the type of determining simple interest.

$\boxed{ \ I = P \times r \times t \ }$

where,

I = simple interest
P = principal (initial amount)
r = annual interest rate
t = time (in years)

This time we will find out how much in interest we would expect to be charged in a typical month.

The data is as follows:

P = 650
r = 18% or $\frac{18}{100}$ or 0.18
t = $\frac{1}{12}$ year (one month)

Let us calculate how much in interest we would expect to be charged in a typical month.

$\boxed{ \ = 650 \times \frac{18}{100} \times \frac{1}{12} \ }$

$\boxed{ \ = 65 \times \frac{3}{10} \times \frac{1}{2} \ }$

$\boxed{ \ = \frac{195}{10} \times \frac{1}{2} \ }$

$\boxed{ \ = \frac{97.5}{10} \ }$

$\boxed{ \ = \frac{975}{100} \ }$

Thus the amount of interest we would expect Lucy to be charged in a typical month is $ 9.75.

Notes

We must be able to distinguish between simple and compound interest. Please learn about this in the link attached below.

Baxter is thinking about buying a car. The table below shows the projected value of two different cars for three years.

saw5 [17]

Car 1: It is an exponential function that is given as P = 18,500 (0.9595)ⁿ and the price after 10 years is $12,235.5.

Car 2: It is a linear function that is given as 2000x + 3y = 55500 and the price after 10 years is $11,833.33.

And Yes, there is a significant difference.

<h3>What is a function?</h3>

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

Baxter is thinking about buying a car. The table below shows the projected value of two different cars for three years.

Car 1 (value in dollars)

Year 1: 18,500

Year 2: 17,390

Year 3: 16,346.60

Car 2 (value in dollars)

Year 1: 18,500

Year 2: 17,500

Year 3: 16,500

The exponential function describes car 1.

Then the function will be

$\rm P = 18500\times (0.95995)^n$
