1. Determine the equation for the line of

2. Include the two points you used to find the slope.

3. Verify your equation is correct by substituting a given point on the line into your equation.

Answers

Answer:

y=

[tex] \frac{2}{15} [/tex]

x+10

Step-by-step explanation:

we know the y-intercept : (0,10)

picking another point on the line, (2,25)

finding slope is

[tex] \frac{y2 - y1}{ x2 - x1} [/tex]

so inserting that together is:

[tex] \frac{2 - 0}{25 - 10} [/tex]

that equals to,

[tex] \frac{2}{15} [/tex]

and since we already have the y-intercept you take the 10 to replace the b in the equation y=x+b

meaning x = slope and b = y-intercept

equation all together

y =

[tex] \frac{2}{15} [/tex]

x + 10

Christiana and Marlena opened their first savings accounts on the same day. Christiana opened her account with $55 and plans to deposit $10 every month. Marlena opened her account with $20 and plans to deposit $15 every month. After how many months will their two accounts have the same amount of money? What will that amount be?

The two accounts will have the same amount of money in BLANK months. And, the amount will be $ BLANK

Answers

Answer: it will take 4 months for the amount to be the same and the amount would be $95

Step-by-step explanation:

Let x represent the number if months it will take for the two accounts have the same amount of money.

Christiana opened her account with $55 and plans to deposit $10 every month. This means that the amount that in the account after x months would be

10x + 55

Marlena opened her account with $35 and plans to deposit $15 every month. This means that the amount that in the account after x months would be

15x + 35

For the amount in the accounts to be the same, the number of months would be

15x + 35 = 10x + 55

15x - 10x = 55 - 35

5x = 20

x = 20/5

x = 4

The amount would be

15 × 4 + 35

= 60 + 35

= $95

it will take 4 months for the amount to be the same and the amount would be $95

Sue earns $6 an hour walking her neighbor's dog.

Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points)

Part B: List three ordered pairs to show the values of the two variables. (3 points)

Part C: Write an equation to represent the relationship between the two variables. (3 points)

Answers

is that all that the question says ?

(A) The independent variable is time because it is something that can be controlled and changed by the person walking the dog.

(B) Three ordered pairs are (1, 6), (2, 12), (0.5, 3).

(C) The equation is:

Money earned = 6t

What is an expression?

In mathematics, an expression is a combination of numbers, variables, and operations that are grouped together to represent a mathematical statement.

Part A:

In this situation, the two variables are:

Independent variable: Time (in hours) spent walking the dog

Dependent variable: Amount of money earned (in dollars)

The independent variable is time because it is something that can be controlled and changed by the person walking the dog. The dependent variable is the amount of money earned because it is directly affected by the amount of time spent walking the dog.

Part B:

Here are three possible ordered pairs to show the values of the two variables:

(1, 6) - Sue earns $6 for walking the dog for 1 hour.

(2, 12) - Sue earns $12 for walking the dog for 2 hours.

(0.5, 3) - Sue earns $3 for walking the dog for half an hour (30 minutes).

Part C:

The relationship between the two variables can be represented by the equation:

Money earned = Hourly rate x Time spent walking

In this case, the hourly rate is $6 and the time spent walking is represented by the variable "t". Therefore, the equation is:

Money earned = 6t

where "t" is the time (in hours) spent walking the dog and "6t" is the amount of money (in dollars) earned for that time.

Answers

Answer:

Step-by-step explanation:

Answer:

The correct answer is $2.50.

Step-by-step explanation:

The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.

We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.

To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:

12.50 / 5 = 2.50

In this way we can verify that the unit price of 5 ounces

1675/3890 you are dividing 1675 by 3890 so it equals 0.43059...=0.4 simplified to the first decimal

If you want to divide it in long division then the answer would be, 0.430591

but if you want to simplify the fraction the answer would be

[tex] \frac{335}{778} [/tex]

or if u want it in percent form it would be, 43.059126%

What is the value of x+y?

Eight grade math

Answers

Hello! The value of x+y is 12

Make sure to read an explanation so you can understand the solution better.

Any questions about the answer and explanation can be asked through comments.

Step-by-step explanation:

We can simply solve the system of equations by substituting x = 3y in the first equation

[tex] \large{2x + 2y = 24} \\ \large{2(3y) + 2y = 24} \\ \large{6y + 2y = 24} \\ \large{8y = 24} \\ \large{y = 3}[/tex]

Therefore, the value of y is 3. Then we substitute the value of y in x = 3y.

[tex] \large{x = 3y} \\ \large{x = 3(3)} \\ \large{x = 9}[/tex]

Therefore, the value of x is 9.

Since you want to find x+y, simply add 9 and 3 as we get 12.

Therefore x+y = 12.
