Arezo borrowed $2,500 from her grandfather. This graph shows the balance remaining on Arezo’s debt after she makes each payment. Using this graph, how much will she owe after 4 payments?

Answers

Answer:

She will owe $500 after 4 payments.

Step-by-step explanation:

With the help of graph

Number of payments (x) Balance remaining(y)

0 2500

1 2000

2 1500

Since it is linear function .

So, we will use two point slope form to find the equation for the given situation.

$y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)$ ----A

$(x_1,y_1)=(0,2500)$

$(x_2,y_2)=(1,2000)$

Substitute the values in A

$y-2500=(2000-2500)/(1-0)(x-0)$

$y-2500=-500x$

$y=-500x+2500$

Where x is the number of payments

y is the remaining payment

This equation represents the given situation.

So, to find the amount remaining after 4 payments .Substitute x =4

$y=-500(4)+2500$

$y=-2000+2500$

$y=500$

Hence she will owe $500 after 4 payments.

Answer:

She will owe $500

>
=

Answers

Answer:

4/10 = 14/35

Step-by-step explanation:

We need to compare 4/10 with 14/35

4/10=2/5

14/35=2×7/(5×7)=2/5

Since we have 2/5 on both sides, these fractions are equal.

Does this table represent a function, why or why not?

Answers

Answer:

a) No, because one x-value corresponds to two different y-values.

Step-by-step explanation:

Let's find the coordinates from the table values.

(2, 1), (3,4), (3, 3), (4, 2), (5, 5)

Here the input 3 has two outputs 4 and 3

3 is associated with two numbers 4 and 3.

Therefore, it is not a function.

Answer: a) No, because one x-value corresponds to two different y-values.

Hope you will understood the concept.

Thank you.

Answer:

Choice A is correct.

Step-by-step explanation:

We have ordered pair in the table:

(2,1) (3,4) (3,3) (4,2) (5,5)

We have to explain is it a function or not ?

Function is a rule that gives each input a single output.

It is not a function because one x value correspond to two different y values.

It is shown from the table that the input 3 has two different output values that is 4 and 3.

Input 3 has two outputs 4 and 3.

Choice A is correct.

What is the answer to -5 + (-26)

Answers

Answer: -31

Step-by-step explanation:

To solve this, we must bear in mind that positive multiplied by negative is negative

Therefore, -5 + (-26)

= -5 - 26....negative and negative, we add the values.

= -31

How can you use the Pythagorean Theorem to solve real-world problems?You can use the Pythagorean Theorem to find missing ________ (angles or lengths) in objects that are_________. ( squares, right triangles, or equilateral Triangles)

Answers

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

What is Pythagorean Theorem?

The Pythagorean Theorem is a mathematical principle that relates to right triangles. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

By rearranging the formula, you can solve for the missing length when given the lengths of the other two sides.

This can be applied to real-world problems involving measurements of objects or distances, such as determining the length of a ladder needed to reach a certain height on a wall or calculating the distance between two points on a map.
