a) Is this a proportional relationship?

b) If this is a proportional relationship, what is the constant? Write N/A if it is not proportional.

c) If this is a proportional relationship, write a direct proportion equation. Write N/A if it isnot proportional.

Answers

yesssssssssssassssssss

a) Yes, This is a proportional relationship.

b) The value of constant is, 1/3.

c) The direct proportion equation is,

⇒ y = 1/3x

Where, y represent the cost and x represent the number of days.

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

We have to given that;

The relation is,

X-number of days      Y- cost

6                                    2

9                                    3

24                                  8

3                                    1

Let number of days = x

And, Cost = y

So, By definition of proportional, we have;

⇒ y = kx

Where, k is constant of proportionality.

Now, By the given relation, we get;

⇒ 2 = k × 6

⇒ k = 2/6

⇒ k = 1/3

And, y = kx

⇒ 3 = k × 9

⇒ k = 3/9

⇒ k = 1/3

Hence, The given relation is in proportion.

And, The value of constant of proportionality = 1/3

Thus, The direct proportion equation is,

⇒ y = 1/3x

Where, y represent the cost and x represent the number of days.

One Month Yareli made 3 withdrawals for $20 and 1 withdrawal for $80 from her account. How did the withdrawals change the amount in her account?

Answers

Answer:

$140

Step-by-step explanation:

3*20=60

80+60=140

Answer:

The withdrawals would be subtracted away from the account

Step-by-step explanation:

I will use x, as the unknown value for the amount of money left in Yareli's account.

Yareli made a total of 4 withdrawals, all adding up to the sum of $140 withdrawn from the account. So, in the equation, it would kind of look like this:

x - $140.
