Water Tank A is being filled according to the formula, 3y=750x+300.
Darina [25.2K]

Answer: All the time.

Step-by-step explanation:

Here,

x= elapsed time

y = number of gallons of water in tank.

For tank A,

3y=750x+300

Divide both sides by 3, we get

y= 250x+100 ...(i)

For tank B,

4y=1000x+400

Divide both sides by 4, we get

y=250+100 ...(ii)

From (i) and (ii) it can be seen that both the function are same.

That means the amount of watre will be same for every value of x, where x ≥0

A book club charges a membership fee of $20 and then $12 for each book purchased. Write a function to represent the change, y, o
riadik2000 [5.3K]
It is y = 12x + 20.
You start with 20 as the y-intercept because that is the starting amount that you paid. The constant rate of change is 12 dollars per book. So, 12 time however many books written as 12x. Hope that helps! :)

You invested $7,000 into a money market account for 10 years at an annual interest rate of 3%. How much is the accrued interest?
steposvetlana [31]

The total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%.

<h3>What is invested amount?</h3>

An investment is a payment made to acquire the securities of other firms with the intention of making a profit.

We are assuming the interest will be compounded annually

\rm A = P(1+\dfrac{r}{n})^{nt}

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

We have:

P = $7000

r = 3% = 0.03

t = 10 years

n = 1

\rm A = 7000(1+\dfrac{0.03}{1})^{1\times10}

After calculating:

A = $9407.41

I = A - P = 9407.41 - 7000 = $2,407.41

Thus, the total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%.
