(4s+5t)(4s-5t)

16s^2 - 20st + 20st - 25t^2

Combine like terms...

-20st + 20st = 0

The answer is:

16s^2 - 25t^2

A married couple filing their federal income tax return jointly had a taxable

julia-pushkina [17]

Answer:

The income will they have left over after paying their federal income tax is $64,850.00.

Step-by-step explanation:

Given:

A married couple filing their federal income tax return jointly had a taxable

income of $76,300.

Now, to find according to the table the income will they left over after paying their federal income tax.

So, as given in table:

The tax of the taxable income over $67,900 but not over $1,37,050 is $9,350 plus 25% of the amount over $67,900.

As, the taxable income $76,300 falls in to the above conditions.

Now, to calculate the tax:

$9350+25\%\ of\(76300-67900)$

$=9350+25\%\ of\ 8400$

$=9350+\frac{25}{100} \times 8400$

$=9350+0.25\times 8400$

$=9350+2100$

$=11450.$

Thus, the tax = $11450.

Now, deducting the tax from the taxable income:

$76300-11450\\=64850$

So, the amount left = $64,850.

Therefore, the income will they have left over after paying their federal income tax is $64,850.00.

Y = one-fourth x minus 6 be determined? Explain.

Luden [163]

Answer:

Step-by-step explanation:

For a given function f(x), we define the domain as the set of the possible inputs of the function and the range as the set of the outputs of the function.

We will see that both domain and range are the set of all real numbers.

D = (-∞, ∞)

R = (-∞, ∞)

Here we have the function:

The first thing we need to do is find the domain.

We start by assuming that the domain is the set of all real numbers and then we try to find some given values of x that cause some undefined operation, and then we remove these values of x from the domain.

Where this would be something like a zero in the denominator or something like that. We also could have specific restrictions to the domain that are applied in some specific cases (for example if x represents a length we should remove the negative values from the domain).

Here we can see that we do not have any indetermination, thus the domain is the set of all real numbers.

Now to study the range we need to see the general function, we can see that as x tends to negative infinity y will also tend to negative infinity, while when x tends to infinity y will also tend to infinity.

Then the range will also be the set of all real numbers.

a store sells for 25% off the regular price the regular price of a beach towel is 24.50 which expression represents the scale pr

UNO [17]

$24.5 \times 1.25 = 30.625$
Since you're adding on to the regular price, you can say it is 125% of the price. Or you can use the regular equation:
$(24.5 \times .25) + 24.5 = 30.625$
Since you're only finding 25% of 24.5, you have to add on 24.5 because you're paying for the beach towel and applying the sales tax.

Now, since cents are to the hundredths place, you have to round.
The final price would be $30.63
