Your neighbor will let you take water from the well on his claim,
charging you $.05 a quart.

If 'x' is the number of quarts you take from his well on Tuesday, then
'y' is the amount of money you owe him before the sun goes down.

Which statement is true?

Nadusha1986 [10]

The correct statement is D.

Step-by-step explanation:

Given,

For backyard

Length = 5x-2

Width = 2x+4

For house

Length = 5x-2

Width = 4x-12

For driveway

Length = x+10

Width = 4x-12

To find the correct statement.

Formula

The area of a rectangle = Length × Width

So,

The area of the house and the driveway = (5x-2)(4x-12) + (x+10)(4x-12)

= (4x-12)(5x-2+x+10)

= (4x-12)(6x+8)

= $24x^{2} +32x-72x-96$

= $24x^{2} -40x-96$

So, the correct statement is D

You can cross check the other statements.

How do I solve this out??

GuDViN [60]

<h3>Answer:</h3>

(x, y) = (7, -5)

<h3>Step-by-step explanation:</h3>

It generally works well to follow directions.

The matrix of coefficients is ...

$\left[\begin{array}{cc}2&4\\-5&3\end{array}\right]$

Its inverse is the transpose of the cofactor matrix, divided by the determinant. That is ...

$\dfrac{1}{26}\left[\begin{array}{ccc}3&-4\\5&2\end{array}\right]$

So the solution is the product of this and the vector of constants [-6, -50]. That product is ...

... x = (3·(-6) +(-4)(-50))/26 = 7

... y = (5·(-6) +2·(-50))/26 = -5

The solution using inverse matrices is ...

... (x, y) = (7, -5)

A = P(1 + rt)

Where:

<span>· </span>A = Total Accrued Amount (principal + interest)

<span>· </span>P = Principal Amount

<span>· </span>I = Interest Amount

<span>· </span>r = Rate of Interest per year in decimal; r = R/100

<span>· </span>R = Rate of Interest per year as a percent; R = r * 100

<span>· </span>t = Time Period involved in months or years

A = 15,000(1+ 0.07(5))

A = 20,250 they acquired in total for 5 years

The yearly amount the get is 15,000 xx 0.07 = $ 1050 per year

So in the next 25 years addition of 1050x25 = $26250 they will get

Matt bought a home in 2001 and paid $150,000 for it. He sold the home for $450,000. How much of the profit on his home will be t

butalik [34]

Answer:

profit to be taxable will be $300,000

Step-by-step explanation:

Matt home cost = $150,000

Matt sold his home for = $450,000

so,

cost price will be $150,000

selling price will be $450,000

profit = selling price - cost price

profit = $450,000 - $150,000

profit = $300,000

hence the taxable amount for his home this year will be $300,000
