Answer:

(x-2 )( x + 1) = (-2 - c)

Step-by-step explanation:

C= - 1 = -x

We cna either multiply x and c until we find HCM before imputing x value and c value that is unknown variable.

To find that we can say x = the average of 1000 + $800 = $900 and work out the difference between the two.

We can use a new variable for half that difference to ensure we add or subtract to find the value 1000 or -1000 again.

So that $1000 - $847 = $153 half this difference is 2/3y so that 4/3 = $153 and 1/3 = 33.333 as we are working with 3 numbers then 1/3 or 2/3 for example could show a debit;

Balance of each 1000 would look like

2/3y + x + c

= c + xy - y1/3  

to show smaller amounts for the last 2 debits.

In a certain state, there are currently 5,902,060 acres of farmland. This area is decreasing at a rate of 4.3% every year. Selec
Luba_88 [7]

Answer:

y=5,902,060*(.957)^t

Step-by-step explanation:

Since the original amount would be decreasing and it's an exponential one, hence the "every year", we can determine that it's an exponential decay equation.

The exponential delay equation is y=A*(1-r)^t. The y is the remaining amount, A is the original amount, r is the rate in decimal form, and t is for years. "1-r" is for decreasing rates and "1+r" is for increasing rates.

First thing we need to do is turn the rate, 4.3%, from a percentage to a decimal. You can do this by moving the decimal two places to the right, which gives you 0.043.

Now plug the numbers into the equation.

y=5,902,060*(1-0.043)^t

Simplify what's inside the parenthesis and get your final equation.

y=5,902,060*(.957)^t

Find a solution to the linear equation y equals 8x-32
Lerok [7]

Answer:

(4, 0).

Step-by-step explanation:

y = 8x - 32

There are many solutions that we can choose from, since any set of coordinates that fit in the equation counts as a solution.

We can have (0, -32), (1, -24), (2, -16), (3, -8), (4, 0), and many more.

Hope this helps!
