HELPPPP what do I do exactly ?

Answer:

Step-by-step explanation:

Note that the squaring function and the square root function are inverses of one another. If we make a list of perfect squares, we get {1, 4, 9, 16, 25, ...}. Then the square roots of these numbers are {1, 2, 3, 4, 5, ... }.

Continue making a table of values to plot. The first row has x=0, y=0; this reflects that the sqrt of 0 is 0.

Fill the first (x-) column with perfect squares and the second (y-) column with the square roots of these perfect squares:

x y

0 0

1 1

4 2

9 3

and so on.

Now plot the following on the graph: (1,1), (4,2), (9,3), ....

Starting at (0,0) and moving to the right (indicating increases in x), plot these points. (You'll soon run out of room.) Draw a smooth curve from (0,0) to connect these points. The result is a graph of the square root function.

The domain of this function is "the set of all real numbers ≥0" and the range is the same: "the set of all real numbers ≥0"

At the end of year 1, Boller Co. had an ending balance in allowance for uncollectible accounts of $30,000. During year 2, Boller

Masja [62]

Answer:

$34,000

Step-by-step explanation:

First they had 30,000

Then wrote off 40,000

So balance is 30,000 - 40,000 = -10,000

Now, they want 8% of 300,000 as uncollectible. So that would be

0.08 * 300,000 = 24,000

Thus, to bring the balance to 24,000 [balance is -10,000], how much would they need to add?? Let it be x:

-10,000 + x = 24,000

x = 24,000 + 10,000 = $34,000

Urgent please help quick!!!

Answer:

$x=-1\\y=-1$

Step-by-step explanation:

$5x+5y=-10\\3x-7y=4$

Let's solve the first equation for either x or y. I'll do it for x.

$5x+5y=-10$

Begin by subtracting 5y.

$5x=-5y-10$

Now divide by 5.

$x=\frac{-5y}{5}-\frac{10}{5}$

Simplify:

$x=-y-2$

Now substitute x in the second equation for this value.

$3x-7y=4\\3(-y-2)-7y=4$

Distribute;

$-3y-6-7y=4$

Add 6

$-3y-7y=4+6$

Combine like terms;

$-10y=10$

Divide by -10.

$y=\frac{10}{-10}\\ y=-1$

-----------------------------------------------------------------------------------------------------------

Take this value of y and replace it in the first equation to find the value of x.

$5x+5y=-10\\5x+5(-1)=-10\\5x-5=-10\\5x=-10+5\\5x=-5\\x=\frac{-5}{5}\\ x=-1$
