Answer:

Open Circle from 3 to -10

Step-by-step explanation:

M is less than 3 in this equation (because the "mouth" is eating the bigger variable, 3) so the graph goes from 3 and down. The circle is open because the symbol is (<) I think of it like this: the closed circle has more to it because you have to color it in. The (≥) symbol also has more to it because it has a line below it. So maybe use that to think about. Have a nice day!

Answer:

Part A) The correct Expression : (1.05)(190)(0.8)

=> The error of Joel was that instead of adding the sales tax, he subtracted it.

Part B) $159.60

Step-by-step explanation:

Part A:

To calculate the computer cost, we need to find out the selling price first.

There's a discount of 20% so the selling price will be 100% - 20% = 80% =>80/100 = 0.8

So, We'll multiply the cost price by 0.8

=> (190)(0.8)

But, there is a sales tax of 5%

So, the selling price with cost price will be:

=> 100% + 5% = 105% => 105/100 = 1.05 (We'll multiply this too with the first equation that we made above)

So, the expression will be:

=> (1.05)(190)(0.8)

The error of Joel was that instead of adding the sales tax, he subtracted it.

Part B)

Joel will pay for the tablet:

=> (1.05)(190)(0.8) [We used the above expression]

=> $159.60

Solve the system of equations {3x-y=10, -x y=12} for Y

Novosadov [1.4K]

3x - y = 10 . . . (1)
-x + y = 12 . . . (2)

(1) + (2) => 2x = 22 => x = 22/2 = 11

From 2, -11 + y = 12 => y = 12 + 11 = 23

You deposit $10,000 into a bank account at 2% annual interest. How long will it take for the $10,000 to compound to $30,000?

Rama09 [41]

Answer: time = 55.48 years

Explanation:

Given:

Principal amount = $10000

Interest rate = 2% p.a

Amount = $30000

We can evaluate the time taken using the following formula:

$Amount=Principal(1+\frac{r}{100})^{t}$

$30000 = 10000\times(1+\frac{2}{100})^{t}$

Solving the above equation, we get

$1.02^{t} = 3$

Now taking log on both sides, we get;

$t\ log(1.02) = log(3)$

time = 55.48 years
