Hi there! The answer is A.

$t = 2(s + 2)$
To get a proper idea of the type of function this formula represents we work out the parenthesis.

Working out the parenthesis can for instance be done using rainbow technique.
$t = 2s + 4$

We can now see sinilarities between this function an the general function of a line in slope intercept form
$y = mx + n$

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.

Whats the greatest ten you can multiply by 19 to get close to but not go over 684

USPshnik [31]

Answer:

The desired expression is 19 x (3 tens) = 19 x 30 = 570

So, the greatest ten = 3 (tens)

Step-by-step explanation:

Let us check each tens.

19 x (1 ten) = 19 x 10 = 190

19 x (2 tens) = 19 x 20 = 380

19 x (3 tens) = 19 x 30 = 570

19 x (4 tens) = 19 x 40 = 760

But, here 760 is OVER the given term 684.

and 570 is the nearest value to the value 684.

So, the desired expression is 19 x (3 tens) = 19 x 30 = 570

A boat costs $19,200 and decreases in value by 12% per year. How much will the boat be worth after 5 years?

zhannawk [14.2K]

<span>If it decreases by 12 percent, you do 19,200x.12 which is 2,304. You subtract that from 19,200 which is 16,896. You multiply that by .12 which is 2,027.52 and subtract that from 16,896 which is 14,868.42. You do that three more times and there's your answer.

State whether the slope of the line is positive, negative, zero, or undefined.

Rudiy27

The slope of the line is equal to $\tan \alpha,$ where angle $\alpha$ is angle of line incline to the positive x-direction.

When $\alpha$ is acute, then slope is positive;
When $\alpha$ is obtuse, then slope is negative;
When $\alpha$ is right, then slope is undefined;
When $\alpha$ is zero, then slope is equal to 0.

In your case angle of inclination is obtuse and slope is negative.

Answer: correct choice is B
