Commonly the horizontal axis represent the x-axis. So, you need the point that means x = 3 (positive 3), so, it is the point A.

What is 2 x 10 to the fourth power - 7 to the fourth power?

allochka39001 [22]

Answer:

10^4 = 10 x 10 x 10 x 10 = 10,000. 2 x 10,000 = 20,000. 7^4 = 7 x 7 x 7 x 7 = 2,401. 20,000 - 2,401 = 17,599.

the value of a car decreases at a constant rate. after 3 years the value of the car is 15,000. after 2 more years, the value of

Sladkaya [172]

Answer:

The linear equation is : y = -2000·x + 21000

Step-by-step explanation:

Let the time be denoted by x and the value of the car be denoted by y

After 3 years the value is 15000

$\implies x_1 = 3\text{ and }y_1 = 15000$

So, point is (3,15000)

After 2 years the value is 11000

$\implies x_2 = 2 + 3 = 5\text{ and }y_2 = 11000$

So, point is (5,11000)

Now, to find the linear equation we need to find the slope(m) of these two obtained points : (3,15000) and (5,11000)

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{11000-15000}{5-3}\\\\m=-2000$

So, the required linear equation will be :

$y-y_1=m\cdot (x-x_1)$

y -15000 = -2000·(x - 3)

⇒ y - 15000 = -2000·x + 6000

⇒ y = -2000·x + 21000

1, 3, 2, 2, 1, 3, 3, 1

Degger [83]

Answer:

(I only know part A. sorry) The mean is 2.

Step-by-step explanation:

To find the mean of data you have to add all of the numbers and then divide by the total number of numbers being added. (I hope that made sense)

So you have to do- 1+3+2+2+1+3+3+1=16 -and then- 16÷8=2 -so you're answer is 2.
