<h3>Answer: 3 x 10^6</h3>

This is the number 3,000,000 aka 3 million

=======================================================

To find this answer, we divide the two values (large/small)

(9 x 10^12)/(3 x 10^6)

(9/3) x 10^(12-6)

3 x 10^6

We divided the stuff out front like normal (9/3 turns into 3) and we subtract the exponents when dividing the 10^12 over 10^6. The general rule is that

(a^b)/(a^c) = a^(b-c)

The result 3 x 10^6 is in scientific notation. It represents the number 3,000,000 aka 3 million. While 9 x 10^12 represents 9,000,000,000,000 which is the number 9 trillion.

If y = 4x – 1, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

Helga [31]

Hello!

To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.

y=4(0)-1
y=-1

So here, an ordered pair could be (0,-1)

We can try this again for different x-values.

y=4(1)-1
y=3

This gives us the ordered pair (1,3)

y=4(100)-1
y=399

This would give us the ordered pair (100,399)

I hope this helps!

On a coordinate plane, a parabola opens up. It goes through (negative 2, 4), has a vertex at (0.25, negative 6), and goes throug

Oksana_A [137]

Answer:

The function has two x-intercepts.

The vertex of the function is (one-quarter, negative 6 and one-eighth).

Step-by-step explanation:

Given that the vertex is located at (0.25, -6) and the parabola opens up, the function has two x-intercepts.

f(x) = 2x² - x - 6 has the following coefficients:

a = 2

b = -1

c = -6

x-coordinate of the vertex is:

x = -b/(2a)

x = 1/(2*2) = 1/4

y-coordinate of the vertex is:

f(1/4) = 2(1/4)² - 1/4 - 6 = -6 1/8
