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.
Ok, so assuming you know what the slope of -1 looks like
a bit like \ except more diagonal
you look for point (4,-2), then you draw the -1 slope from it
it should cross through points (5,-3) and (3,-1)
The answer is (9, -9) for The second midpoint.
Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Kx + Lx)/2 = Mx
(Kx + 5)/2 = 7
Kx + 5 = 14
Kx = 9
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + -3)/2 = -6
Ky + -3 = -12
Ky = -9
This gives us the final point of (9, -9)
