The answer is (-21, 13) for The second endpoint.
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 + 1)/2 = -10
Kx + 1 = -20
Kx = -21
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + 7)/2 = 10
Ky + 7 = 20
Ky = 13
This gives us the final point of (-21, 13)
Answer:
x = ± 6
Step-by-step explanation:
Given
x² - 72 = 0 ( add 72 to both sides )
x² = 72 ( take the square root of both sides )
x = ± 
= ± 
= ± 6
Answer:
6x² - 19x + 10
Step-by-step explanation:
Given
(3x - 2)(2x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(2x - 5) - 2(2x - 5) ← distribute both parenthesis
= 6x² - 15x - 4x + 10 ← collect like terms
= 6x² - 19x + 10
I will help u but you need to tell me the problem
3/8 divided by 5/8 = 3/5
hope this helps :D
