-5n-8(1+7n)=8
Let's simplify everything.
-5n-8-56n=8
Put the variables on one side and the numbers on the other.
-5n-56n=8+8
Combine like terms.
-61n=16
n=-16/61
Hope I helped! :)
Step-by-step explanation:
8x + x² - 2y + y² - 64 = 0
(x + 4)² + (y - 1)² - 81 = 0
(x + 4)² + (y - 1)² = 81
Hencr the center is (-4,1) and the radius is 9.
SOLUTION;
![\sqrt[]{-36}\text{ = }\sqrt[]{(36)(-1)}\text{ = }\sqrt[]{36}\text{ x }\sqrt[]{-1\text{ }}\text{ = 6i}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B-36%7D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B%2836%29%28-1%29%7D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B36%7D%5Ctext%7B%20x%20%7D%5Csqrt%5B%5D%7B-1%5Ctext%7B%20%7D%7D%5Ctext%7B%20%3D%206i%7D)
Recall that the square root of the negative one is "i" meaning that it is a complex number and not a real number.
Find the change in the y coordinates
7-5=2
Find the change in the x coordinates
1--3 or 1+3= 4
Divide the changes in the y and x coordinates
2/4= 1/2
The slope is 1/2. Hope this helps!
