(x^2) - 16 / x+4 = (x-4)(x+4) / (x+4) = x-4, x not equal to -4
D is the answer.
Answer:
C
Step-by-step explanation:
To write the equation of a line use the point slope form of a line substituting m = -1/2 and the point (-2,-3).
![y -y_1 = m(x-x_1)\\y --3=-\frac{1}{2}(x--2)\\y+3 = -\frac{1}{2}(x+2)](https://tex.z-dn.net/?f=y%20-y_1%20%3D%20m%28x-x_1%29%5C%5Cy%20--3%3D-%5Cfrac%7B1%7D%7B2%7D%28x--2%29%5C%5Cy%2B3%20%3D%20-%5Cfrac%7B1%7D%7B2%7D%28x%2B2%29)
Convert to standard form by applying the distributive property and rearranging the terms.
![y + 3 = -\frac{1}{2}(x+2)\\y+3 = -\frac{1}{2}x -1\\2y + 6 = -x -2\\x+2y + 6 = -2\\x + 2y = -8](https://tex.z-dn.net/?f=y%20%2B%203%20%3D%20-%5Cfrac%7B1%7D%7B2%7D%28x%2B2%29%5C%5Cy%2B3%20%3D%20-%5Cfrac%7B1%7D%7B2%7Dx%20-1%5C%5C2y%20%2B%206%20%3D%20-x%20-2%5C%5Cx%2B2y%20%2B%206%20%3D%20-2%5C%5Cx%20%2B%202y%20%3D%20-8)
The equation x +2y = -8 is the same equation as 4y + 2x = -16 just doubled----> 2x + 4y = -16
Hi there!
The answer would be A. m = 45h
Hope this helps
Answer:
1
Step-by-step explanation:
identify two points on the graph:
1. (0, 4)
2. (-2, 2)
use slope formula: (y² - y¹) / (x² - x¹)
1. (2 - 4) / (-2 - 0) = -2 / -2 = 1
slope = 1
5x-3=y 6x-3=y
x=1 x=1
51-3=y 61-3=y
51=5 61=6
5-3=y 6-3=y
2 3
y=2 y=3
