Hi again!
2x + y > 8
The correct answer is option D
-------------------------------------------
Honestly I don't think we can solve the equation to find the answer. What we can do is to find the boundary line. (I think you know what that is) After that, shading the appropriate area.
y > -2x + 8
Again, credit to my beautiful graphing calculator. Here is how it looks like.
Answer:
The number is 7.
Step-by-step explanation:
The unknown number: x
9 (x + 7) = 126
Using the distributive property, 9x + 63 = 126
9x = 63
x = 7
Answer:
Slope - intercept form ![y = \frac{14}{3} x + 34](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B14%7D%7B3%7D%20x%20%20%2B%2034)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given points are ( -9 ,-8 ) and (-6,6)
slope of given two points
![m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{6-(-8)}{-6-(-9)} = \frac{14}{3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_%7B2%7D%20-y_%7B1%7D%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D%20%3D%20%5Cfrac%7B6-%28-8%29%7D%7B-6-%28-9%29%7D%20%3D%20%5Cfrac%7B14%7D%7B3%7D)
The equation of the straight line passing through the points and having slope
![y - y_{1} = m ( x - x_{1} )](https://tex.z-dn.net/?f=y%20-%20y_%7B1%7D%20%3D%20m%20%28%20x%20-%20x_%7B1%7D%20%29)
![y - (-8) = \frac{14}{3} ( x - (-9) )](https://tex.z-dn.net/?f=y%20-%20%28-8%29%20%3D%20%5Cfrac%7B14%7D%7B3%7D%20%20%28%20x%20-%20%28-9%29%20%29)
3 y + 2 4 = 14 x + 126
3 y = 14 x + 126 - 24
3 y = 14 x + 102
![y = \frac{14}{3} + \frac{102}{3}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B14%7D%7B3%7D%20%2B%20%5Cfrac%7B102%7D%7B3%7D)
![y = \frac{14}{3} x + 34](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B14%7D%7B3%7D%20x%20%20%2B%2034)
Slope - intercept form y= mx +C
Slope - intercept form ![y = \frac{14}{3} x + 34](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B14%7D%7B3%7D%20x%20%20%2B%2034)
