Answer:
what set can you show a picture?
Step-by-step explanation:
Answer:
C. 9
Step-by-step explanation:
y = -4x^2 + 2kx
subtitute 3:
y = -4(9)^2 + 2k(9)
y = -4(81) + 18k
let y = 0
=> 0 = -324 + 18k
=> k = 324/18 = 9
this is my calculations hope it helps
ANSWER
![y \leqslant - 2x - 2](https://tex.z-dn.net/?f=y%20%5Cleqslant%20%20%20-%202x%20-%202)
EXPLANATION
The boundary line passes through (-2,2) and (0,-2).
The slope of this line is
![m = \frac{ - 2 - 2}{0 - - 2}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B%20-%202%20-%202%7D%7B0%20-%20%20-%202%7D%20)
![m = \frac{ - 4}{2} = - 2](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B%20-%204%7D%7B2%7D%20%20%3D%20%20-%202)
The y-intercept is , c=-2.
The slope-intercept form of this line is given by;
![y = mx + c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20c)
We substitute values to obtain;
![y = - 2x - 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%202x%20-%202)
Since the lower half-plane is shaded the required inequality is
![y \leqslant - 2x - 2](https://tex.z-dn.net/?f=y%20%5Cleqslant%20%20%20-%202x%20-%202)
