Answer:
The equation of the quadratic in standard form is:
![y=-2x^2-8x-2](https://tex.z-dn.net/?f=y%3D-2x%5E2-8x-2)
Step-by-step explanation:
Since they give us the information about where the vertex of the parabola is located, and one extra points where it passes through, we can use the general form of a quadratic in vertex form:
![y-y_v=a\,(x-x_v)^2](https://tex.z-dn.net/?f=y-y_v%3Da%5C%2C%28x-x_v%29%5E2)
where
is the location of the vertex (in our case the point (-2,6).
Therefore the equation above becomes:
![y-y_v=a\,(x-x_v)^2\\y-6=a\,(x-(-2))^2\\y-6=a\,(x+2)^2](https://tex.z-dn.net/?f=y-y_v%3Da%5C%2C%28x-x_v%29%5E2%5C%5Cy-6%3Da%5C%2C%28x-%28-2%29%29%5E2%5C%5Cy-6%3Da%5C%2C%28x%2B2%29%5E2)
Now,we can use the fact that the point (-4,-2) is also a point of the graph, to find the value of the parameter
:
![y-6=a\,(x+2)^2\\-2-6=a\,(-4+2)^2\\-8=a\,(-2)^2\\-8=a\,*4\\a=-2](https://tex.z-dn.net/?f=y-6%3Da%5C%2C%28x%2B2%29%5E2%5C%5C-2-6%3Da%5C%2C%28-4%2B2%29%5E2%5C%5C-8%3Da%5C%2C%28-2%29%5E2%5C%5C-8%3Da%5C%2C%2A4%5C%5Ca%3D-2)
Then, the equation of the quadratic with such characteristics becomes:
![y-6=-2\,(x+2)^2\\y-6=-2x^2-8x-8\\y=-2x^2-8x-2](https://tex.z-dn.net/?f=y-6%3D-2%5C%2C%28x%2B2%29%5E2%5C%5Cy-6%3D-2x%5E2-8x-8%5C%5Cy%3D-2x%5E2-8x-2)
which is the equation of the quadratic in standard form.
Answer:
28 students would vote for kim
Step-by-step explanation:
Well first you do 12/15 which would be 0.8
Now to find how many students in that class said they would vote for Kim for class president, we multiply 0.8 by 35 to get that 28 students said they would vote for kim
Answer:
x=26
y=9
Step-by-step explanation:
5x-17+3x-11=180
8x=180+17+11
8x=208
x=26
3(26)-11=78-11=67
2y+5=90-67
2y=90-67-5
2y=18
y=9
