The valley in California has an elevation of feet "below sea level".
Below sea level means below 0 feet, so it'd have -5 feet
The one in Arizona would be lower than it, so the elevation will definitely be -9 feet
Answer:
The answer is 18
Step-by-step explanation:
p+q/4=12+24/4
Since we evaluate the division first: 12+6=18
Thus, the answer is 18
D) x^2 + 7x + 12 is the answer
Answer:
Step-by-step explanation:
Its 8
A function is described as a quadratic function if the highest power of the variables of the function is 2.
For
![8 - 5x = 4(3x - 1)=12x-4 \\ \\ 12x+5x-8-4=0 \\ \\ 17x-12=0](https://tex.z-dn.net/?f=8%20-%205x%20%3D%204%283x%20-%201%29%3D12x-4%20%5C%5C%20%20%5C%5C%2012x%2B5x-8-4%3D0%20%5C%5C%20%20%5C%5C%2017x-12%3D0)
The highest power of x is 1, hence, the function is not a quadratic function.
For
![(4a + 2)(2a - 1) + 1 = 0 \\ \\ 8a^2-4a+4a-2+1=0 \\ \\ 8a^2-1=0](https://tex.z-dn.net/?f=%284a%20%2B%202%29%282a%20-%201%29%20%2B%201%20%3D%200%20%5C%5C%20%20%5C%5C%208a%5E2-4a%2B4a-2%2B1%3D0%20%5C%5C%20%20%5C%5C%208a%5E2-1%3D0)
The highest power of a is 2, hence, the function is a quadratic function.
For
![2y + 2(3y - 5) = 0 \\ \\ 2y+6y-10=0 \\ \\ 8y-10=0](https://tex.z-dn.net/?f=2y%20%2B%202%283y%20-%205%29%20%3D%200%20%5C%5C%20%20%5C%5C%202y%2B6y-10%3D0%20%5C%5C%20%20%5C%5C%208y-10%3D0)
The highest power of y is 1, hence, the function is not a quadratic function.
For
![2b(b - 7) + b = 0 \\ \\ 2b^2-14b+b=0 \\ \\ 2b^2-13b=0](https://tex.z-dn.net/?f=2b%28b%20-%207%29%20%2B%20b%20%3D%200%20%5C%5C%20%20%5C%5C%202b%5E2-14b%2Bb%3D0%20%5C%5C%20%20%5C%5C%202b%5E2-13b%3D0)
The highest power of b is 2, hence, the function is a quadratic function.
Therefore, the quadratic functions are (4a + 2)(2a - 1) + 1 = 0 and <span>2b(b - 7) + b = 0</span>
