Answer:
The above equation is a quadratic function whose zeroes are 3 and 12.
Step-by-step explanation:
The general quadratic equation is given by :
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
It is given that, the zeroes of a quadratic function are 3 and 12. It means they must be factors of it such that,
![(x-3)=0\\\\(x-12)=0](https://tex.z-dn.net/?f=%28x-3%29%3D0%5C%5C%5C%5C%28x-12%29%3D0)
So, we can write as :
![(x-3)(x-12)=0](https://tex.z-dn.net/?f=%28x-3%29%28x-12%29%3D0)
Multiplying both factors,
![(x-3)(x-12)=0\\\\x^2-12x-3x+36=0\\\\x^2-15x+36=0](https://tex.z-dn.net/?f=%28x-3%29%28x-12%29%3D0%5C%5C%5C%5Cx%5E2-12x-3x%2B36%3D0%5C%5C%5C%5Cx%5E2-15x%2B36%3D0)
So, the above equation is a quadratic function whose zeroes are 3 and 12.
Answer: Angle J = 33.5°, angle K = 23.2°, angle L = 123.2°
Step-by-step explanation: i did the quiz and got it correct :D
Step 1: to solve this equation first subtract 4.9 from both sides.
w + 4.9 - 4.9 = 6.88 - 4.9
When you reduce that your answer should be w = 1.92
Therefore the weight of ingredients other than granola in Miranda's trail mix is 1.92

Step-by-step explanation:
hello :
the system is : y=−3x−1
y=x²−3x+4
means: x²−3x+4= −3x−1
x² = -5 no real solution because : x² ≥ 0
