Katen [24]

Answer:

y = 80 -40x

Step-by-step explanation:

The given equation shows the friend arrives at the restaurant (y=0) when x=2. That is, half the initial distance to the restaurant is covered in each hour of travel time.

If I take 2 hours to travel the 80 miles from my house, my distance will decrease at the rate of 40 miles per hour. My distance from the restaurant can be represented by ...

Write a quadratic function f whose zeros are 3 and 12.<br> f(x) = ?
ololo11 [35]

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

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

So, we can write as :

(x-3)(x-12)=0

Multiplying both factors,

(x-3)(x-12)=0\\\\x^2-12x-3x+36=0\\\\x^2-15x+36=0

So, the above equation is a quadratic function whose zeroes are 3 and 12.
