The answer is 3 because it is
LenaWriter [7]3 years ago
6 0

Answer and explanation:

The answer is actually -3. We already know f(x)/y is equal to 0, so the equation is then simplified to 0 = 2x - 6. You do inverse operation, so then -6 = 2x. Then -6 divided by 2 is -3. So -3 = x. Therefore, the zero of the function f(x) = 2x – 6 is -3.

Bee humming birds weigh only 0.0056 ounces. They haev t eat half their body weight every day to survive. How much food does a be
Advocard [28]

Answer:

The Humming bee need to eat 0.0028 ounces of food each day.

Step-by-step explanation:

Given:

Weight of the humming bee = 0.0056 ounces

We need to find amount of food humming bee should eat each day to survive.

Solution:

Now given that:

They have to eat half their body weight every day to survive.

So we can say that;

Amount of food humming bee needs to eat is half of the weight of the humming bee.

framing in equation form we get;

Amount of food humming bee needs to eat  = \frac{1}{2}\times 0.0056 =  0.0028\ ounces

Hence The Humming bee need to eat 0.0028 ounces of food each day.

What does the quadratic function f(x)=x^2-10x+9 look like when it is rewritten in the form f(x) = a (x-h) + k
Tatiana [17]

ANSWER

When f(x)=x^2-10x+9 is written in the form f(x)=a(x-h)^2+k, it looks like f(x)=(x-5)^2-16


EXPLANATION

To write  f(x)=x^2-10x+9 in the form f(x)=a(x-h)^2+k, we have to complete the squares.


We add and subtract half the coefficient of x square.


f(x)=x^2-10x+(-5)^2-(-5)^2+9


The first three terms of the function is now a perfect square.

f(x)=(x-5)^2-25+9

We now simplify rto obtain,

\Rightarrow f(x)=(x-5)^2-16
