so, this is a quadratic equation, meaning two solutions, and we have a factored form of it, meaning you can get the solutions by simply zeroing out the f(x).
so the zeros/solutions are at x = 3 and x = -11, now, bearing in mind the vertex will be half-way between those two, checking the number line, that midpoint will be at x = -4, so the vertex is right there, well, what's f(x) when x = -4?
Answer:
<u>$4</u> is spent on a big pail and <u>$2</u> is spent on a small pail.
Step-by-step explanation:
Given:
10$ is spent on 2 big pails and 1 small one.
A small pail cost half as much as each big one.
Now, to find the amount spent on a big pail and on a small pail.
Let the cost of a big pail be
And the cost of small pail be
As given, there are 2 big pails.
And the total money spent = $10.
According to question:
<em>Multiplying both sides by 2 we get:</em>
<em>Dividing both sides by 5 we get:</em>
<em>The cost of a big pail</em> = $4.
<em>So, the cost of a small pail</em> =
Therefore, $4 is spent on a big pail and $2 is spent on a small pail.
