Answer:
Step-by-step explanation:
x must be an even number from 0 to 9. So x can be
0 2 4 6 8
Answer:
All the intervals that contain the number are solution of the problem
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
-------> equation in vertex form
The vertex is the point
The x-coordinate of the vertex is
The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.
<h3>How to use inverse proportionality to determine building time of a wall</h3>
In this question we must use the definition of <em>inverse</em> proportionality, in which the number of workers (), no unit, is inversely proportional to the <em>building</em> time (), in days.
According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:
In this scenario, the wall can be built in 22 days.
