What is the equation of the axis of symmetry of the graph of y=ax^2+bx+c

Phantasy [73]

Answer:

$x=-\frac{b}{2a}$

Step-by-step explanation:

we know that

The quadratic equation $y=ax^{2}+bx+c$ is a vertical parabola

The axis of symmetry in a vertical parabola is a vertical line

The equation of the axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex

The x-coordinate of the vertex is equal to the formula

$x=-\frac{b}{2a}$

therefore

the equation of the axis of symmetry is equal to $x=-\frac{b}{2a}$

Mr. Fernandez uses 7 boards that are 4 feet long and 6 inches wide to make on bookshelf. If he buys lumber in lengths of 8 feet

True [87]

Bookshelf =7boards each
Lumber=4 boards each
He wants to make 5 bookshelves total
5x7=35
So he needs 35 boards
And each lumber makes 4 boards
So what number times 4 is equal to or more than 35?

9times 4 is 36

So he needs 9 pieces of lumber to make 5 bookshelves.

Good luck with your work! Brainliest would be appreciated :)

The line of best fit for the information in this graph is:

f(x) = 200x + 100.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v) are given as follows:

(2, 500), (3, 700), (4, 900), (5, 110)

Hence, inserting these points into a calculator, the equation is given by:

f(x) = 200x + 100.
