Answer:

Axis of symmetry at $x=2$

Step-by-step explanation:

The graph of the function $f(x)= x^2 - 4x + 6$

To find axis of symmetry we use formula $x=\frac{-b}{2a}$

Given equation is in the form of

$y=ax^2+bx+c$

$a=1, b=-4, c=6$

Plug in the values in the formula

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

$x=\frac{-(-4)}{2(1)}$

$x=2$

Solve each equation by graphing the related function. If th equation has no real number solution, write no solution. X^2 + 7 = 0

Brrunno [24]

Answer:
The equation x² + 7 = 0 has no solution

Explanation:
1- using graph:
To solve the equation means graphically means to find the x-intercepts.
The attached image shows the graph of the given function.
We can note that there are no x-intercepts. This means that the given function has no real solutions

2- using algebra:
To solve the equation algebraically means to find the values of x that would make the equation equal to zero.
Solving the given equation, we would find that:
x² + 7 = 0
x² = -7
x = <span>± </span>√-7
The square root of a negative number will always give imaginary values. This means that the equation has no real solutions

Hope this helps :)

eff can paint 28 square feet every 30 minutes. Angela can paint 50 square feet every hour. Who can paint faster, and by how many

lisabon 2012 [21]

Guessing “eff” is Jeff ;)
28 sq feet/30 min = 56 sq feet/60 minutes

Angela
50 sq feet/60 min

So Jeff paints 6 square feet more per hour.

It costs a publishing company $0.55 to print one copy of a certain novel. This company paid $725,000 for the rights to the novel

Dmitrij [34]

Answer:

The correct answer is b. 116,900

The publishing company must sell 116,900 copies of the book to break even.

Step-by-step explanation:

Each book costs 0.55 to make and the company can sell it at 6.75, which means that the company earns 6.20 from each book, this is called the net value. If you divide the amount htat the company paid for the rights by the net value you can find the total number of copies that the company has to sell to break even.

# books = $725,000/$6.20 = 116935 or approximately 116900 copies of the book.

Determine the equation of each line with the following properties:

iris [78.8K]

Answer:

a) y =2/3 x + 7.

b) x = -1

c) y = -4/5 x - 1/5

d) y = -3/2 x + 5/2.

Step-by-step explanation:

a) Intercept form y = mx + b where m = 2/3 and b = 7

b) y can take any value but x is always -1.

c) Slope m = (-1-3)/ (1 - -4)

= -4/5

Using point-slope form where m = -4/5 and x1 y1 = 1 , -1:

y - y1 = m(x - x1)

y - -1 = -4/5(x - 1)

y + 1 = -4/5x + 4/5

y = -4/5 x - 1/5

d) The slope m of the line perpendicular to this line is:

-1 / 2/3

m = -3/2.

When x = -1 , y = 4 so using the slope intercept form of a line

y = mx + b

4 = -3/2 * -1 + b where b = the y-intercept.

4 = 3/2 + b

b = 4 - 3/2 = 5/2.

The equation is y = -3/2 x + 5/2.
