Ling decides to sell cupcakes at the country fair. Her ingredients cost her about 25 cents per cupcake. Renting a booth costs $3

koban [17]

To find how many cupcakes Ling must sell to break even, you will create an equation where the functions are equal.

0.25x + 30 = 1x; then solve the equation for x, the number of cupcakes.

0.25x + 30 = 1x

-0.25x -0.25x

30 = 0.75x

30 30

x = 40

Ling will need to sell 40 cupcakes.

X² - 6x + 4 = 0 solve and show work. ...?

ycow [4]

The answer is 3 + √5 and 3 - √5.

This is quadratic equation: x² - 6x + 4 = 0
The general quadratic equation is ax² + bx + c = 0
Our equation can be rewritten: 1x² + (-6)x + 4 = 0
So, in our equation we have: a = 1, b = -6, c = 4

Now, x can be calculated using the formula: $x_{1,2}= \frac{-b+/- \sqrt{ b^{2}-4ac } }{2a}$
$x_{1,2} =\frac{-(-6)+/- \sqrt{ (-6)^{2}-4*1*4 } }{2*1} = \frac{6+/- \sqrt{36-16} }{2} = \frac{6+/- \sqrt{20} }{2} =\frac{6+/- \sqrt{4*5} }{2}= \\ 
=\frac{6+/- \sqrt{4}* \sqrt{5} }{2} =\frac{2*3+/- 2\sqrt{5} }{2}= \frac{2(3+/- \sqrt{5}) }{2} =3+/- \sqrt{5}$

From here:
$x_{1} =3+ \sqrt{5} \\ 
x_{2} =3- \sqrt{5}$
