2x^2=4+6x<br> Show your work please
Furkat [3]

Answer: x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

Step-by-step explanation:

2x^2 = 4 + 6x

divide both sides by 2

x^2 = 2 + 3x

move expression to the left

x^2 - 2 - 3x = 0

reorder the terms

x^2 - 3x - 2 = 0

use the quadratic formula

x = - (-3) +- sqrt (-3)^2 - 4 x (-2) / 2 x 1

calculate

x = 3 +- sqrt 17 / 2

answer

x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

andrezito [222]

Answer:

3x+2y=315\\\\2x+4y=450

is the system of equations representing the situation.

Step-by-step explanation:

Given:

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2  haircuts and 4 hair dyes takes 450 minutes.

Now, to find the system of equations representing the situation.

<u><em>Let the number of haircuts be </em></u>x.<u><em /></u>

<u><em>Let the number of hair dyes be </em></u>y.<u><em /></u>

So, Alexandra can give 3 haircuts and 2 hair dyes in:

3x+2y=315.

Now, giving 2 haircuts and 4 hair dyes in:

2x+4y=450.

Therefore,

3x+2y=315\\\\2x+4y=450

is the system of equations representing the situation.
