Mathematics

Hoochie [10]4 years ago

Answer:

Step-by-step explanation:

2x + 4y = 6

4y = -2x + 6

y = -1/2x + 3/2.....slope = -1/2, y int = 3/2

x - 2y = 3

-2y = -x + 3

y = 1/2x - 3/2....slope = 1/2, y int = -3/2

different slopes, different y int's.....means one solution <==

Solve x2 + 4x – 4 = 0
Damm [24]

Answer:

Quadratic Equations! Yes!

Step-by-step explanation:

Now, there are three methods to solving this:

1.Quadratic Formula

2.Factoring

3. Completing the square

Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.

So, Quadratic Formula! To solve it using this method, we have to find x using this: x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}(the +- before the square root means it could be both positive or negative)

Where a, b are coefficients and c is a term(in a quadratic equation form: ax^{2} +bx+c=0)

So, we just have to input the stuff from our equation into the formula!

x=\frac{-4+-\sqrt{32} }{2}

Now, we can simplify the square root of 32 into 4 times the square root of 2

x=\frac{-4+-4\sqrt{2} }{2}

And, we can divide 2 from it all!

x=-2+-2\sqrt{2}

So, there you have it! The Answer is C, or 3.

Hope this helps!

colise has 2 vases of flowers that each hold 10 red and 5 yellow roses. Michelle has the same total number of roses but in 3 vas
Maslowich
So each of Colise vases have 15 roses in them so she has a total of 30 roses 20 red and 10 yellow. Michelle also has 30 roses but he has three vases, each with 6 red roses, 6 x 3 is 18 and 30 - 18 is 12, 12/3 is 4 so Michelle would have 4 yellow roses in each of her vases.

Solve the equation 36x^2 25=0
Anna71 [15]
Would assume it to be 36x² - 25 = 0

<span>36x² - 25 = 0
</span>
<span>(6x)² - 5</span>²<span> = 0</span>

(6x + 5)(6x - 5) = 0         By difference of two squares.

6x + 5 = 0           or         6x - 5 = 0

6x = -5                             6x = 5

x = -5/6                              x = 5/6

x = +5/6   or - 5/6
