SOMEONE HELP ????<br><br> Select steps that could be used to solve the equation 1+ 3x = -x+4
Alex

Answer:

a) add x , subtract 1 and divide by 4

The solution of given equation x = \frac{3}{4}

<u>Step-by-step explanation:</u>

Given equation  1+3 x  = -x +4

                <em>  Add 'x' on both sides , we get</em>

                     1 + 3 x + x = - x + x +4

                     1 + 4 x  = 4

      <em>  Subtract '1' on both sides , we get</em>

<em>                     1+4 x -1 = 4 -1</em>

                         4 x = 3

<em>       Dividing '4' on both sides, we get</em>

                          \frac{4x}{4} = \frac{3}{4}

                          x = \frac{3}{4}

<u><em>Final answer</em></u>:-

<em>The solution of given equation </em>x = \frac{3}{4}<em></em>

ABC is similar to DEF. Find x.
san4es73 [151]
<h3>Answer:  25</h3>

Through using the pythagorean theorem, you should find the hypotenuse of the smaller triangle to be 10 units. Therefore, the perimeter of the smaller triangle is 6+8+10 = 24 units.

The perimeter of the larger triangle is 60 units. The ratio here is 24:60 = 2:5

Meaning that the larger perimeter is 5/2 = 2.5 times that of the smaller.

We apply this scale factor 2.5 to the smaller hypotenuse 10 to jump to 2.5*10 = 25, which is the length of the larger hypotenuse.

Can someone explain how to convert a quadratic function in standard form to vertex form using the "complete the square" method?
Arisa [49]

The required steps are explained below to convert the quadratic function into a perfect square.

<h3>What is the parabola?</h3>

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

Let the quadratic function be y = ax² + bx + c.

The first step is to take common the coefficient of x². We have

\rm y = a \left (x^2 + \dfrac{b}{a}x \right) + c

Add and subtract the half of the square the coefficient of x,

\rm y = a \left (x^2 + \dfrac{b}{a}x + \dfrac{b^2}{4a^2} \right) - a \times \dfrac{b^2}{4a^2} + c

Then we have

\rm y = a \left (x + \dfrac{b}{a} \right)^2 - \dfrac{b^2}{4a} + c

These are the required step to get the perfect square of the quadratic function.

More about the parabola link is given below.
