What are the solutions of -x^2+4x=x-4
Stolb23 [73]

Answer:

x = -1 and x = 4

Step-by-step explanation:

Step 1:  Get everything to one side of the equation so it's set equal to zero..

-x² + 4x = x - 4  becomes...

  -x² + 3x + 4 = 0        (subtract x and add 4 to both sides)

    x² - 3x - 4 = 0  (divide both sides by -1, we want the x² term to be positive)

   (x - 4)(x + 1) = 0          (factor)

      so

x - 4 = 0,    then x = 4

and

x + 1 = 0,   then x = -1

Find the value of x for the given equation : 2 (x-1) - 6 =24​
olasank [31]

Answer:

x = 16

Step-by-step explanation:

2(x - 1) - 6 = 24 ( add 6 to both sides )

2(x - 1) = 30 ( divide both sides by 2 )

x - 1 = 15 ( add 1 to both sides )

x = 16

alice has eight good behavior stars and earns a new one each week. Mack has two good behavior stars and earns two new ones each
IRINA_888 [86]

Answer:

In 14 weeks will they have the same number of good behavior stars

Step-by-step explanation:

Let

x ----> the number of weeks

y ----> the number of good behavior stars

we know that

<em>Alice</em>

y=x+8 ----> equation A

<em>Mack</em>

y=2x+2 ----> equation B

To find out in how many weeks will they have the same number of good behavior stars, equate equation A and equation B

2x+2=x+8

Solve for x

2x-x=8-2

x=6\ weeks

<u><em>Verify</em></u>

For x=6 weeks

<em>Alice</em>

y=(6)+8=14\ stars

<em>Mack</em>

y=2(6)+2=14\ stars

therefore

In 14 weeks will they have the same number of good behavior stars
