2x+4x=3x+1 how do you do this

1 answer:

6 0

On the left side of the equation, you have like terms : 2x and 4x
That means that you can combine them

2x+4x=3x+1

6x=3x+1

Now, since the 3x is on the other side of the equation, you have to perform the opposite operation by subtracting 3x on both sides of the equation:

The 3x's will cross out on the right side of the equation

3x-3x=0x=0

On the left side:

6x-3x=3x

SO, now the equation looks like:

3x=1

Now, to get x by itself, perform the opposite operation by dividing 3 on both sides of the equation:

The 3's will cross out on the left:

3x ÷ 3 = 1x = x

On the right:

1 ÷ 3 = 1/3

x=1/3

find the x-intercepts of the parabola with vertex(6,27) and y-intercept (0,-81). write answer in form (x1,y1)(x2,y2). if necessa

sergey [27]

The vertex form of the equation is:
y = a ( x - h )² + k
- 81 = a ( 0 - 6 )² + 27
- 81 = 36 a + 27
- 108 = 36 a
a = - 108 : 36
a = - 3
y = - 3 ( x - 6 )² + 27
y = - 3 ( x² - 12 x + 36 ) + 27
y = - 3 x² + 36 x - 108 + 27
y = - 3 x² + 36 x - 81
y = - 3 ( x² - 12 x + 27 )
x² - 12 x + 27 = 0
x² - 9 x - 3 x + 27 = 0
x ( x - 9 ) - 3 ( x - 9 ) = 0
( x - 9 ) ( x - 3 ) = 0
x 1 = 3, x 2 = 9
Answer:
The x-intercepts are ( 3, 0 ) and ( 9, 0 ).
