Rewrite the equation 2x+6x^(2)-1=3x^(2) in standard form and identify a, b, and c.

Fed [463]

Hi there!

$2x + 6 {x}^{2} - 1 = 3 {x}^{2}$
First subtract 3x^2 from both sides.

$2x + 3 {x}^{2} - 1 = 0$
Now rearrange the equation.

$3 {x}^{2} + 2x - 1 = 0$
Finally we can see our answer.

$a = 3$
$b = 2$
$c = - 1$

Which is NOT a true statement?

rusak2 [61]

Answer:

option 4

Step-by-step explanation:

|a| represents Absolute value, it is the distance from zero that a number is on the number line. And we know distance cannot be negative.

So,

$|a| = a$

$|-a| = a\\\\| \frac{-a}{b}| = \frac{a}{b}\\\\|\frac{a}{-b}| = \frac{a}{b}$

4x - 7 (2 - x) = 3x + 2

juin [17]

Answer:

x=2

Step-by-step explanation:

4x−7(2−x)=3x+2

4x+(−7)(2)+(−7)(−x)=3x+2(Distribute)

4x+−14+7x=3x+2

(4x+7x)+(−14)=3x+2(Combine Like Terms)

11x+−14=3x+2

11x−14=3x+2

Step 2: Subtract 3x from both sides.

11x−14−3x=3x+2−3x

8x−14=2

Step 3: Add 14 to both sides.

8x−14+14=2+14

8x=16

Step 4: Divide both sides by 8.

x=2
