Answer:

x = 2 & - 2

Step-by-step explanation:

We have to find the value of x from the given equation.

x²-4=0 is a quadratic equation, so it will have two values.

Step: Write the equation in simplest form.

x²-4=0

Step: Solve the problem by spiltting method.

x² - 4 = 0
x² - (2)² = 0

Step: Solve the problem with using algebraic formula.

x² - 2² = 0
(x - 2)(x + 2) = 0

Step : We have used a²-b² to solve the problem.

(x - 2)(x + 2) = 0
(x - 2)(x + 2) = 0
(x - 2)=0 or (x + 2) = 0
x = 2 & - 2

Therefore, the possible values of x are 2 & - 2.

Papessa [141]

Answer:

A (Wrong)

B (Correct)

C (Wrong)

D (Wrong)

Step-by-step explanation:

The y-intercept is $-2$ because the line intercepts are touch the y-intercept at $-2$ . Further more find two point on the line that has whole number in the order pair. Which is $-\frac{3}{2}$ meaning that it takes the point to move $3$ units down and to $2$ right.

How do you rearrange the equation (2x) /(4pi) +((1-x) /2) =0 to solve for x?

USPshnik [31]

$\frac{2x}{4 \pi } + \frac{1-x}{2} =0 \\ 
 \frac{x}{2 \pi } + \frac{1-x}{2} = 0$
Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )
