We're given a parabola

$y=x^2-4$

and a line

$y = 2x+b$

The zeros of the parabola are

$0=x^2-4$

$4=x^2$

$x=\pm 2$

We see that (-2,0) is on the line as well:

$y = 2x+b$

$0 = 2(-2)+b$

$b=4$

What is the solution to this system if equations

Inessa05 [86]

solution is (x, y ) → (- 1, 4 )

y + 2x = 2 → (1)

y + 4x = 0 → (2)

subtract equation (1) from (2) to eliminate term in y

(y - y ) + (4x - 2x ) = (0 - 2 )

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

x = - 1

substitute x = - 1 in either (1) or (2) and solve for y

(1) → y - 2 = 2 ( add 2 to both sides )

y = 4

solution is (x, y ) → (- 1, 4 )

If 1/2 is subtracted from four times the reciprocal of a number, the result is 0. Find the number.

Maurinko [17]

Answer:

The Number is 8.

Step-by-step explanation:

Let the number be x.

Given:

1/2 is subtracted from four times the reciprocal of a number, the result is 0.

Hence the equation will become like;

$4\times \frac{1}{x} - \frac{1}{2}=0$

Now Solving the equation we get.

$\frac{4}{x} -\frac{1}{2}=0\\\\\frac{4}{x} = \frac{1}{2}\\\\x= 4\times 2\\x=8$

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.

Hence the number is 8.
