Answer:

(-2,2)

Step-by-step explanation:

the red line is y = x + 4 ( we know this as x = -4 is the x intercept)

the green one is y = -x (it intercepts in origin)

so, we equal the two equations to each other to get the interception point:

x + 4 = - x

4 = -2x

x = -2

we substitute x = -2 in any of the equations we get

y = -2 + 4 = 2 or y = -(-2) = 2

so the point is (-2,2) which is option C.

The correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

The formula utilised to find the distance between two points is;-

X = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

We have the coordinates of the point A = (0, 0) and D is (0, b).By applying the formula to find the distance between A and D.

AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

Therefore the correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

Answer:

The answer to your question is x = 0 and x = 1

Step-by-step explanation:

Equation

$\frac{x}{x - 2} + \frac{x - 1}{x + 1} = -1$

$\frac{x(x + 1) + (x - 2)(x - 1)}{(x - 2)(x + 1)} = - 1$

Expand

2) x² + x + x² - x - 2x + 2 = -1(x - 2)(x + 1)

Simplify

3) 2x² -2x + 2 = -1(x² + x - 2x - 2)

4) 2x² - 2x + 2 = -x² + x + 2

Equal to zero

5) 2x² - 2x + 2 + x² - x - 2 = 0

6) 3x² - 3x = 0

Factor

7) 3x(x - 1) = 0

8) 3x₁ = 0 x₂ - 1 = 0

9) x₁ = 0/3 x₂ = 1

10) x₁ = 0 x₂ = 1
