Answer:

x = 20 / √3 = 20√3 / 3

Step-by-step explanation:

AC² = AD² + BC² = x² + x² = 2 x²

AF² = AC² + CF² = 2 x² + x² = 3 x²

3 x² = 20² = 400

x² = 400/3

x = 20 / √3 = 20√3 / 3

30 POINTS!! Write the slope-intercept form of the equation for the line.
Anton [14]

Answer:

B. y = -\frac{3}{10}x + \frac{1}{2}

Step-by-step explanation:

Well slope-intercept form is y = ax + b.

Let's start with the slope.

In this case, finding the slope is easy.

It should have a negative slope.

So we can cross out answer choices A. and C.

Also, we can cross out D. because it just makes no sense, -10/3, if you start from the y-intercept and go down 10 and across 3, yeah that's

not the slope.

So we can cross out D.

The only answer choice left is B.

We can tell the y-intercept is 1/2 because like come on so B is the correct answer.

B. y = -\frac{3}{10}x + \frac{1}{2}
