Use the inscribed angle theorem. In this case, it says that angle ACB must be a right angle, because it's an inscribed angle that subtends half the circle.

So you have

(2<em>x</em> + 5)° = 90°

2<em>x</em> + 5 = 90

2<em>x</em> = 85

<em>x</em> = 42.5

Explain what the vertical line test is and how it is used

Vertical Line Test. A test use to determine if a relation is a function. A relation is a function if there are no vertical lines that intersect the graph at more than one point.

1. What is the slope of a line that is parallel to the line represented by the equation y=-2/5x + 4/5

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the slope of the line that is parallel to the line $\star~\mathrm{y=-\cfrac{2}{5}x+\cfrac{4}{5}}$ .

$\triangle~\fbox{\bf{KEY:}}$

Parallel lines have the same slope.

So let's first determine the slope of the first line, and then let's find the slope of the line that's parallel to it.

$\circ\!\!\!\star\mathcal{HINT:}$

The slope is the coefficient of x.

So the slope is

$\star~\mathrm{-\cfrac{2}{5}}$ .

Can you guess the slope of the line that is parallel to the first line?

That's right! The slope is...

$\star~\mathrm{-\cfrac{2}{5}}$

Hope it helps you out! :D
