Answer:
the bottom one my dude. hope it helps!
Answer:
Step-by-step explanation:
we know that
The equation of a circle into center radius form is equal to
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
substitute
I found a similar problem to your problem here, which is shown in the attached picture. So, from the picture, we have to find the equation for the red line. All we have to do is find two points of the line. That would be: Point 1(2,0) and Point 2(-2,3). The general equation would be:
y - y₁ = (y₂-y₁)/(x₂ - x₁) * (x - x₁)
Substituting the coordinates to the equation,
y - 0 = (3-0)/(-2 - 2) * (x - 2)
y = -3(x -2)/4
Rearranging,
<em>4y = -3x + 6 or 4y + 3x = 6</em>
Since D is the midpoint of CE, knowing that CD = 3x implies that DE = 3x as well.
So far, we know that:
Now, since AE and BD are parallel, the two triangles ACE and BCD are similar, which means that their corresponding sides are in the same proportion.
For this reason, we can write the following proportion:
and plug the values we wrote above:
Since the two factors in the right hand side are the same, the two factors on the left hand side must be equal as well, so we deduce which solves to .
Knowing that and that , we can easily conclude that .
Answer:
-9
Its in the format y=mx+b, where m is the slope and b is the intercept. Also since x is 0 at the y intercept, you could substitute 0 for x and see the intercept
