Answer:
y = 3/4 x - 5
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals. We find the slope of the given line. Then we can find the slope of the reciprocal.
4x + 3y = -6
Solve for y.
3y = -4x - 6
y = -4/3 x - 2
The slope of the original line is -4/3.
The slope of the perpendicular is 3/4.
Now we need to find the equation of line with slope 3/4 that contains point (4, -2).
y = mx + b
-2 = (3/4)(4) + b
-2 = 3 + b
-5 = b
b = -5
The equation is
y = 3/4 x - 5
Answer:
If this is a proof then here is the answer.
Angle ABD is Congruent to Angle CBD = Given
Angle BDA is Congruent to Angle BDC = Given
Angle ABD is Congruent to Angle CBD = Definition of Angle Bisector
Line Segment BD is Congruent to Line Segment BD = Reflexive Property
Line Segment AB is Congruent to Linge Segment CB = Angle-Side-Angle or ASA
Step-by-step explanation:
Lucky for you, I just learned this also ;)
Since you are given your first two directions, put them down as GIVEN in the proof.
Next, Since ABD and CBD are congruent angles, you can assume that it is an angle bisector since angle bisectors always bisect equally.
Then, (This one is obvious), since Line Segment BD shares a side with itself, it is equal by the Reflexive Property (EX: AB is congruent to AB).
Finally, Since there is two angles with a congruent side in the middle, you can confirm that it is equal by Angle-Side-Angle.
Hope this helped!
The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
