The answer should be the directrix because k represents the y-value of the vertex, and for this questions the parabola is probably facing upward, so the directrix is under the vertex.
Answer:
13 True
14 Sometimes
15 Never
Step-by-step explanation:
All equilateral triangles must have 60 degree angles
Sometimes a acute triangle can have 2 acute angles
Obtuse angles take up majority of the mesuares in the triangle. All triangles must have 3 angles equal up to 180 degrees
<span>In circle F, what is the measure of ∠ CED ?
Given mAB = mBC = mCD = 36</span>°<span>
So
</span> ∠ CED = 1/2(mCD) = 1/2(36°) = 18°
Answer:
<span>B. 18</span>°<span>

Answer:
y = -2/3x + 4/3
Step-by-step explanation:
If two lines are perpendicular, the product of their slopes is -1
comparing what we have with the general form;
y = mx + b
The slope of the given equation is 3/2
To get the slope of other;
3/2 * m = -1
3m = -2
m = -2/3
So we want to write the point-slope equation
y-y1 = m(x-x1)
y-2 = -2/3(x + 1)
3y - 6 = -2x -2
3y = -2x -2 + 6
3y = -2x + 4
y = -2/3x + 4/3
No, because it <em>is not a straight line when graphed.</em>
