<SVT=90
<QVT or QT=180
<QVR and <UVT are 49 degrees so <SVR is 41 because 41+49 is 90
3x+4= 3(15)+4 = 45+4 = 49 so it's right
(2x -5y) + (x+y) =
2x - 5y +x + y =
3x -4y
Answer:
Step-by-step explanation:
The standard equation for a parabola is
with vertex at (h, k) and a focal length of |p|
:
or
Comparing this with the standard form we get
The parabola is symmetric around the x-axis.
The focus lies a distance from the center along the x axis
So focus is at
The parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis at a distance -p from the center
