Answer:
Plane A and QRV intersection line is QR.
Explanation:
The plane QRV contains the rectangle QRVN. This rectangle intersects the plane A in the line QR.
Plane A and QRV intersection line is QR.
If one knows a specific line in one plane (for example, two points in the plane), and this line intersects the other plane, then its point of intersection.
Thus, it is on the line of intersection for the two planes.
Answer:
-439
Step-by-step explanation:
Think of the question as s(f(-7))
First replace x with -7 in the equation f(x)= 3x
s(-7) = 3*(-7)
s(-7) = -21
now it is s(-21)
we substitute -21 into the s(x) equation to get 
That gives you 2-441 = -439
Answer:
Step-by-step explanation:
m∠3 = 18°
m∠1 = 90° - 18° = 72°
m∠2 = 180° - 2(72°) = 36°
m∠4 = 2(72°) = 144°
Ok so you have $685 plus an extra $85 for the installation. You have a total of $770. You divide this by two to find per year. It is $385 per year. Now divide that by twelve for the monthly cost and you get $32.08
Answer:
$13 or $7 off
Step-by-step explanation:
20-35%=13
So that means that it is $7 off and it is now $13
