the final temperature was -2 F, and that reflects a drop of 13 units, so
-2------0------------------------------------------------------+11.
Answer:
AnSum of two sides of triangle always greater than third side, so the possible values of h is:
7x-3x < h < 7x+3x
4x < h < 10x answer:
Step-by-step explanation:
Plain Z<span> is the </span>plane<span> that is width basicly if looking at a 3d figure.</span>
Remember that to find the vertical asymptotes of rational functions, we just need to set the denominator equal to zero and solve for the variable, in this case
![x](https://tex.z-dn.net/?f=x)
, so lets do it:
![(x-4)(x+1)=0](https://tex.z-dn.net/?f=%28x-4%29%28x%2B1%29%3D0)
![x=4,x=-1](https://tex.z-dn.net/?f=x%3D4%2Cx%3D-1)
As you can see, our rational functions has
2 vertical asymptotes: ![x=4](https://tex.z-dn.net/?f=x%3D4)
and
IF:
|1/2.x -2/3.y = 7 and
|a.x - 8.y = -1
have no solution, that means these 2 linear equations ARE PARALLEL (since they can never meet). Reminder: 2 equations are parallel if they have the same coefficient , so let write each of the equation in the normal form:
a)1/2.x -2/3.y = 7→ -2/3.y = -1/2.x + 7 → y = 3/4.x - 21/2
b) a.x - 8.y = -1 → - 8.y = -a.x - 1 → y= a/8.x + 1
a) and b) are // if (3/4) = (a/8), [the 2 coefficient OR the 2 slopes)
a/8 = 3/4 → a = 24/4 and a = 6 (Answer D)
