What is the value of the y coordinate of the solution to the systems of equations x+2y=9 and x-y=3
marusya05 [52]

Answer:

y = 2

Step-by-step explanation:

(1) x  + 2y = 9

(2) x  -   y = 3

Subtract (2) from (1)

3y = 6

 y = 2

The y-coordinate is y = 2.

The graphs of the two equations intersect at (5, 2).

A tree is growing on a hill. In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a poi
melisa1 [442]
For this case what we must do is use the law of cosines.
 We have then:
 12 ^ 2 = 6 ^ 2 + 10 ^ 2 - 2 * (6) * (10) cos (x)
 Clearing we have:
 cos (x) = (12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10))
 x = acos ((12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10)))
 x = 93.82 degrees
 Answer:
 
The tree is growing in relation to the hill at:
 
x = 93.82 degrees
