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).
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
6 1/2 - 3 2/3 =
13/2 - 11/3 =
39/6 - 22/6 = 17/6 = 2 5/6 qts left
-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
Answer:
2/3 to the power 8
Step-by-step explanation:
Power : 2 + 6 = 8
