Answer:
The solution is (3, -3)
Step-by-step explanation:
5x + 2y = 9
2x - 3y = 15
Use elimination by addition/subtraction. Multiply the first equation by 3 and the second by 2, obtaining:
15x + 6y = 27
4x - 6y = 30
----------------------
19x = 57
This yields x = 3.
Substituting 3 for x into 5x + 2y = 9, we get 5(3) + 2y = 9, or
15 + 2y = 9, or
2y = -6
This yields y = -3.
The solution is (3, -3)
18.25 inches long.
129.25 - 18.5 - 18.5 - 18.5 - 18.5 - 18.5 - 18.5 = 18.25 inches
The tangent of 75 maybe? Depending on calculator tangent button then 75 or vice versa
