2x+10, multiply to two each term x and 5
tan ( y ) = 10 / 8
tan ( y ) = 5 / 4
tan ( y ) = 1.25
y = 51.4 degrees ( approximately )
The correct answer would be C.439:))))))
Answer:
(-3, 8) is the solution
Step-by-step explanation:
The LCD of the first equation is (3)(4) = 12. Rewriting this equation, we get:
4x + 3y = 12
to which we add the second equation, obtaining:
4x + 3y = 12
2x - 3y = -30
-------------------
6x = -18
Dividing both sides by 6 yields x = -3
Substituting -3 for x in the first equation yields 4(-3) + 3y = 12, or
-12 + 3y = 12
Then 3y = 24 and y must be 8.
The solution to this system of linear equations is (-3, 8).
Answer:
The answer is 111°
