Step-by-step explanation:
60°= one half
Answer:
(-1/2,-5/2)
Step-by-step explanation:
x-y = 2
x+y = -3
---------------
Through Elimination, we can just add the system of equations. The y cancels out and gives us the single equation for x:
2x = -1
x = -1/2
Substitute -1/2 for x in either equation and you get:
(-1/2) + y = -3 Solve for y
y = -5/2

Step-by-step explanation:
everything can be found in the picture
You can rewrite the second equation because you know what y equals, so you can write it as 2x + x + 3 = 9
3x + 3 = 9
- 3
3x = 6
÷ 3
x = 2
And now you use the equation of what y equals and substitute in the value of x, so y = 2 + 3
y = 5
So your final answer is A. (2, 5). I hope this helps!
Answer:
y = - x - 6
Step-by-step explanation:
y = mx + b
m = - 1
y = - x + b
(- 4, - 2)
- 2 = - (-4) + b
-2 = 4 + b
b = - 6
y = - x - 6
