Step-by-step explanation:
Right angle = 90°
(x + 3) + (x - 1) + (x + 1) = 90
3x + 3 = 90, x = 29.
Supplementary angles = Angles that add up to 180°.
x + (x + 104) = 180
2x = 76, x = 38.
There isn't any choices given in this problem but I can give you a tip to answer these kinds of problem. When you say independent, it means that the equation cannot be algebraically altered to result to 3x + 4y = 8. So the equation 6x + 8y = 16 is not an independent equation since when you divide each side by 2 it will result to 3x + 4y =8. You get the idea. <span />
It's a non-constant linear function, so both the domain and the range are all real numbers.
When you look at the x = 0 and y = -2, that is the y-intercept since the x = 0.
Then when you look at the second one, it goes right one and up four.
As rise over run, it would be 4 / 1 or simply 4.
The slope is 4 and the y-intercept is -2
Plug it in the equation: y = mx + b. M is the slope and B is the y-intercept.
y = 4x -2
3y = x - 1...I am going to re-arrange this.....-x + 3y = -1
-x + 3y = -1
x - 2y = 2
---------------add...u will notice that the x's cancel
y = 1
3y = x - 1
3(1) = x - 1
3 = x - 1
3 + 1 = x
4 = x
solution is (4,1)
