1. Is the 1st problem y-x or y+x?
2, 2 not equal to 4 when subtracting
4,10 not equal to 4
6,15 not equal to 4
2. x, y. y-x=0
2, 5 x=2/5y 2=(2/5×5/1) 2=2
2-2=0
looking at the 3rd equation
the value of
x=2/5y. 5/2x=y or 2.5x=y
you need to divide the 2/5 to both sides. 2/5 becomes 5/2 or 2.5x.

Answer:
Option A. -(
)
Step-by-step explanation:
Equation of a given line is a + 4b = 0 or b = -
This in the form of y = mx + b, which is slope-intercept form.
Here slope of the line is (
).
Or tanθ = 
This line coincides with the terminal side of the angle in standard position where cosθ > 0
Since tanθ = 
and sinθ = 
Hypotenuse = 
= 
= 
Since tanθ is negative and cosθ > 0 that means θ lie in fourth quadrant.
Therefore, sinθ will be negative.
[
]
sinθ = -
= -
Answer will be option A.
4:15 to 5:00 is 45 minutes; 5:00 to 5:50 is 50 minutes. 50+45=95 minutes = 1 hour and 35 minutes.
