Answer: 40%
Step-by-step explanation: Percent change=difference/original times 100.
2/5 times 100 is 40%
-2/9 x 4/9 is -8
so the answer is -2/9
Answer:
Not parallel.
Step-by-step explanation:
If the slopes are the same they are parallel.
So we convert each one to slope-intercept form:
-5x - 4y = -3
-4y = 5x - 3 Divide both sides by -4:
y = -5/4 x + 3/4.
Slope = -5/4.
-5x – 5y = -3
-5y = 5x - 3 Divide both sides by -5:
y = -1 x + 3/5.
Slope = -1.
The slope are different - so NOT parallel.
SinФ=-12/13
cosФ=Base/hypotenus
(hy)^2-(perpendicular)^2=(base)^2=13^2-12^2=5
cosФ=-5/13
