0.4n-3(n+0.1)
0.4n-3n-0.3
-2.6n-0.3
Answer:
Step-by-step explanation:
(-5,5)...x1 = -5 and y1 = 5
(5,-4)...x2 = 5 and y2 = -4
slope = (y2 - y1) / (x2 - x1)
slope = (-4 - 5) / (5 - (-5) = -9 / (5 + 5) = -9/10 <==
X=2 y=4 substitute y=2x into x=-y+6 so it’s x=-2x+6 add the 2x on both sides 3x=6 divide by 3 x=2 and plug that into y=2x so it’s just 2x2 which is 4
Answer:
Step-by-step explanation:
Put the side length where x is, then do the arithmetic.
P = 4x
P = 4(5/7) = 20/7
The perimeter is 20/7 units.
