Positive acceleration indicates an increasing velocity while negative acceleration (deceleration) indicates slowing down.

X + y = 270
x - y = 26
Add the two equations: 2x = 296
x = 148
Substitute this value of x back into either of the original equations and solve for y:
148 + y = 270
y = 122
An ordered pair might be (148, 122)

To figure this out use a common denominator for the fractions:
1/6 = 4/24
1/8 = 3/24
Therefore, 1/6 > 1/8

^{2}+ 4x - 12 = 0 (x + 6)(x - 2) = 0 x - 2 = 0 x + 6 = 0 x = 2 x = -6
