Answer:=6x3−9c
Step-by-step explanation:
3x3+4x2+3x3−4x2−9c
=3x3+4x2+3x3+−4x2+−9c
Combine Like Terms:
=3x3+4x2+3x3+−4x2+−9c
=(3x3+3x3)+(4x2+−4x2)+(−9c)
=6x3+−9c
X/(-9) = 16
x/(-9) x (-9) = 16(-9)
x = 16(-9)
x = - 144

Answer:
its A. moderate and positive
Step-by-step explanation:
The answer is True. In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
Step-by-step explanation:
Slope of line ST = Slope of line PQ = -3.
y = -3x + c
When x = 3, y = -1
=> (-1) = -3(3) + c, c = 8
Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.
