3x < -6
x < -6/3
x < -2
Therefore, the solution set is {x | x < -2}.
Answer:
2y^2 +18x
Step-by-step explanation:
4y^2+6x-2y^2+12x
Combine like terms
4y^2-2y^2 +6x+12x
2y^2 +18x
A(x1, y1), B (x2,y2)
d=V(y2-y1)^2+(x2-x1)^2
d^2= (1-4)^2+[5-(-2)]^2=(-3)^2+ (5+2)^2=9+49=58
d=V58
a straight horizontal line on a speed-time graph means that speed is constant.
