3x + 1 ≤ 1
Subtract 1 from each side: 3x ≤ 0
Divide each side by 3 : <em>x ≤ 0</em>
Answer:
C) They walked in one direction, then they were still, then they walked in the opposite direction.
Explanation:
John and Caroline go out for a walk one day. This graph represents their distance from home.c According to the graph they walked with almost same in both the direction.
First they walked in one direction and travel 30 meter in same direction then they were still for some time. Then they walked in the opposite direction for 30 meter. They walked in both the direction with approximately equal speed.
Thus, Option C is correct.
Answer:
1.96m/s^2
Explanation:
According to Newtons second law;
F = ma
a = F/m
a = nR/m
a = nmg/m
a = ng
n is he coefficient of friction = 0.2
g = 9.8m/s^2
a = 0.2 * 9.8
a = 1.96m/s^2
Hence the acceleration of the box is 1.96m/s^2
