Answer:
The displacement is: - 80 i
Step-by-step explanation:
In order to answer the question, you have to apply the displacement formula, which is:
ΔX= Xf-Xi
Where ΔX is the displacement, Xf is the final position and Xi is the initial position. The formula represents the change in the position of an object from the origin.
Let the origin be in 0 km,with the x-axis positive to te right.
Notice that the displacement is a vector. The positions are:
Xf=163 km (i)
Xi= 243 km (i)
Because John starts in 243 km and finishes in 163 km.
Where i is the unit vector in the x direction.
Therefore:
ΔX= 163 i - 243 i
Solving:
ΔX= -80 i
Notice that for calculating the displacement you just need the initial and final position. It doesn't depend on the distance traveled.
Answer:

Step-by-step explanation:
Answer:
See possible solutions below.
Step-by-step explanation:
There are no listed statements. However, looking at the function can provide important information:
- y = -4 is a horizontal line through -4 on the y-axis
- All inputs have the same output -4 in this function
- This function has a y-intercept at (0,-4)
- This function has a slope of 0
False items about this function include:
- Vertical line
- All inputs are -4
- Has on slope or slope is undefined.
Answer: 2x + 14y + 15
Step-by-step explanation:
8x - 6x + 10y + 6 + 4y + 9
Bring like terms together
8x - 6x + 10y + 4y + 6 + 9
Combine like terms
2x + 14y + 15
