Answer:
- object is moving to the right with constant speed
- object is moving to the left with constant speed
- object was stationary for a while, then started moving to the right with constant speed
Step-by-step explanation:
These graphs are of position, so the slope of the graph is the change of position with time, which is velocity. When the slope is positive, the velocity is positive, meaning its direction is to the right. When the slope is negative, the velocity is negative, meaning its direction is to the left.
When the slope is zero, the object is stationary (not moving). The position remains as it was.
1. The position vs. time curve is a straight line with positive slope. The object is moving to the right with constant velocity.
__
2. The position vs. time curve is a straight line with negative slope. The object is moving to the left with constant velocity.
__
3. The position vs. time curve is flat for a while, then increasing with constant slope. The object stayed where it was for a while, then began moving to the right (to larger values of x) with constant velocity.
The total cost of transactions for Belinda is $899.
<u>Solution:</u>
Given that, Belinda used an online broker who charged a flat fee of $8.99 per transaction.
Belinda bought 100 shares of of BMN Inc, stock at \$12.85 a share,
We have to find what was the total cost of the transaction?
Now, we know that, transaction cost per transaction = $8.99
And, number of transactions = 100 shares.
Then, total cost of transaction = cost per transaction x number of transactions = 100 x 8.99 = $899
Hence, the total cost of transactions is $899
Solve for X in the 2nd equation:
x+2z = 0
Subtract 2z from both sides:
x = -2z
Replace x in the first equation with -2z
-2z +y -z = 1
Combine like terms:
-3z +y = 1
Add 3z to both sides:
y = 3z +1
Replace x and y in the 3rd equation:
2(-2z) + 2(3z+1) = 4
-4z + 6z + 2 = 4
2z +2 = 4
2z = 2
z = 1
Now replace z with 1 in the other equations for x and y:
x = -2z = -2(1) = -2
y = 3z +1 = 3(1) +1 = 3+1 = 4
So you have x = -2, y = 4 ans z = 1
The answer would be written as (-2,4,1)
The answer is
528
Hope this helps!
