Answer:
f = e/2
Step-by-step explanation:
e = 2f
Switch sides.
2f = e
Divide both sides by 2.
f = e/2
The answer is -1.
First, distribute the negative inside the parenthesis of 1/2.
Next, turn all the denominators into 6 by multiplying by 3 or 2.
-1/2 + 2/3 + -1 1/6
Changes to -3/6 + 4/6 - 1 1/6
-3/6 + 4/6 = 1/6
1/6 - 1 1/6 = -1
Answer:
Step-by-step explanation:
Assuming, we the given polynomial is
and the divisor is
Then , the polynomial division is shown in the attachment.
This implies that:
Answer: y = (-1/2)x + 1 which is the same as y = -0.5x + 1
We'll use y = mx+b with m as the slope and b as the y intercept
The slope is m = -1/2 = -0.5 because we go down 1 each time we move to the right 2 units. We have rise = -1, run = 2, so slope = rise/run = -1/2 = -0.5.
The y intercept is where the line crosses the y axis, so b = 1
Use m = -1/2 and b = 1 to go from y = mx+b to y = (-1/2)x+1
assuming north as positive direction and south as negative direction of motion
y = path travelled in north direction = 20 kilometer
y' = path travelled in south direction = - 15 kilometer
distance travelled is given as
distance = d = |y| + |y'| = 20 + 15 = 35 kilometer
displacement is given as
displacement = D = y + y' = 20 + (-15) = 5 kilometer
Ratio of distance travelled to displacement is given as
Ratio = d/D = 35/5 = 7
Ratio = 7:1
