Since they are moving in opposite directions, this is the same as Amy staying still and Erica biking at 10 meters per second away from her.
To travel 1km = 1000m at 10 meters per second, you need 1000/10 = 100 seconds.

Answer:
y = 5/3x -5
Step-by-step explanation:
The slope is the ratio of "rise" to "run" for the line. Here, marked points are 5 units apart vertically and 3 units apart horizontally. The slope is ...
m = rise/run = +5/3 = 5/3
There is a marked point on the y-axis at y = -5. That is the y-intercept. Then your equation is ...
y = mx + b . . . . . line with slope m and y-intercept b
y = 5/3x -5 . . . . . line with slope 5/3 and y-intercept -5
Answer:
36/35ab
Step-by-step explanation:
8/14*a*9/5b
rewrite
8/14a*9/5b
reduce the fraction.
4/7a*9/5b
calculate.
Which equals 36/35 ab.
Hope that helped.
1. Split the second term in 8y^2 + 17y + 2 into two terms
8y^2 + 16y + y + 2
2. Factor out common terms in the first two terms, then in the last two terms
8y(y + 2) + (y + 2)
3. Factor out the common term y + 2
(y + 2)(8y + 1)
