Answer:
Step-by-step explanation:
Alright, lets get started.
Lets split the given graph in three parts.
First part: 0 to 30 minutes
We can see between this period, 0 to 30 minutes, the distance from home keeps increasing. It means from 0 to 30 minutes, Eli is moving towards the library.
Second part: 30 to 120 minutes
between 30 to 120 minutes,the distance from home does not changes. It means during this period, Eli is at the library.
Third part : 120 minutes to 135 minutes
Between 120 to 135 minutes, the distance from home is decreasing.
It means Eli is returning home in that period.
It means, at 120minute, Eli started her bicycle , home from the library. Hence option (b) : Answer
Hope it will help :)
4x = -60 - 19y
-7x = -48 - 19y
Subtract the bottom equation from the top:
4x + 7x = -60 + 48 - 19y + 19y
Simplify:
11x = -12 -0y
11x = -12
Divide both sides by 11:
11x/11 = -12/11
Simplify:
x = -12/11
Then plug in x to solve for y:
4(-12/11) = -60 - 19y
Simplify:
-48/11 = -60 - 19y
Add 60 to both sides (keep in mind 60 = 660/11):
-48/11 + 660/11 = -60 + 60 - 19y
Simplify:
612/11 = 0 - 19y
612/11 = -19y
Divide both sides by -19 (keep in mind that dividing by -19 is the same as multiplying by -1/19):
612/11 • -1/19 = -19y/-19
Simplify:
-612/209 = y
y = -612/209
So, the answer is: (-12/11, -612/209)
Well, can I see the line please?
