When you graph those points you can see that the slope of the line is 2.5. Since it is consistent it is very much a linear equation. This line also goes through the point (0, 0), which makes sense if you think about it...if you don't buy any cd's (0 cd's) you shouldnt be spending any money, right? The equation then for this relationship, using the fact that the y-intercept is 0, isy = 5/2 x or y = 2.5x. Either one is fine. They're exactly the same.
4x+3(-3x-1)=2. This is gonna lead to x=-1 and y=2
Answer:
B, She stopped to change a flat tire
Step-by-step explanation:
from minute 3 - 5, Anita was at a standstill. she did not speed up and pass Susana, as she wasnt moving
she didnt go up a hill because that requires moving
she did not win the race because there is more to the graph
The answer is x=3.6 or 3 3/5.
First we convert the decimal answer to a fraction; 0.9 is read as "nine tenths," so the corresponding fraction is 9/10:
1 5/6 - (x - 7/12) + 2 1/12 = 9/10
Now we find a common denominator. The first thing that 6, 12 and 10 will all divide into is 60:
1 50/60 - (x - 35/60) + 2 5/60 = 54/60
Distributing the negative, we have:
1 50/60 - x + 35/60 + 2 5/60 = 54/60
Combining like terms, we have:
-x + 4 30/60 = 54/60
Subtracting 4 30/60 from each side, we have:
-x + 4 30/60 - 4 30/60 = 54/60 - 4 30/60
-x = -3 36/60
Divide both sides by -1:
-x/-1 = (-3 36/60)/-1
x = 3 36/60 = 3 3/5 = 3.6
True. Distance formula will give you the length between any two points.
