For wool u bought 3 and for cotton i am pretty sure 3 and 1 left over
Remembering that "slope" signifies "rise" over "run," read off the rise and run from the illustration. If we start at x=-4 and move to the right 4 units, x becomes 0. The "run" is thus 4. At the same time, y increases from 0 to 2, and so the "rise" is 2.
The slope is rise/run = 2/4 = 1/2.
The y-intercept can also be read off the graph: Find the y-value on the x-axis where the graph (the sloping line) crosses the y-axis. It's 2.
Thus, the equation of this line is y = mx + b, or y = (1/2)x + 2.
1.
The range are y's. The y's in {(4,-1),(-7,2),(1,2),(2,1)} are -1,1,2 ⇒ A,B,C
2.
The domain are x's. The x's in {(4,-1),(-7,2),(1,2),(2,1)} are -7,1,2,4 ⇒ A,B,D
Answer:
-32 m/s
Step-by-step explanation:
Lebron bikes 800 m to the left in 25 seconds.
We are using a coordinate system where rightward is positive.
This means he is moving in the negative axis.
Hence, his displacement is actually -800m.
Velocity is the displacement moved by an object divided by the time spent i.e.
v = d / t
His velocity is therefore:
v = -800 / 25 = -32 m/s
His velocity is -32 m/s.
