This one is your answer hope this helps
Answer:
h(u)=-7/6u
Step-by-step explanation:
To write a formula for v in terms of u, you need to first isolate v.
4u+8v=-3u+2v
Add 3u to both sides:
7u+8v=2v
Subtract 8v from both sides:
7u=-6v
Divide both sides by -6:
v=-7/6u

Y = 4/-3 - 1
The slope can either be -4/3 or 4/-3 and the y-intercept is (0,1)
For solving this we need the change in distance and the change in time. You said that the change in time is 1.8 seconds and the change in distance is 3.6 meters. ( This is assuming it started at 0 meters and started at 0 seconds )
Since the starting was 0,0 we can toss them out as they add no value. Now since speed is labeled (in this case) m/s, we divide how many meters it traveled over how many seconds it took to travel it.
3.6 / 1.8 = 2
The average speed of the cart is 2 m/s
Answer:
1. y = 5x + 20
2. $20 the amount you saved mowing your aunt's lawn.
3. 21 weeks
Step-by-step explanation:
1. 5 is the slope because it is the rate. 20 is the y-intercept because that is how much you already have.
2. 20 because that is how much you already have.
3. Since you already have $20, you need to subtract 125 by 20 to get 105. Then you divide 105 by 5 to get 21 weeks.
