I only know the part 3*n-8≤ -7
You could make a frequency chart or draw a graph.
16 - 4 + (160 / 20) 4 = 16 - 4 + 8*4
= 16 - 4 + 32
= 46
Step-by-step explanation:
From the table we can make comparison between the distance travelled and the time taken. It can be seen that the time increases as the distance decrease.
If the car travels 700 miles in 0.5seconds and 600miles in 1.5secs, we can calculate the speed of the car using the formula;
v = change in distance/change in time
v = ΔS/Δt
v = 700-600/0.5-1.5
v = 100/-1
v = -100mi/hr
Since Speed = Distance/Time
-100 = 480/Time
Time = 480/-100
Time = -4.8s
Hence it will take the car 4.8seconds to travel 480miles.
Answer:
y = -80x + 410
Step-by-step explanation:
(1,330) is the first point, the other point is (4,90)
m = y2 - y1/x2 - x1
m = 90 - 330/4 - 1
m = -240/3
m = -80/1
m = -80
y - y1 = m(x - x1)
y - 330 = -80(x - 1)
y - 330 = -80x + 80
y = -80x + 80 + 330
y = -80x + 410
