Answer:
x = 47/7 or 6.714
Step-by-step explanation:
7 (x+3) = 72-4
7x + 21 = 68
7x = 68 - 21
7x = 47
x = 47/7 or 6.714
Answer:
n(m%)
Step-by-step explanation:
400 miles:
593 + .33(400)= $725
800 miles:
593 + .33(800)= $857
1,200 miles:
593 + .33(1,200)= $989
For the acceleration to be uniform(gradient of equation constant), the car must have an existing velocity at time t = 0.
The acceleration (or gradient) = (54 - 50)/4
= 1 km/h
velocity = acceleration x time + initial velocity
50 = 1 x 2 + Vi
Vi = 48 km/h
The equation:
V(t) = t + 48
Where V(t) is the velocity at time t and t is the time.
The equation may be graphed by keeping time on the x axis and velocity on the y axis and starting the graph at the point (0 , 48)
