Answer:
x=20
Step-by-step explanation:
10x-60=140
10x=140+60
10x=200
x=20
Answer:
y = 4 
Step-by-step explanation:
For an exponential function in standard form
y = a 
To find the values of a and b, use ordered pairs from the table
Using (0, 4 ), then
4 = a
( = 1 ), so
a = 4
y = 4
Using (1, 8 ), then
8 = 4
= 4b ( divide both sides by 4 )
2 = b
Thus
y = 4 ← exponential function
Speed is computed by dividing total distance by total time.
Speed = Total Distance / total time
From the above formula, we can derive the formula of time and distance.
Time = Distance / Speed
Distance = Speed x time
