A) We can pick any two values from the table then can subtract initial value from final value divide by the number of instance which will give us the rate of change.
b) Same with the graph, we take two coordinates and then apply in the formula:
slope (m) = y2-y1 / x2-x1
c) We can write the equation, by substituting into the formula:
y - y1 = m (x - x1)
Where y-interecpt & slope is most important
d) When, we completely solve the equation, then it gives y-intercept, and first value of the path in the graph is known as initial value
e) In linear interval, difference between any two instances must be same, 'cause they follow the rule of proportionality whereas in non-interval, differnce will be different in magnitude
Hope this helps!
Answer:
4 hours
Step-by-step explanation:
Hour1-
Bicycle = 24.50
ElectricScooter = 32
Hour2-
Bicycle = 34
ElectricScooter = 39
Hour3-
Bicycle = 43.5
ElectricScooter = 46
Hour4 -
Bicycle = 53
ElectricScooter = 53
Is this question lacking information? Because we don't know how much one pound costs.
Not sure if it's right but I tried:
(16,-12) assuming x=16,y=-12
y=5x-4
-12=5(16)-4
-12=240-4
-12=236
(Divide maybe?)
-12=236
236 divided 12= 19.6
The rule says that:
each small angle has a small side
then the angle in front of BC is the smallest
in front of CA is the middle
in front of AB is the largest
I hope this helped and Good luck
thank you
