Question

Please answer these as well!!! trying to pass I have 1 day !!!

Answer 1

Y = 40x + 55

not sure bout the last one tho.. sorry :(

Answer 2

Question 11:
 For this case we have a linear equation of the form:
 y = mx + b
 Where,
 m: rate of change
 x: number of hours
 b: fee charge
 In this case we have:
 b = 55 $
 m = $ 40 / hour
 Substituting the values we have:
 y = 40x + 55
 Answer:
 y = 40x + 55
 option 2

 Question 12:
 For this case, what we should do is use the following equation:
 h = v * t + h0
 Where,
 v: speed
 t: time
 h0: initial height
 h: final height
 Substituting values we have:
 102 = 4.2 * t + 27
 Clearing the time we have:
 t = (102-27) / (4.2)
 t = 17.86 seconds
 Answer:
 t = 17.86 seconds
