Answer:
m = 1/3, b = 2
Step-by-step explanation:
The equation is already written is slope-intercept form, y = m x + b.
If h is m above the ocean and your trying to find when the rocket reaches that ocean… as the function gives the height above the ocean at a given time, when the height equals 0 the rocket will have reached the ocean so solve for t when h=0. working out in the photo. i got t=48.88seconds
The top question is B. 30, because you have to set 7y-30 equal to 4y+60 since both lengths are the same.
