Answer:
81 meters.
Step-by-step explanation:
The height (in meters), h(x) of a hovercraft x seconds after takeoff, is modeled by:

We are to determine its height at the time of takeoff.
Now, at the time of takeoff, x=0.
We substitute x=0 to solve for h.

The height of the hovercraft at takeoff is 81 meters.
The slope of 6x + 2y = 4 is
y = -3x + 2
The answer to this problem would be:
0.279 x 53 = 14.787
1. 950
2. 608
3. 1,976
4. 2,698
5. 1,216
The answer to 134.42 by 28 is estimated to 4.8
