<span>X/9=-5
First: To get your x alone, and to get rid of your fraction you would multiply each side by 9.
You would get: x=-45 <That would be your answer
HOPE THIS HELPS! ^_^</span>
The linear function that can be used to determine the height, H, of the plane after m minutes is given by:
H(m) = 8000 - 500m
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.
In this problem:
- The plane is descending from an altitude of 8,000 feet, hence the y-intercept is b = 8000.
- The plane descends at a constant rate of 500 feet per minute, hence the slope is of m = -500.
Thus, the equation is:
H(m) = 8000 - 500m.
