an airplane begins to descend for a landing. the elevation g (in feet) of the airplane is modeled by the function: g(t)= 4800-300t, where t is the time (in minutes) since the airplane began to descend. what is the y- intercept?

The y-intercept in this case is 4800

Step-by-step explanation:

The equation of a line graph is ;

y = mx + c

with respect to the given equation in the question, the y-intercept in this case is 4,800

In this case the y-intercept represent the height from which the plane starts to descend

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
