Whitney starts the engine on her small private airplane. the engine drives a propeller with a radius of 6.5 feet and its centerline 10.5 feet above the ground. at idle, the propeller rotates at a constant speed of approximately 850 revolutions per minute. the height of one propeller tip as a function of time is given by h = 10.5 + 6.5 sin(850t), where h is the height in feet and t is the time in minutes. find h when t = 2 minutes a. 4.1 ft b. 9.4 ft c. 16.9 ft d. 11.6 ft

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
