100 points! Will give brainliest! Which of the following systems of inequalities has point D as a solution?

f(x) ≤ 3x + 4

g of x is less than or equal to negative one half times x minus 5

f(x) ≥ 3x + 4

g of x is less than or equal to negative one half times x minus 5

f(x) ≤ 3x + 4

g of x is greater than or equal to negative one half times x minus 5

f(x) ≥ 3x + 4

g of x is greater than or equal to negative one half times x minus 5

B) f(x) ≥ 3x + 4

g of x is less than or equal to negative one half times x minus 5

Step-by-step explanation:

From the above graph,  

If point B is the solution of the system of inequalities, then point B must satisfies both inequalities  

We can see from the graph that

Point B is located above (≥) the boundary line for f(x) and is also below (≤) the boundary line for g(x).

So we can say,

Point b satisfies the inequalities

Therefore,  

The system is  

 f(x) ≥ (3x+4)

 g(x) ≤ (-1/2x -5)

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

x = 23.78
