We may answer the question above by substituting the values of the coordinates of the points in the choices to the x and y of the inequality. 
A. (-2, 4)     4 - 4(-2) ≤ -6     12 ≤ -6   FALSE
B. (1, -2)     -2 - 4(1<span>) ≤ -6      -6 ≤ -6   TRUE
C (1, 3)        3</span> - 4(1<span>) ≤ -6      -1 ≤ -6   FALSE
D. (2, 3)       3</span> - 4(2<span>) ≤ -6      -5 ≤ -6   FALSE

Answer:

x=2\\y=22\\or\\(2,22)

Step-by-step explanation:

x+y=24\\y=11x

Subtitute y in the first equation.

x+y=24\\x+11x=24\\12x=24\\x=\frac{24}{12}\\ x=2

Now replace x in either equation to find y.

y=11x\\y=11(2)\\y=22

A plane is flying from Albuquerque new Mexico to Austin Texas so far it has flown 161 miles or 23% of the total distance of the
Karo-lina-s [1.5K]

Answer: 700 miles.

Step-by-step explanation:

1. You know that 23% of the total distance of the flight from Albuquerque New Mexico to Austin Texas is 161 miles.

2. Then, keeping that information on mind, you can calculate the total distance of the flight (which you call x) as following:

\frac{161miles}{23\%}=\frac{x}{100\%}

Solve for x. Then, you obtain that the result is:

x=\frac{161miles*100\%}{23\%}\\x=700miles
