In 1497, Vasco da Gama set sail from Portugal to find a sea route to India. He traveled 46.2, 48.4, and 56.2 nautical miles on
the first three days. How many nautical miles did he have to travel on the fourth day to reach an island that was 206.1 nautical
miles from his starting point?
0
A.55.3 nautical miles
B.150.8 nautical miles
O
C.58.1 nautical miles
D.49.7 nautical miles

because 1.2 isnt half of 6 duh

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
