A dune buggy is on a straight desert road, 40 km north of Dustin City. The vehicle can travel at 45 km/h off the road and 75 km/h on the road. The
driver wants to get to Gulch City. 50 km east of Dustin by another straight
road, in the shortest possible time. Determine the route he should take.

option: d is correct

step-by-step explanation:

can you make your screen more see able?

then i might be able to .

multiply then divide

step-by-step explanation:

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.
