How bad is the heavy traffic? You can walk 15 miles in the same time that it takes to travel 30
miles by car. If the car's rate is 2 miles per
hour faster than your walking rate, find the
average rate of each.

Average rate of car: x+3

Walking rate: x

The equation is  

10/15 = x/x+3

So

x = 6

So

Average rate of car: 9 mph

Walking rate: 6 mph

Step-by-step explanation:

Average rate of car: 9 mph  

Walking rate: 6 mph

Step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
