Can u me show my work and answer the question

The total duration of the trip is 5 3/4 hours. Thus, you just need to calculate each segment separately.

Since you know he drove 168 miles in 3 1/2 hours, you only need to calculate how far he travelled for 2 1/4 hours.

Speed is distance per unit time.

Calculate 168 / 3.5h which will give you 48 miles per hour. That is the speed at first.

After that, the speed increases by 5miles per hour so it becomes 53 miles per hour.

calculate the distance (s × t) = 53 × 2 1/4

Add the two distances together which gives you 168 + (53 × 2 1/4) = 287.25 miles.

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.
