Answer:
12 miles
Step-by-step explanation:
3 miles per 30 minutes
2 hours is made of 4 30 minutes, so 3 x 4 = 12
y= 1/2x +2
if x=0 y=2 (0,2)
if x=2 y = 1/2 *2 +2 =1+2 =3 (2,3)
you now have two points so you can plot the line
Since the 37 is negative the parabola will open downward.
The coefficient on the outside of the ^2 tells you if it opens up or down. If it's positive it opens upward and if it's negative it opens downward.
For the parabola to open sideways it would be a form of x = y^2
For this case we must find the solution set of the given inequalities:
Inequality 1:

Applying distributive property on the left side of inequality:

Subtracting 3 from both sides of the inequality:

Dividing by 6 on both sides of the inequality:

Thus, the solution is given by all the values of "x" greater than 3.
Inequality 2:

Subtracting 3x from both sides of the inequality:

Subtracting 3 from both sides of the inequality:

Thus, the solution is given by all values of x less than 4.
The solution set is given by the union of the two solutions, that is, all real numbers.
Answer:
All real numbers
