Juan is working two summer jobs, making $8 per hour
walking dogs and making $10 per hour landscaping. In a
given week, he can work a maximum of 17 total hours and
must earn a minimum of $150. If x represents the number of
hours walking dogs and y represents the number of hours
landscaping, write and solve a system of inequalities
graphically and determine one possible solution.

One-third of the people from country a claim that they are from country b, and the rest admit they are from country a. one-fourth of the people from country claim that they are from country a, and the rest admit they are from country b. in a combined census of the two countries, one-half of the total claimed to be from a. what is the ratio of the populations of country a to that of country b.

The chs baseball team was on the field and the batter popped the ball up. the equation b(t)=80t-16•16+3.5 represents the height of the ball above the ground in feet as a function of time in seconds. how long will the catcher have to get in position to catch the ball before it hits the ground? round to the nearest second

Solve the inequaliy: (x^2+2)(x−2)^2(6−2x)> 0
