Anybody got the Chapter 9 practice test answers?! I am really needing help . The first two problems are below. I need all the work and on the first and second one how i put x2 i mean that like the number of squares for x . it need a domain and range 1) Y=x2+2x+5

2) Y=2x2-3x+1

(note i put the graph in so plz )the graph shows the amount of water that remains in a barrel after it begins to leak. the variable x represents the number of days that have passed since the barrel was filled, and y represents the number of gallons of water that remain in the barrel. what is the slope of the line

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.

1.two more than the quotient of a number and 6 is equal to 7 use the c for the unknown number translate the sentence into an equation
