6. Find the solution to a system of inequalities. (6 points) A. Graph this system of inequalities. Identify the solution region on the graph. (5 points: 2 points for boundary lines, 2 points for shading, 1 point for identifying the solution)

y < –x + 4
y > –x – 2

B. How many solutions do this system of inequalities have? (1 point)

When you arrive at the lake, your friend realises he hasn’t got any swimming trunks. you need to ride to a sports shop. the sports shop is 8350 metres away. how many metres is it to cycle there and back?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212

Deepak plotted these points on the number line. point a: –0.3 point b: – 3 4 point c: – 11 4 point d: –0.7 which point did he plot incorrectly?
