#3.
in this case, all you need to do is to look at the intersecting point. each units represent 2, the coordinates of the intersection are (4,-1), so D is the choice.
#4. B is the choice. two lines either intersect once (one solution), never (parallel, no solution), or overwrap (merge, infinite solutions)
N=12
1/4n = 10-7
1/4n = 3
N = 3x4 = 12
Hello there!
the solutions to this system of inequalities are every point in the blue area. In order to figure out if each of those choices are solutions, just graph the points, and if they are in the blue, they are solutions.
Using this method, you get A and C as your answers because they are in the blue region.
I really hope this helps!
Best wishes :)
Part A) you sub .3 B is answer
Part b) 23.4-.3=23.1 and 23.1-.3 is 22.8 B is answer
Your welcome!
