Answer:
One solution
Step-by-step explanation:
Different slopes mean the lines are not parallel, so they will meet at one point
1 intercept
there are 3 possibilities: 0, 1, and unlimited intercepts
0 intercepts are with the same slope (m), 1 intercept is with different slopes (correct answer) and unlimited intercepts are when the line is the same (same m and b)
x ≤ 0.80
at least = ≤
x = each week
500x + 800 ≤ 1200
-800 -800
500x = 400
500x/500 = 400/500
x = 0.80
68b
I think it should be B because the depth of the water should be decreasing slowing at the same rate.
