Answer:
-5/-2 or 2.5
Step-by-step explanation:
Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.
Answer:
$440
Step-by-step explanation:
notes $2 - n
notes $10 - m
n + m = 80 ----------> m = 80 - n
1 - 2/5 = 3/5
45 * $2 + 35 * $10 = 90 + 350 = $440
4 what do you think it is 1000000000
51.25 per month which is $615 per year
They save 5 per month if they pay full year
(51.25-5)= 46.25 per month is $555
so it costs $555 if they pay all at once.
