First find the slope using the slope formula M= (y2-y1) divided by (x2-x1) and then take the slope and and the 1st set of points (x1, y1) and plug it into the slope intercept formula which is y-y1=m(x-x1), then you need to add or subtract variables to correlate with the standard form formula which is ax + by = c.
Hope that helps!
Answer:
Marked Price =MP=550 Marked Price =MP=550
Selling Price=SP=550-10%=550-55=495Selling Price=SP=550-10%=550-55=495
The profit earned is , SP−Profit=CP(CostPrice)The profit earned is , SP−Profit=CP(CostPrice)
CP=495−75=420CP=495−75=420
The difference of MP and CP is 550−420=130The difference of MP and CP is 550−420=130
The percentage of difference w.r.t CP is The percentage of difference w.r.t CP is
130420×100=30.95%

Answer:
A
Step-by-step explanation:
The function is 
To find the maximum population, we need to set t towards infinity to get our answer.
So, we replace time with maximum (
). Let's check:
The population of birds approaches 1620 as t goes towards infinity. So we can say the max population of the species is 1620.
Correct answer is A
Percent means per 100
think cent as in 100 pennies in a dollar
To convert from percent to decimal, we divide by 100 or move the decimal over 2 spots, so,
15% = 15/100 = 0.15
Now multiply 0.15 by 850 to find the discount saved
0.15*850 = 127.50
So you'll save $127.50
The final price is therefore: 850-127.50 = 722.50
A shortcut is to multiply 850 by 0.85
850*0.85 = 722.50
We get the same answer
The 0.85 comes from the fact that if you get 15% off, then you pay 85% of the original price
Answer: $722.50
