Explanation:
Remember that in the exponential growth and decay form r is the rate of growth or decay. Thus, notice that according to the problem, the population grows at 3% per year.
Then, we can conclude that the correct answer is:
Answer:
0.03
Answer:
y = 1/4x - 1.75
Step-by-step explanation:
standard form is y = mx + b
to get m you need to calculate the slope between the given points
m= (y1-y2)/(x1-x2)
m = (-1 - (-3))/(3 - (-5)) = 2/8 = 1/4
now you need to find the constant b by plugging in one of your points
y = 1/4x + b
-1 = 1/4(3) + b
b = -1 - (3/4)
b = -7/4 or -1.75
Answer: 9 toys have to be sold
Step-by-step explanation:
Hello there!
To solve this, we must first combine 5m and 4m
5m + 4m = 9m
So, now we have:
9m = 72
Now, we must isolate the left side, making it equal m
To do this, we will divide both sides by 9.
9m 72
---- = ----
9 9
So, now we have:
m = 8
This means that the answer is 8.
I hope helped!
