Answer:

Step-by-step explanation:

First, since y is less than or equal to x+4, that shows that it must be either C or D, because both of those regions are below the line x+4.

Next, since y is more than or equal to -3/2x-1, this shows that C is the answer.

We can also check by seeing the graph when x = 0. Notice that y = 0 is in the region C, and notice that 0 satisfies the 2 inequalities, because -1≤0≤4.

Answer:

180 rabbits

Step-by-step explanation:

The correct question is

The rabbit population in a certain area is 500% of last years population. There are 900 rabbits this year. How many were there last year?

we know that

900 rabbits represent 500% of last year population

Last year population represent 100%

using proportion

Find out how many rabbits represent a percentage of 100%

$\frac{900}{500\%}=\frac{x}{100\%}\\\\x=900(100)/500\\\\x=180\ rabbits$

The function f(x) = 200(0.5)x/50 models the amount in pounds of a particular

victus00 [196]

Answer:

29 years

Step-by-step explanation:

Given the function $f(x)= 200(0.5)^{\frac{x}{50} }$ , where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.
Another way of doing this is to change the function to $f(x)=200(0.5^{\frac{1}{50} })^{x}$ which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate.
I'll use the 1st function because the question doesn't ask for the rate

$f(x)= 200(0.5)^\frac{140}{50}}$

From here I'll just use a calculator & get 28.7, or 29 years.
