Answer:

-1 <x < 7

(-1,7)

Step-by-step explanation:

open circle on the left means the number is greater than

-1 <x

Open circle on the right means the number is less than

x < 7

Since both statements are true. we combine them

-1 <x < 7

open circles means parentheses, closed circles mean brackets

xenn [34]

Is the prime factorization below correct

24
24+2.3.4

Answer: 100

Prime numbers are natural numbers (positive whole numbers that sometimes include 0 in certain definitions) that are greater than 1, that cannot be formed by multiplying two smaller numbers. An example of a prime number is 7, since it can only be formed by multiplying the numbers 1 and 7. Other examples include 2, 3, 5, 11, etc.

Remember that the general decay equation is:
$y=A(1-r)^{x}$
where
$y$ is the amount after a time $x$
$A$ is the initial amount
$r$ is the the decay percent in decimal form

The first ting we are going to do is find $r$ by dividing our decay rate of 25% by 100%: $r= \frac{25}{100} =0.25$ .
We also know from our problem that $y=64$ . Lets replace $y$ and $r$ in our formula:
$64=A(1-0.25)^{x}$
$64=A(0.75)^{x}$
We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that this situation represents exponential decay.

Now, to find the initial amount, we are going to solve our equation for $A$ :
$64=A(0.75)^{x}$
$A= \frac{64}{0.75 ^{x} }$
Notice that $A$ will depend on the number of ours $x$ .

How are polynomials like and unlike monomials? Provide an example of a monomial and an example of a polynomial. How does the fol

Ainat [17]

A polynomial is the sum of at least one term. For example, x^3+1 is a polynomial. A monomial is a polynomial with only one term, such as 2x^2. A binomial is a polynomial with two terms, and a trinomial is one with three terms. The example you gave is a trinomial (which is also a polynomial). Degree of a polynomial is the largest sum of variable powers in any term of the polynomial. So, for example, x^2 y has degree 3, and x^3+x^2 also has degree 3. A sixth degree polynomial would be x^6-2x+1, for example.
