Answer:

A) The functions are not inverses of each other.

Step-by-step explanation:

$f(g(x))=\sqrt{(x^2+3)-3}=\sqrt{x^2}=|x|\ne x$

The result of f(g(x)) is not always x, so the functions are not inverses of each other.

In general, a quadratic (or any even-degree polynomial) such as g(x) cannot have an inverse function because it does not pass the horizontal line test.

Mrs. Hinely grows roses. There are 6 roses on each of her 10 rose bushes. How many roses in all are on Mrs. Hinely's rose bushes

diamong [38]

In order to find the total number of roses, we can use multiplication. Since there are 6 roses on each bush, we can say that the answer is: 6+6+6+6+6+6+6+6+6+6. Since multiplication is a way to quickly add the same number, we can use 6*10. This becomes 60.

Good luck :D

Answer:

Equation: $8.5t+6.5=57.5$

Solution: $t=6$

Step-by-step explanation:

Let be "t" the number of movie tickets bought by the group of friends.

According to the information given in the exercise, the price of each movie ticket is: $8.50.

Then, you can represent the amount (in dollars) the group of friends spent in movie tickets, with this expression:

$8.5t$

You know that one person spent $6.50, then the expression that represents the total amount (in dollars) the group of friends spent in food and movie tickets, is:

$8.5t+6.5$

Since that total amount spent is given in the exercise, you can write the following equation to determine how many tickets were bought:

$8.5t+6.5=57.5$

Finally, you can solve for "t" in order to find the solution of the equation. This is:

$8.5t=57.5-6.5\\\\t=\frac{51}{8.5}\\\\t=6$
