Move constant: 5x+3=18
subtract the numbers: 5x=18-3
divide both sides by 5: 5x=15
answer: x=3

Subtract 18 and 3 and you get 15, and then divide with 5. x equals 3

Carla is mixing cherry, grape and lime candies in a bowl. Since her favorite flavor is cherry, she wants 2/5 of the candies to b

fgiga [73]

Answer:

7/20

Step-by-step explanation:

5/5 same as 1 is the overall mixture

so 5/5 - 2/5 of the cherry = 3/5

3/5 is left and she puts 1/4 lime

3/5 - 1/4 = 7/20

7/20 is the fraction left and it goes to grape

How many fixed points are there for the function f(x) = x^5?

Rufina [12.5K]

Using the fixed point concept, it is found that f(x) has 3 real fixed points.

-------------------------------

The fixed points of a function f(x) are the values of x for which:

$f(x) = x$

In this question:

$f(x) = x^5$

Then

$x = x^5$

$x^5 - x = 0$

$x(x^4 - 1) = 0$

Applying subtraction of perfect squares, $x^4 - 1 = (x^2 - 1)(x^2 + 1)$

Again, $x^2 - 1 = (x - 1)(x + 1)$

Then

$x(x^4 - 1) = 0$

$x(x - 1)(x + 1)(x^2 + 1) = 0$

There are 3 real fixed points, $x = 0, x = 1$ and $x = -1$ .

Which statement best describes the domain of the function represented in the graph?

Vilka [71]

Given:

The graph of a function.

To find:

The correct statement for the domain of the given function graph.

Solution:

Domain is the set of x-values for which the function is defined or it is the set of input values.

From the given graph it is clear that it is a linear function with end points (1,2) and (9,14).

So, the given function is defined for $1\leq x\leq 9$ . Here 1 and 9 are including in the set of x-values.

Therefore, the correct option is C, i.e., $1\leq x\leq 9$ or x between 1 and 9, inclusive.
