What is true of the function g(x) = -2x² + 5?
Dafna1 [17]

Answer:

C.) The variable x represents the independent variable

Step-by-step explanation:

The variable "x" is the independent variable because that is the value that we can manipulate. We cannot manipulate the dependent variable because it is determined by the independent variable. In that case, "y" would be the dependent variable because its value is dependent on what "x" is.

A.) is incorrect because g(x) symbolizes the input of the variable "x" into the g function.

B.) is incorrect because "x" is the input.

D.) is incorrect because "x" is the input.

Suppose that a compensation professional would like to calculate the median salary. he orders four salaries as follows: $20,000,
Anastasy [175]
The median means the middle number.
First, you put them in order from least to greatest.
Then, you look to see which number is in the middle.

Since there are only four numbers given, you have to go in between two of the numbers.

The median is in between 22,000 and 24,000.

20,000  22,000  _  24,000  26,000

The number that is equally between 22,000 and 24,000 is 23,000.

The median for the set of data is $23,000.

Hope this helps!

Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2
nlexa [21]

Answer:

Yes!

The solution to the equation is n = 2

Step-by-step explanation:

Given the equation

4\left(n\right)-3=-2\left(n\right)+9

remove the parentheses

4n-3=-2n+9

Add 3 to both sides

4n-3+3=-2n+9+3

Simplify

4n=-2n+12

Add 2n to both sides

4n+2n=-2n+12+2n

Simplify

6n=12

Divide both sides by 6

\frac{6n}{6}=\frac{12}{6}

Simplify

n=2

Therefore, the value of n = 2.

Hence,

Yes!

The solution to the equation is n = 2
