Answer:

{(3,9) , (7,4) , (1,6)} represents a function.

Step-by-step explanation:

A function must have only one x-value per y-value. There cannot be two or more x-values in a function with different y-values. All of the other options have two or more x-values that are the same.

-9x - x - 7x² - 6x² + 8 +6<br><br><br><br> Help please

hammer [34]

Answer:

$\boxed{ \bold{ \huge{ { \sf{ - 13 {x}^{2} - 10x + 14}}}}}$

Step-by-step explanation:

$\sf{ - 9x - x - 7 {x}^{2} - 6 {x}^{2} + 8 + 6}$

Collect like terms

⇒ $\sf{ - 7 {x}^{2} - 6 {x}^{2} - 9x - x + 8 + 6}$

⇒ $\sf{ - 13 {x}^{2} - 10x + 8 + 6}$

Add the numbers

⇒ $\sf{ - 13 {x}^{2} - 10x + 14}$

Hope I helped!

Best regards!!

When a number is added to 1/5 of itself, the result is 24. The equation that models this problem is n +1/5 n = 24. What is the v

Lady_Fox [76]

For this case we must find the value of n of the following equation:

$n + \frac {1} {5} n = 24$

Taking common factor "n" from the left side of the equation we have:

$n (1+ \frac {1} {5}) = 24\\n \frac {6} {5} = 24$

Multiplying by 5 on both sides of the equation:

$6n = 120$

Dividing between 6 on both sides of the equation:

$n = 20$

Thus, the value of n is 20.

Answer:

$n = 20$
