F(x)=3 over x+2-x-3 squared what is f(7)

dimaraw [331]

<u>Answer:</u>

$f(7)=\frac{-5}{3}$ or $f(7)=-1.67$

<u>Step-by-step explanation:</u>

We are given the following function of x and we are to find the value of $f ( 7 )$ :

$f ( x ) = \frac { 3 } { x + 2 } - \sqrt { x - 3 }$

Substituting the given value (7) in the above function to get:

$f(x)=\frac{3}{x+2}-\sqrt{x-3}$

$f ( 7 )= \ frac{3}{7+2}-\sqrt{7-3}$

$f(7) = \frac { 3 } { 9 } - \sqrt { 4 }$

$f(7)=\frac{1}{3}-2$

$f(7)=\frac{1}{3}-\frac{6}{3}$

$f(7)=\frac{-5}{3}$ or $f(7)=-1.67$

Lindsey earn $70 for working 5 hours. how much does she earn for working 12 lawns?

agasfer [191]

$70 for 5 hours = 70/5 for 1 hour.

70 / 5 = 14

That means $14 for 1 hour.

To find how much for 12 hours, multiply the price of 1 by 12 to get the price of 12 hours.

1 hour = $14
12 hours = 14 * 12

14 * 12 = 168.

That means the price of working for 12 hours is $168.

Hope this helped☺☺
