<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

What is the function to 5c+4=2 (c-5)
Vinvika [58]
To solve the function we proceed as follows:
5c+4=2(c-5)
opening the parentheses we get:
5c+4=2c-10
putting like terms together we get
5c-2c=-10-4
3c=-14
c=-14/3
