Answer:

f(19) = - 27/7

Step-by-step explanation:

f(x) =  \frac{3}{x + 2}  -  \sqrt{x - 3} \\ f(19) =  \frac{3}{19 + 2}   -  \sqrt{19 - 3}  \\ f(19) =  \frac{3}{21}  -  \sqrt{16}  \\ f(19) =  \frac{1}{7}  - 4 \\ f(19) =  \frac{1}{7}  -  \frac{28}{7}  \\ f(19) =  -  \frac{27}{7}

Answer:

The simplified form is x\geq -99.

Step-by-step explanation:

Given : Expression \frac{x}{3}\geq -33

To find : The simplified expression ?

Solution :

Expression \frac{x}{3}\geq -33

Multiply 3 both side,

\frac{x}{3}\times 3\geq -33\times 3

x\geq -99

Therefore, the simplified form is x\geq -99.

telo118 [61]
Alright, so since I don't have an example question, I will make one up. 

there are 8 coins in total. there are 6 dimes. What is the fraction of dimes to coins. 

you would put the amount of dimes on the top and the total on the bottom.

Answer: 6/8 which can be simplified to 3/4

Or another Example:

There are 12 pieces in the pizza. Billy took 4. what is the fraction of the slices left.

it would be 4-12= 8

Answer: 8/12 which can be simplified to 4/6 and then to 2/3

Hope that helped.
