f(19) = 3 / 19 + 2 - Sqrt 21 - 3

= 3/21 - 4

= - 81/21

= - 27/7

Answer:

f(19) = - [tex]\frac{27}{7}[/tex]

Step-by-step explanation:

Given

f(x) = [tex]\frac{3}{x+2}[/tex] - [tex]\sqrt{x-3}[/tex]

To evaluate f(19), substitute x = 19 into f(x) , that is

f(19) = [tex]\frac{3}{19+2}[/tex] - [tex]\sqrt{19-3}[/tex]

       = [tex]\frac{3}{21}[/tex] - [tex]\sqrt{16}[/tex]

       = [tex]\frac{1}{7}[/tex] - 4

       = [tex]\frac{1}{7}[/tex] - [tex]\frac{28}{7}[/tex]

       = - [tex]\frac{27}{7}[/tex]

The second of three numbers is 6 times the first. The third number is 1 more than the second. If the first is decreased by twice the third, the result is -35. What are the numbers?

Answers

Answer:

1st number:  3

2nd number:  18

3rd number:   19

Step-by-step explanation:

let 'f' = 1st number

let '6f' = 2nd number

let '6f + 1' = 3rd number

f - 2(6f + 1) = -35

f - 12f - 2 = -35

-11f - 2 = -35

-11f = -33

Under his cell phone plan, Owen pays a flat cost of $67.50 per month and $4 per gigabyte. He wants to keep his bill at $71.90 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Owen can use while staying within his budget.




Equation:



Answer:g=



Help please

Answers

Answer:

1.1 gigabytes

Step-by-step explanation:

Let us represent:

The number of gigabytes = g

Under his cell phone plan, Owen pays a flat cost of $67.50 per month and $4 per gigabyte. He wants to keep his bill at $71.90 per month.

The Equation is given as:

$71.90 = $67.50 + $4 × g

71.90 = 67.50 + 4g

71.90 - 67.50 = 4g

4.4 = 4g

x = 4.4/4

x = 1.1 gigabytes

Therefore, the number of gigabytes of data Owen can use while staying within his budget is 1.1 gigabytes
