Find (f-g)(x). What is the domain of f/g f(x)=2x-5 g(x)=2-x

1 answer:

6 0

$f(x)=2x-5 , \ \ \ \ g(x)=2-x \\\\(f-g)(x)=f(x)-g(x) = 2x-5 -(2-x)=2x-5-2+x = 3x+5 \\\\\\
 domain : \frac{f}{g}=\frac{2x-5}{2-x}\\\\2-x\neq 0 \\ \\x\neq 2 \\ \\D=R\setminus \left \{ 2 \right \}$

Find the greatest and least number from 5,0,8,9 and 7

Dvinal [7]

Answer:

Greatest number: 98750
Least number: 5789

Explanation:

To find the greatest number with the following values, we must arrange the numbers in descending form.

=> We can clearly tell that the numbers in descending form is 9 > 8 > 7 > 5 > 0

Hence, the greatest number with the following numbers (5,0,8,9, and 7) will be 98750.

To find the least number with the following values, we must arrange the numbers in ascending form.

=> We can clearly tell that the numbers in ascending form is 0 < 5 < 7 < 8 < 9

Hence, the least number with the following numbers (5,0,8,9, and 7) will be 5789

Find the missing lengths of the sides

Ket [755]

ANSWER

The correct answer is C

EXPLANATION

The given triangle is a right triangle. Since two angles are equal, it is a right isosceles triangle.

This implies that, x=8 units.

Using Pythagoras Theorem,

${y}^{2} = {8}^{2} + {8}^{2}$

This implies that:

${y}^{2} = 64 + 64$

${y}^{2} =128$

Take positive square root,

${y} = \sqrt{128}$

${y} = 8 \sqrt{2}$

The correct answer is C
