Answer:
x - 4
Step-by-step explanation:
The expression simplifies to ...
[tex]\sqrt{x^2-8x+16}=\sqrt{(x-4)^2}=|x-4|[/tex]
For x ≥ 4, the argument of the absolute value function is non-negative, so it remains unchanged. The simplified expression is ...
x - 4 . . . . for x ≥ 4

1\tfrac{2}{5} \div \frac{8}{9}
1 5/2 ÷ 9/8
Answers
Answer:
Step-by-step explanation:
What you wrote below the top line and the bottom line are not the same thing.
I think you really want the second line, but one can't be sure.
(1*2 + 5)/2 div (9/8)
7/2 // 9/8
7/2 * 8*9
7*8/18 = 56/18 = 28/9
If you really do want the top line (the latex) it is different.
1 2/5 div (8/9) Is there such a thing as tfrac? I didn't know this but there is.
(1*5 + 2)5 // (8/9)
7/5 // 8/9 Invert the bottom fraction and multiply
7/5 * 9 / 8
63 / 40
1 23/40

sorry if it's wrong
Step-by-step explanation: if you divide 255 by 11 you get 23.18181818181

Select the correct answer. The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second number? A. The equation that represents this situation is 10 − x = -18. The second number is 28. B. The equation that represents this situation is 10 + x = -18. The second number is -28. C. The equation that represents this situation is x − 10 = -18. The second number is -8. D. The equation that represents this situation is -10 + x = -18. The second number is -8.
Answers

Step-by-step explanation:
Let A is the second number
the first number is 10.
The total is -18
=> 10 + A =-18 <=> A=-18-10=-28

What is the solution of -17 = -2y + 13 – 8y?
Answers
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10

C) (f + g)(x) = -x2 + 6x + 7
D) (f + g)(x) = – x2 + 2x - 7
Answers
Answer:
A
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=4x+5\text{ and } g(x)=x^2-2x-2[/tex]
And we want to find:
[tex](f+g)(x)[/tex]
This is equivalent to:
[tex]=f(x)+g(x)[/tex]
Substitute:
[tex]=(4x+5)+(x^2-2x-2)[/tex]
Rearrange:
[tex]=(x^2)+(4x-2x)+(5-2)[/tex]
Combine like terms. Hence:
[tex](f+g)(x)=x^2+2x+3[/tex]
Our answer is A.
