Step-by-step explanation:

Step 1: Define

Identify

Point A(3, 8)

Point B(-1, 1)

Step 2: Find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1 - 3)^2 + (1 - 8)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-4)^2 + (-7)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{16 + 49}$
[√Radical] Add: $\displaystyle d = \sqrt{65}$

Need help with these 4 problems

rewona [7]

Simply plug the number after the semi colon into each question's respective variable.

1. Is k=-1 a solution to this problem?
Is 9(-1)=10-(-1)?
we see that -9=10+1=11 which is not a true equality. since -9 is not 11 then "No" is the correct answer to number 1.

3.
3(-10)÷(-6)=5-(-10) ?
-30÷-6=5+10?
5=15?
No, not true, thus "No" is the correct answer.

5. 8-8=2(8)-16?
Is 0=16-16 ?
Yes!

7.
Is 2(7-2)-5(7)=5(2-7)?
2(5)-35=5(-5)?
10-35=-25
-25=-25
Bingo! Yes.
