Answer:

Step-by-step explanation:

We can use the slope formula

m = (y2-y1)/(x2-x1)

= (5-8)/(-8 - -5)

= -3/(-8+5)

= -3/-3

= 1

The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .
__________________________________________________________
Consider choice [A]: $\frac{(3)(4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [A]" .
__________________________________________________________
Consider choice [B]: $\frac{(-3)(4)}{(6)}$ ;
= $\frac{-12}{6}$ ;
= "-2" ; Yes!
→ Let us proceed with the final answer choice ;
__________________________________________________________
Consider choice [C]: $\frac{(-3)(-4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [C]" .
__________________________________________________________
The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .

7) There are 260 athletes at a meeting.<br> How many handshakes were there?

wel

Answer:

130

Step-by-step explanation:

Assuming everyone handshakes at the meeting. There will be 130 handshakes in total.

It takes 2 people to handshake, and thus to find the number of handshakes we need to do 260/2=130

130 total handshakes
