Every number has its purpose in this case you start at -3 then the negative sign tells you which way you are going but since we have another negative sign in between the number we go to the right instead of left with that said you put the point in number 4
For the first one I got :
V = 165/8
V = B*h
(B)11/2 * (h)15/4
= 165/8
Pls correct me if im wrong!! :)
The mapping rule for 90 degrees counterclockwise would be (-y,x). So if you had (x,y) it would transfer to (-y,x). Yours is wrong it should be (4,-3). Remember
-(-4) is 4 and -3 stays as -3.
Basically, memorize these mapping rules.
Hope this helped!
Answer:
I'm old and the way I was taught about fraction division was:
INVERT AND MULTIPLY.
SO: (5/8) divided by (1/4) equals
(5/8) multiplied by (4/1) which equals (20/8) or 2.5
