1)
The opposite of -8 is 8
2)
The opposite of 19 is -19
You have to figure out how you got 26 from 2. They multiplied 13. So multiply 5 by 13. The answer is 26/65.
The answer would be (x,y) —> (x-1,y). the reasoning being that all of the points on the x axis move to the left by one unit, and all points on the y axis stay the same.
Answer:
32.1
Step-by-step explanation:
d=sqrt ((x2-x1)^2+(y2-y1)^2 )
Find length of AB
d=sqrt((2-(-4))^2+(0-5)^2)
d=sqrt(6^2+(-5)^2)
d=sqrt(36+25)
d=sqrt(61)
d= around 7.8
Find length of BC
d=sqrt((4-(-4))^2+(10-5)^2)
d=sqrt(8^2+5^2)
d=sqrt(64+25)
d=sqrt(89)
d= around 9.4
Find length CD
d=sqrt((8-4)^2+(7-10)^2)
d=sqrt(4^2+(-3)^2)
d=sqrt(16+9)
d=sqrt(25)
d=5
Find length DE
d=sqrt((4-8)^2+(5-7)^2)
d=sqrt((-4)^2+(-2)^2)
d=sqrt(16+4)
d=sqrt(20)
d= around 4.5
Find length EA
d=sqrt ((4-2)^2+(5-0)^2 )
d=sqrt(2^2+5^2)
d=sqrt(4+25)
d=sqrt(29)
d= around 5.4
P=7.8+9.4+5+4.5+5.4
P=32.1
