4)
ordered pairs : (-5,4)(-3,2)(2,6)(-3,-5) it is not a function because it repeats x’s
5)
ordered pairs : (4,5)(2,5)(1,-3)(-2,-2) it is a function because it is NOT repeating x’s
6)
(2,6)(6,8)(6,10)(8,12) it is not a function because it repeats x’s
I would think it to be A because 8/12 can be simplified into 3/4
Reduced it will be 3/4 your welcome ":)
Step-by-step explanation:
Let AB be 5cm
AC be 13cm
According to Pyathagros therom
AC²=AB²+BC²
13²=5²+BC²
169=25+BC²
BC²=169-25
BC²=144
BC=√144
BC=12cm
Area of ∆ABC=½×base×hight
=½×12×5
=½×60
=30cm²
Parimeter of ∆ABC=a+b+c
=5+12+13
=30cm
