Answer:
Then the determinant is 0.
Step-by-step explanation:
Determinant of ( 1 2 ) = 1*2 - 2*1 = 0
( 1 2 )
5.5 m
since you are finding the perimeter, you add up all the sides which equals 8.5 , since the total is 14 you subtract ,14 from 8.5 and you get 5.5. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Answer:
0.99779328
Step-by-step explanation:
The exact conversion factor is ...
1 mi = 1.609344
Then 62 miles is 62×1.609344 km = 99.779328 km.
The ratio of this to 100 km is ...
99.779328/100 = 0.99779328 . . . . ratio of 62 miles to 100 km
Answer:
a) 3x + y = -5 & b) y = 1/3 ( 21- 9x )
Step-by-step explanation:
a)
3x + y = -5
y = -3x -5
b)
y = 1/3 ( 21 - 9x)
y = -3x + 7
y = 3x + 2.5
the slop is to be same in the parallel lines. slop means m in ( y = mx + c )
so a) & b) are parallel lines. since their m is -3 .
Answer: 8/9 or .8
Advice for the future, use math w a y next time for stuff like this.
