Answer:
b. -33
Step-by-step explanation:
The question is about finding the determinant of a 2×2 matrix
General formula; when given matrix A =[ b c ]
[ d e]
the determinant of A = (e×b)-(c×d)
Evaluate
(3 -3)
(-5 -6) = (-6×3) - ( -5×-3)
= (-18)- ( 15) = -33
Answer:
7x/12
Step-by-step explanation:
Let her entire allowance be represented by 'x'
She spent 5/8 of 2/3 of her allowance on magazines.
= 5/8×2/3
= 10/24
= 5/12
That 5/12 of 'x'
5/12x
Since her total allowance is x
She will be left with = x - 5/12x
x/1 - 5/12x
12x-5x/12x
= 7x/12
Hence she will be left with 7x/12
16 divided by 125 is .128
125 plus 75 is 200
.128 multiplied by 200 is 25.6 days
The answer is 18
You divide 12 buy -2/3
Answer:
See attached picture to view the graph
Step-by-step explanation:
Start by analyzing how this average idea works:
If only one member goes to the trip, it will cost him/her $1000+$200 = $1200.
If two members go to the trip, then they will share the cost as per the following: ($1000+ $200 + $200 = $1400) which they will be dividing into two people, thus costing each of them $700.
Notice that the general function that represents such average will be given by: 
Plot such function in the two dimensional plane, and you will get the asymptotic behavior shown in the attached image.
