Well if we're talking genetics included in the answer its 3/8
(2x^2+5)(x^2-2)
The first thing would be i square roots of 5/2 and the other square root of 2
It all depends on how the equation is written.
Answer:
Coin 1: Penny
Coin 2: Penny
Coin 3: Dime
Coin 4: Quarter
------
Coin 1: 1
Coin 2: 1
Coin 3: 10
Coin 4: 25
Step-by-step explanation:
Clue 1: 1 + 1 + 10 + 25 = 37, which is an odd number so that works.
Clue 2: 1 + 10 = 11, so that works.
Clue 3: 1 = 1 < 10 < 25 (1 is equal to 1 is less than 10 is less than 25) so that works.
To solve the given matrix equation, we set up
Ax=B
where
A=[[6,-1],[-2,2]]
B=[2,16]
To solve for x, premultiply by the inverse of A
x=A^(-1)B
The inverse of A can be found as
A^(-1) = [[2,1],[2,6]]/(6*2-(-1)(-2)) [2,16]
=[[2,1],[2,6]]/10 [2,16]
=[[0.2,0.1],[0.2,0.6]] [2,16]
Verify the solution by matrix multiplication:
x=0.2*2+0.1*16=2
y=0.2*2+0.6*16=10
substitute into original equation,
6x-y=12-10=2 ok
-2x+2y=-4+20=16 ok.
It will be your duty as a student to find the right option from the answer.
