Hey there!
To solve, let's first add 5 to both sides.
xy=k+5
Now we divide both sides by y.
x=
I hope this helps!
260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100).
here Sophia must consider 80 as 8 times 10
so that complete expression becomes
260,880 = (2 times 100,000)+(6 times 10,000)+(8 times 100)+(8 times 10)
Answer:
The solutions are (-√6,0) and (√6,0)
(-√5,-1) and (√5,-1)
Step-by-step explanation:
The equations are:

and

We make y the subject in the second equation to get;

We substitute into the first equation to get:


and 
The solutions are (-√6,0) and (√6,0)
(-√5,-1) and (√5,-1)
The best answer would be 46
Answer:
A
Step-by-step explanation:
Distribute the (-)
6x^3y^3+x^3y^3 + 5x^2y^2 - x^2y^2 - x^2y+x^2y +xy^2 +3x+3x +2-4
Cancel out bold and add:
7x^3y^3 + 4x^2y^2 +xy^2+6x-2
