Answer:
1 -2 -5
Step-by-step explanation:
5x +y = 6
5x + 3y = -4
multiply top equation by -1 and bottom by 1
-5x -y = -6
5x+3y = -4
solve and get
2y = -10
y = -10/2
y = -5
answer is -5
Start by factoring out the GCF, which is 3x:
3x(3x^2 + 2x - 1). Then factor the trinomial 3x^2 + 2x -1:
3x(3x-1)(x+1)
This is Scientific Notation right?
OK
So when the exponent over then is a negative number, that means the decimal point is jumping to the left to make the number smaller
