10x-2-6x=2(2x-1)

Which expressions are equivalent to -6 + 3m

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
