Can you show me the graph for y equals negative 2 times 5 to the x power

Solve: 3x+y=6 4x-2y=18 show all work !

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?

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
