Question 998310: If y = -2 what is the value of 16y
If x = 5 what is the value of 5x - 12
If x = 5 and y = -2 what is the value of 4x - y
If x = 5 what is the value of X2 + 5

You can put this solution on YOUR website! For the first part, if y=-2 then what is 16x? you plug in y. So 16*-2= -32. For the second part if x=5 what is 5x-12? you plug in x. So 5*5-12= 13. For the third part if x=5 and y=-2 what is 4x-y? You plug in x and t. So 4*5+12=32. On the last part I can not say with one hundred percent certainty, but I am going to list a question that I hope might help. Is X2 the same as 2x? Such as could you just insert 5*2+5? If so then your answer would be 15, if not then I am not sure how to help you, but I hope that some of this was helpful. Have a great day. Good Luck on your math work.
