Hi can anybody know why in xy=5 we cant just divide by x and then take the derivative ? i believe thats not how u differentiate it though​

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
