Answer:
For as far as I know -6=a-4+b
Step-by-step explanation:
The (-4,-6) are coordinates like (X,Y) now the formula your using is y= ax+b. So the only thing you have to do is fill X and y in from the coordinates into the formula.
Answer:
First, you would need to find a common denominator for the two, in this case it would be 6 which would make the equation 3/6 + 4/6=7/6. Then in order to make the answer a mixed number you would need to divide the numerator into the demonanator, write down the whole number answer (6 will go into 7 ONE time) then write down the "leftovers". The final answer would be 1 1/6

Answer:
negative infinite, negative 72
Step-by-step explanation:
i looked it up on google
1) Cancel out the common factor which in this case is 8 
2)First apply exponent rule
now cancel out the common factors which are n and n+7 leaving you with 
3)Factorize
cancel out the common factor in this case x+2 leaving you with 
4) Factorize
cancel out the common factor in this case 3w-1 leaving you with
