The answer is 9/v or 9 over v
-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
To add fractions, first convert them to have equal denominators.
3/4= 9/12 (multiply both sides by 3)
2/3= 8/12 (multiply both sides by 4)
From here, add the numerators while keeping the denominator.
9/12+ 8/12= 17/12
Final answer: 17/12 or 1 5/12
Rationalize the numerator:
This is continuous at 
, so we can evaluate the limit directly by substitution:
The answer for this would be 0.06.
