Answer:
The answer is 4.
Step-by-step explanation:
Given problem,
8 + (-4)
Since, in the number line the numbers left to zero are negative and right to zero are positive,
When, we move towards a negative number then we move left side while when we move towards a positive number then we move right side,
Thus, the steps involve in the given problem are follow,
Step 1 : Find 8 on the number line,
Step : we have -4, means we need to move left side 4 unit from 8,
Step 3 : the final position is 4.
Hence, 8 + (-4) = 4

y = -
Step-by-step explanation:
Given
The denominator of the expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that y cannot be, that is
4y + 2 = 0 ( subtract 2 from both sides )
4y = - 2 ( divide both sides by 4 )
y = = -
