Answer:

-1

Step-by-step explanation:

3+-4

Since the signs are opposite, we subtract the two numbers and take the sign of the larger

4-3 =1

The sign of the larger number (-4) is negative

-1

3+-4 = -1

For this case, what we must do is solve the following algebraic expression:

3 + (-4)

According to the law of signs we have to:

+ * + = +\\+ * - = -\\- * - = +

Thus, applying the aforementioned law we have to: 3 + (-4) = 3-4

Rewriting we have:

3 + (-4) = -1\\

Answer:

3 + (-4) = -1\\

How many solutions does the following equation have?
RoseWind [281]

Answer:

There will be No solution for the equation 9x - 4 = - 3x + 5 + 12x. Option B is correct.

Step-by-step explanation:

We need to determine how many solutions the equation 9x - 4 = - 3x + 5 + 12x have.

Solving the equation and finding the solutions

9x - 4 = - 3x + 5 + 12x

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

9x +3x-12x =  5 + 4

Simplifying

12x-12x =  9\\0=9

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation 9x - 4 = - 3x + 5 + 12x. Option B is correct.
