Increasing: (-4,-4)
Decreasing: (4,-2)
2. So for this question, you do the distributive property, which is multiplying the term outside of the parenthesis by the terms in the parenthesis. In this case, the outside term is 1/2. 8x * 1/2 = 4x and 1/2 * -16 is -8. That brings us to 4x - 8, which is our answer. Therefore, the correct answer choice is B.
3. Okay. In this problem, we are talking about the sum of 12 and a number. That's 12 + n, because sum means the answer to the addition problem D is out, because we don't do distributive property in this case. The sum of 12 + n is 4n. The expression is 12 + n = 4n. The answer is B.
Answer:
3 19/24
Step-by-step explanation:
hope it helps
7x+y-9=0
move constant to the left by adding its opposite to both sides. the sum of the two =0
Yes because 4x3^x =12^x since the coefficient is added to the answer because it is in the 3.
