Answer:
Here's how to solve it.
Step-by-step explanation:
Ok so, a negative integer and positive ALWAYS equals a negative.
Negative and negative equals positive because it cancels out.
Positive and Positive equals positive.
So to answer your question What negative number times by a positive equals -10?
Well 5 * 2 = 10 Right?
So -5 * 2 = -10
Hope this Helps.
Answer:
1. 4 or -4
2. 2 or -2
3. 5 or -1
4. 2
5. -2
6. 1 or 2
Step-by-step explanation:
Absolute values make the answer a positive value. So in the first one to make |x|=4, x can be either 4 or -4 because the lines around x tell you to remove the negative sign. Does this make sense? So for the answers, find the values for x that make the answer the value wanted, and then find the negative of the value wanted. For example, in |5x|=10, 5(2)=10 and 5(-2)=-10. But with absolute value signs, it changes it from -10 to 10. Hope this helps, if you have any questions please let me know.

Answer:
The 1st option
Step-by-step explanation:
Because x can be anything that's not imaginary and y has to be below 2 always because of the negative value added before the 3. Also it's impossible to reverse the sign of the negative because negative x would only result in 3 becoming a fraction.
Answer:
The test results support the claim
Step-by-step explanation:
The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States was 423 eight ounce servings (Coca-Cola Company website, February 3, 2009).
Suppose you are curious whether the consumption of Coca-Cola beverages is higher in Atlanta, Georgia, the location of Coca-Cola’s corporate headquarters.
A sample of 36 individuals from the Atlanta area showed a sample mean annual consumption of 460.4 eight ounce servings with a standard deviation of s = 101.9 ounces. Using α = .05, do the sample results support the conclusion that mean annual consumption of Coca-Cola beverage products is higher in Atlanta?
Hx: u <= 423 oz
Ha: u > 423 oz (claim)
z(460.4) = (460.4-423)/[101.9/sqrt(36)] = 2.2022
p-value = P(z > 2.2022) = 0.0138
Conclusion: Since the p-value is less than 5%
reject Hx at the 5% significance level.
The test results support the claim.
