Answer:
x = 0
Step-by-step explanation:
Solve for x:
x/5 + 5 = 5
Put each term in x/5 + 5 over the common denominator 5: x/5 + 5 = x/5 + 25/5:
x/5 + 25/5 = 5
x/5 + 25/5 = (x + 25)/5:
(x + 25)/5 = 5
Multiply both sides of (x + 25)/5 = 5 by 5:
(5 (x + 25))/5 = 5×5
(5 (x + 25))/5 = 5/5×(x + 25) = x + 25:
x + 25 = 5×5
5×5 = 25:
x + 25 = 25
Subtract 25 from both sides:
x + (25 - 25) = 25 - 25
25 - 25 = 0:
x = 25 - 25
25 - 25 = 0:
Answer: x = 0
Answer:
1. A relation
2b. Continuous
Step-by-step explanation:
1: A relation is any set of ordered pairs. A function is a set of ordered pairs where there is only one value for every value.
2b: Continuous if the values belonging to the set can take on ANY value within a finite or infinite interval. A set of data is discrete if the values belonging to the set are distinct and separated.
To solve this problem, we use the formula:
z = (x – u) / s
where z is the z score value which can be obtained from
the tables, x is the sample value, u is the mean = 6.3 min, and s is the std
dev = 2.2 min
at P value = 0.90, the z = 1.28, finding for x:
x = z s + u
x = 1.28 * 2.2 + 6.3
x = 9.116
at P value = 1.0, the z = 3.49, finding for x:
x = z s + u
x = 3.49 * 2.2 + 6.3
x = 13.978 ~ 14
Therefore the longest 10% calls last about 9.1 minutes to
14 minutes
Hey there! Your answer to this problem is 2160..
Explanantion:
Since every car Sara sells, she gets 9% of the commission, this means that at the last few step, we would have to give 9% of the total cost to Sara.
If 100% is 20,000, then 50% would be 10,000. But we have to find the cost of 20%. So what we would actually be doing is multiplying 20 with 0.01. 20x0.01 is 0.2 or 0.20.
Then you add the 4,000 to the 20,000 because it states, “the next day, they sold the car 20% more than they paid. This means that you’ll have to add it. 20,000 plus 4000 would be 24,000. So 24,000 would be the cost of the car they sold.
However they didn’t wanna know the cost of the car, they wanted to know how much Sara would get. So you would have to take 9% of the cost of the cost which would be 2,160.
Final result: $2,160
The answer is (-4,-4) because y has to equal x, the first -4 is the x and the second one is the y
