5x + y = 27
substitute: 5x + 4x = 27
combine: 9x = 27
divide (by 9): x = 3
The definition of mean, is to add up all the numbers and divide it by how many numbers there are. So, in this case the mean would be 1+1+1+2+2+2+2+3+3+4+4+4+4+5+5+6+7+7+8+8+9 = 86. You would then take 86 and divide that by 21, and you would get 4.0
The definition of median states to find the middle of the numbers. So the median would be 4.
So you would just take 4 - 4 = 0.
0 would be correct.
6x + y = -40 is the correct answer, please brainliest if you can. Hope that helps :)
Answer:
<h3>
The y value achieves its minimum at x = 4/3</h3>
Step-by-step explanation:
Given the graph of y to be 3x² - 8x + 7, to get the value of x for which the graph function achieves its minimum y value, we need to find its turning point first.
At the turning point, dy/dx = 0
Given y = 3x² - 8x + 7


The y value achieves its minimum at x = 4/3
Answer: Option 'a' is correct.
Step-by-step explanation:
As we know that
Nominal wage is the value of wage in dollars that a particular person gets, whereas the real wage is the value of wage he is actually used that shows the purchasing power of a particular person.
If the wage is increased by 3%, and the inflation is increased by 6%.
Then, the nominal wage has increased but real wage decreased due to increase in inflation.
Hence, option 'a' is correct.
