The concept that can be used in order to answer this item is that of man-days. The total number of man-days required to do the job should always be constant.
This can be illustrated by the givens above.
Scenario 1:
N1 = (4 employees)(4 days) = 16 man-days
Scenario 2:
N2 = (2 employees)(8 days) = 16 man-days
The equation for determining the value of e is equal to,
k = (d)(e)
The answer is the second choice.

To solve for a variable, you need to get it (x) by itself.
x² - 14 + 31 = 63 Add 31 to -14
x² + 17 = 63 Subtract 17 from both sides of the equation
x² = 46 Square root both sides
x =

Check your work by plugging in

for x and then

.

² - 14 + 31 = 63 Square

46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63

² - 14 + 31 = 63 Square

46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63
So,
x is
and 
.
Answer:
1/2
Step-by-step explanation:
Answer:
Slope is 5/4.
Step-by-step explanation:
The slope of two points can be expressed as
where m represents the slope,
Let (5,5) be (x1,y1) and (1,0) be (x2,y2). Thus:

You can also consider both points other way around. We can let (1,0) be (x1,y1) and (5,5) be (x2,y2) and therefore:

Therefore, the slope is 5/4.
