Answer:
The break- even point is attained when n=75
Step-by-step explanation:
The break-even point is defined as the point where revenue is equal to cost.
We take the equation for revenue r=15n, and set it equal to the equation c=9n+450
15n=9n+450
Subtract 9n from both sides:
6n=450
Divide both sides by 6.
6n/6=450/6
n=75
The break- even point is attained when n=75....
The general rule for a linear equation is y=mx+c where m is the slope or gradient... therefore the slope is 3.
Now we need to get 2 points on the line.
You can easily get the y-int by substituting x=0 into the equation... therefore the y-int is 11... you have one point on the line: (0,11)
Now that you have one point and we know the gradient or slope which is 3, go from the point you have found (0,11) and go up 3 and across 1 to find a second point... then simply rule a line in between the two points.
Answer:
Step-by-step Solution:
<u>Subtract or add to obtain your answer.</u>
- b + (−1.9) = −3.7
- => b - 1.9 = -3.7
- => b = -3.7 + 1.9
- => b = -1.8
Hence, the value of b is -1.8
You are told 1 cm = 45 km
The distance is 2cm
2cm / 1cm = 2
2 x 45 = 90 km
The distance is 90 km.
