Answer:
Step-by-step explanation:
Y=-x+8
gradient of the parallel line is the same as the gradient of the line given, which is -1
to find the y-intercept, sub the values (9,-1) into the equation we are finding which is y=-x+c
Answer;
Total profit is $18000
Step-by-step explanation:
Given in question
Number of unit is <em>1000</em>
Average revenue is <em>$100</em>
Average total cost is<em> </em><em>$80</em>
Fixed cost is <em>$2000</em>
Total revenue = average revenue
number of unit
Total revenue = $100
1000=$100000
Total input cost = total cost + fixed cost
Total cost = average cost
total unit
Total cost =$80
1000 = $80000
Total input cost = $80000 + $2000 = $82000
Profit = total revenue-total cost
Profit = $100000 - $82000 = $18000
Total profit is $18000
Basically see where it intersectst the y axis
that is where x=0
so set x=0 and solve
3(0)^2-1/2(0)+4+1
4+1
5
the y intercept is at y=5, so yo uknow that (0,5) is on the graph
