Answer:
y = 9.65x
Step-by-step explanation:
Given that total revenue is directly proportional to the number of units sold
Let the number of units sold be represented by x and the total revenue be represented by y
Given y∝x
y = kx where k is some constant
Also given that when 500 units are sold, the total revenue is $4825.
Here y=4825 and x=500
Now
k=9.65
Therefore the equation representing the relation between the total revenue and the number of units sold is
the answer is w=19-11=8
19-11=8
You just made a silly mistake. Angle A is 79, not 89. Just be more careful next time. (Remember, this figure is a cyclic quadrilateral whos opposite angles add up to 180)
y = 5x - 6
