Step-by-step explanation:
The break-even point is on both curves. The y-intercept can be used for the other point in each case.
The break-even point is where cost and revenue are the same:
20/3x +50 = 10x
50 = 10/3x . . . . . . . . subtract 20/3x
15 = x . . . . . multiply by 3/10
r = c = 10(15) = 150 . . . . for x = 10
Two points you can use for graphing the lines are ...
cost: (0, 50) and (15, 150)
revenue: (0, 0) and (15, 150)
Answer:
60 x 90 = 5,400 cm^3 (cubed)
Step-by-step explanation:
Multiply them all together like, 90 x 20 x 30
7+3x-12x=3x+1
We will first make all the numbers which have x in go to the left.
So 7+3x-12x-3x, we make the 3x negative since to make it move it needs to change.
Then we will make all the sevens go to the right, so 3x-12x-3x=1-7.
So now it is much easier to figure out.
-12x=-6
Answer:
Step-by-step explanation:
Given the table
The exponential function can be written To find and substitute some values:
When then
When then
Thus,
Check remaining values:
So what we need to do is multiply 3 times 8, and then divide that by 4. So the answer is 6
