Ok so
8000=cost
profit-8000
then
another cost is 15rand per mug
but profit of 35 rand
35-15=20
profit of 20rand per mug
profit=R20m-R8000
where m=number of mugs sold
(R20 means 20 rand)
f(m)=R20m-R8000
break even means cost=earned
basically, when profit=0
0=R20m-R8000
add 8000 to both sides
R8000=R20m
divide both sides by 20
400=m
break even is 400 mugs
graph should be easy enough
put a point at (0,-8000) and at (400,0) then connect them
profit
f(x)=R20x-R8000
break even is 400 mugs
put points (0,-8000) and (400,0) and connect them
Answer:
m=7=2+1894+4b=4x4=16
Step-by-step explanation:
Answer:
So in exponential form
will be equivalent to 
Step-by-step explanation:
We have given the expression in radical form as 
We have to find its equivalent in exponential form
We know that if any fraction is in radical form then if we write this in exponential form then in exponential form the exponent come inverse of its number
So
can be written as 
So in exponential form
will be equivalent to 
16 books. 12 divided by six equals 2 to get the number of books per mouth. 2 times 8 to get 16.
Answer:
(2,-3)
Step-by-step explanation:
I used substitution and rearranged the second equation to y=-2x+1. Then I replaced the y in the first equation with -2x+1. So, I got 3x-5(-2x+1)=21. When you solve that you get 13x=26 or x=2. Then you replace x with 2 in either equation and end up with y=-3.
