You have to divide to find a common number. 143/13=11
1:11
Answer:
X=1 - y/2
Step-by-step explanation:
2x = 2 - y
divide both sides by 2
x = 1 - y/2
Answer:
(-5,2), (-5,4), and (-1,1)
Step-by-step explanation:
Let's take an example to illustrate this case:
<span>positive fraction = 2/7
</span>
<span>negative fraction = - 3/5
Now we need to subtract </span><span>- 3/5 from 2/7
Right?
2/7 - (-3/5) = 2/7 + 3/5
here we need to unify the denominators as follows:
the lowest common factor between 7 and 5 is 35
2/7 = 10/35
3/5 = 21/35
Now back to </span><span>2/7 + 3/5:
</span><span><span>2/7 + 3/5 = 10/35 + 21/35 = (10+21)/35 = 31/35
That's it
Hope that helps you</span>

Answer:
The cost function for 
is 
.
Step-by-step explanation:
The marginal cost function (
) is the derivative of the cost function (
), then, we should integrate the marginal cost function to find the resulting expression. That is:
Where:
- Fixed costs, measured in US dollars.
If we know that and 
, then:
The cost function for is .
