Answer:
Jason originally had 87 baseball trading cards.
Step-by-step explanation:
Let the number of cards Jason originally had be, <em>x</em>.
It is provided that he bought 5 new baseball trading cards to add to his new collection.
So, the new number of cards is, <em>x </em>+ 5.
It is also provided that, his dog ate half of the cards.
Now Jason has 46 cards left.
This implies that:

Solve the above equation of <em>x</em> as follows:



Thus, Jason originally had 87 baseball trading cards.
Divide total cans by cans per case:
3408 / 24 = 142 cases per 8 hour day
40 hours / 8 = 5 days
142 * 5 = 710 cases per week
710 * 4 = 2840 cases per month
Answer:
1) 2x-5 2) -10/x^2
Step-by-step explanation:
Use power rule and constant rule for the first one:
1) f(x)=x^2-5x^1+1 (x^n)'=nx^(n-1) and (c)'=0
f'(x)=2x^1-5(1)x^0+0
f'(x)=2x-5(1) x^0=1
f'(x)=2x-5
Use just power rule for last one after a rewrite
2) f(x)=10/x
f(x)=10x^(-1) now use power rule
f'(x)=-10x^(-2) =-10/x^2
