Answer:
Step-by-step explanation:
The original price of the math book is
50$, The amount of money that you have with you is $35.
If you get a discount of 20%, it means that you get 20% of $50. This is expressed as
20/100 × 50 = 0.2 × 50 = $10
The new cost of the math book is determined by subtracting the discount from the original price. It becomes
50 - 10 = $40
Since the amount that you have with you is $35, the amount that you need to borrow in order to buy the math book is
40 - 35 =$5

Hello from MrBillDoesMath!
Answer:
x = 0, 7
Discussion:
f(g(x)) =
f ( x^2-7x) =
1/ ( x^2 - 7x)
The points NOT in the domain are those where the denominator, x^2 - 7x = 0.
x^2 - 7x = 0 => factor x from each term
x(x-7) = 0 => one or both terms must each 0
x = 0 or x =7
Thank you,
MrB
