Answer:
Answer is $15
Step-by-step explanation:
Racheal owed total=75
Total friend =5
each friend owed amount by Recheal=75/5=15
so,
Recheal owed $15 to each friend.
In the expression f(x)=23, x is not a variable. f(x) means “a function of x” or “f of x” and is in practice another way of substituting for the variable y, that is, we are saying:
y=23.
That means x is unspecified and could be anything. So on the xy plane, this is a straight horizontal line, 23 units above the x axis. That would be the best way to interpret this, although it is a little ambiguous.
Usually functions of x are expressed in terms of x, such as:
f(x) = x^2
(x-5)(x+8) is your answer!
Answer:
c = (y-0.13y)(1.08)
Step-by-step explanation:
c = cost and y = the original price
The amount of money off is 13% of y, or 0.13 of y. You would subtract that from y to get the price of the cards with the discount. For final cost, you need the cost of the cards (1) plus the cost of tax (8%, or 0.08). 1+0.08 is 1.08, so that's what you would multiply y by to get the final cost of the cards.
Hope this helped!
