Question

anonymous · Answer

are these inequalities or what category of math is this?

anonymous · Answer

There combine like terms in the distributive property

triciaal · Answer

are you suppose to simplify the above? what is the question?

triciaal · Answer

first distribute
multiply each term inside the parenthesis by the term outside 
then group like terms to simplify
put all the x's together, all the y's together all the numbers etc.

anonymous · Answer

simplify the combine like terms. This isn't my actual home work problem, I switched the numbers

triciaal · Answer

7(x-y) = 7*x -7*y

triciaal · Answer

group like terms eg 4 x + 7x - 8 x = 3 x

anonymous · Answer

1.	Renting a bicycle at a local Bike shop costs $40 for the first day and $10 for each additional day. 
a.	Create a chart of values and write an equation to find the total cost, C in terms of the number of days d.

triciaal · Answer

Hint   y = m x + b   m = 10 x= number of days and b = rental fee y = cost
