Aclass is trying to eliminate t from the parametric equations x=t^2+3 and y=4t. beth says that she can write t= the square root of (x-3) to eliminate the parameter. why is this wrong?
a)she should have added 3 to x, not subtracted.
b)she should always solve for t as a function of y.
c)she should have taken both the positive and negative square root.
d)she should first substitute y for t before solving.
i think it might be c, but i'm not sure.

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
