Consider equations of the form x - a= sqrt(bx+c) , where a, b, and c are all positive integers and b > 1. (a) Create an equation of this form that has 7 as a solution and an extraneous solution. Give the extraneous solution.
(b) What must be true about the value of bx+c to ensure that there is a real number solution to the equation? Explain.

Only answer if you can explain this to me correctly. Do not answer for points please.

Trent wants to buy 2 packs of trading cards for 3 dollars each. the trading card packs that trent normally buys tend to come in packs of 6, 10, 12, or 15 cards. after selecting 2 packs, trent found that the first pack of cards cost 25 cents per card, and the second pack cost 30 cents per card. trent uses this information to write the equations below in order to compare c, the number of cards in each pack.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
