The answer for part A: If the city is hotter in temperature more people will want the cold refreshing lemonade.
Part B: The line of best fit is a line that will have the same amount of point on each side so you should draw a straight line and then make sure it has the same amount of point on each side. To calculate the slope use Y2-Y1/X2-X1, Y-intercept is the point that intercepts the Y-intercept.
Step-by-step explanation:
Part A: Because if it is hot outside you will sweat more being less hydrated which is why more people would want a drink especially lemonade.
Remember that <span>an extraneous solution of an equation, is the solution that emerges from solving the equation but is not a valid solution.
Lets solve our equation to find out what is the extraneous solution: </span> and and <span> So, the solutions of our equation are </span> and . Lets replace each solution in our original equation to check if they are valid solutions: - For We can conclude that 7 is a valid solution of the equation.
- For We can conclude that 4 is not a valid solution of the equation; therefore, 4 is a extraneous solution.
We can conclude that the correct answer is: <span>D. the extraneous solution is x = 4</span>
