Check your prediction in part B by graphing the relationship. Go to your Math Tools and open the Graph. Follow these steps to create your graph: Click +DATA and type 0 in the x-column and 0 in the y-column to set the origin of your graph. Then, enter values for length and width of each TV screen in the correct cells in the table. Click PLOT to see the graph of your points. Click +RELATIONSHIP and click LINEAR. Then, check the box for Best Fit. This passes a line through the points you created. Should you make a mistake, click the X next to Data Points to start over. You should now see a graph of the points in the relationship. When you you’re satisfied with the graph, take a screen capture of it and paste it in the answer field.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
