7. a. if ab = 5y - 4, bd = 7y + 3 and ad = 20y - 9, find the value of y. b. use the value of y, to find ab, bd and ad. 8. use the figure below to answer questions 8-10. point b is the midpoint of segment a c.. a a. find x if ab = 4x and bc = 2x + 10. b. use the answer for x to find the values of ab and bc. 9. a. find x if ac = 3x - 1 and bc = 12 - x. b. use the answer for x to find the value of ab. 10. a. is it possible for ab = 10, bc = 2x + 5 and ac = 5x, given that point b is the midpoint? b. why or why not?

7. y = 1, AB = 1, BD = 10 and AD = 11

8. x = 5, AB = 20 and BC = 20

9. x= 5 and AB = 33

10. No, because AC = 12.5 while AB + BC = 20 (they should equal the same and they don't.)

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
