Shureka Washburn has scores of 67, 76, 68, and 99 on her algebra tests.
a. Use an inequality to find the scores she must make on the final exam to pass the c
tests.
b. Explain the meaning of the answer to part (a).
a. The solution set is x (Type an inequality.)

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
