John is 5 years older than Mary. In 10 years, twice John's age decreased by Mary's age is 35, and John's age will be twice Mary's current age. Find their ages now.
If x is Mary's age now and yis John's age now, which system of equations could not be used to solve the problem?
O y=x+ 5 and 2 y + 10) = x
O y=x+ 5 and 2 y + 10)- x + 10) = 35
O y = x + 5 and y + 10 = 2x

answer: lol haha i'm in flvs too!

but to answer question number 1 would be a.

and number 2 would be c.

c

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
