What is 7/8 times a variable that has to equsl to 8

answer: y = 4*0.5^x

explanation:

first we'll use the point (1,2) to isolate c in terms of 'a'

y = c*a^x

2 = c*a^1 plug in (x,y) = (1,2)

2 = c*a

c = 2/a

the use the last equation mentioned above, along with the second point (2,1) to determine the value of 'a'

y = c*a^x

y = (2/a)*a^x replace c with 2/a

y = 2*a^(-1)*a^x

y = 2a^(-1+x)

1 = 2a^(-1+2) plug in (x,y) = (2,1)

1 = 2a^1

1 = 2a

a = 1/2 = 0.5

this value of 'a' leads to

c = 2/a

c = 2/0.5

c = 4

since a = 0.5 and c = 4, the answer is y = 4*0.5^x

it can travel 372 feet in 12 seconds. ( sorry if wrong )

answer:

9 13/24

hope this

24m^2n+30mn^2+18mn

factor 6mn ( greatest common factor) out of the 3 terms:

6mn(4m) + 6mn(5n) + 6mn(3)

factor 6mn out of the first 2 terms:

6mn(4m + 5n +3)
