Answer:

$1 = m$

Step-by-step explanation:

1 = 3[1] + b

$\displaystyle -2 = b \\ \\ y = x - 2$

Therefore our rate of change [slope] is authentic.

(1) let "r" denote number of rabbits, "c" number of chickens

Set up the equations:

$r + c = 1000\\4r + 2c = 3150\\\\-2r -2c = -2000\\4r + 2c = 3150\\\\2r = 1150\implies r = 575\implies c = 425$

Answer: There are 575 rabbits and 425 chickens

(2) m - number of Mike's stamps, a - number of Andrew's stamps.

Set up equations:

$m = 4a\\m-8 = 2(a+8)\\\\4a-8=2a + 16\\2a = 24\implies a = 12\implies m = 48\\$

Answer: Mike has 48 stamps. Andrew has 12 stamps.

Answer:

y=3×-11

Step-by-step explanation:

y=m+c

m=7-1÷6-4

m=6÷2

m=3

y=3+c

7=3(6)+c

7-18=c

-11=c

y=3×-11

Find an explicit formula for the geometric sequence -1,-7,-49,-343,.... Note : the first term should be d(1) . d(n) =

n200080 [17]

Answer:

Step-by-step explanation:

Given the sequence -1,-7,-49,-343,....

We are to find the nth term of the sequence

dn = ar^n-1

a is the first term = -1

r is the common ration = -7/-1 = -49/-7 = 7

n is the number of terms

Substitute

dn = -1(7)^n-1

dn = -7^n-1

hence the nth term of the sequence is dn = -7^n-1
