Eight less than four times a number is less than 56. What are the possible values of that number?
Damm [24]

For this case we can algebraically rewrite the expression given as:

8-4x

Where:

x: Represents the unknown number

Subtracting 8 from both sides of the inequality we have:

-4x

Dividing between 4 on both sides of the inequality:

-x

We multiply by -1 on both sides taking into account that the sense of inequality changes:

x> -12

ANswer:

x> -12

Write the first four terms in the following sequences. A(n+1)=A(n)−5 for n≥1 and A(1)=9 .
luda_lava [24]

Answer:

Step-by-step explanation:

A(1) = 9

A(n+1) = A(n) - 5

n = 1 ;     A(1+1) = A(1) - 5

             A(2) =  9 - 5

             A(2) = 4

n = 2 ;     A(2+1) = A(2) - 5

             A(3) =  4 - 5

             A(3) = 1

n = 3 ;     A(3+1) = A(3) - 5

             A(4) =  1 - 5

             A(4) = -4

n = 4 ;     A(4+1) = A(4) - 5

             A(5) =  -4 - 5

             A(5) = -9

First four terms are: 9 , 4 , 1 , -4 , - 9
