Solve for x. −4≤11−3x Enter your answer as an inequality in the box.
Mamont248 [21]

Answer:

x\leq 5

Step-by-step explanation:

  • the given expression is : −4≤11−3x
  • we use following operations to solve the inequality:
  • by adding 4 on both sides, the inequality will become :

-4+4 ≤ 11-3x +4

0 ≤ 15 -3x

  • adding 3x on both sides, the inequality will become:

3x ≤ 15

  • dividing both the sides of the inequality by 3, the inequality will become:

3x/3 ≤ 15/3

x ≤ 5                  ( since, 15/3 = 5)

  • therefore the solution for x as an inequality will be x ≤ 5

If f(1)=3 and f(n)=-2f(n-1)+ 1, then f(5)=
AlladinOne [14]
Our function is f(n)=-2f(n-1)+1.
We want to find f(5).
Let's substitute 5 for n.
f(5) = -2f(5-1) + 1
f(5) = -2f(4) + 1
We need to know f(4).
f(4) = -2f(4-1) + 1
f(4) = -2f(3) + 1
We need to know f(3).
f(3) = -2f(3-1) + 1
f(3) = -2f(2) + 1
We need to know f(2).
f(2) = -2f(2-1) + 1
f(2) = -2f(1) + 1
We know that f(1) = 3
f(2) = -2(3) + 1
f(2) = -6 + 1
f(2) = -5
Now we can use f(2) = -5 to find f(3)...
f(3) = -2(-5) + 1
f(3) = 10 + 1
f(3) = 11
Now we can use f(3) = 11 to find f(4)...
f(4) = -2(11) + 1
f(4) = -22 + 1
f(4) = -21
Now we can use f(4) = -21 t find f(5)!
f(5) = -2(-21) + 1
f(5) = 42 + 1
f(5) = 43
