f a1 = 7 and an = 5an-1 then find the value of a6

a₆ = 21875

Step-by-step explanation:

Using the recursive rule and a₁ = 7 , then

a₂ = 5a₁ = 5 × 7 = 35

a₃ - 5a₂ = 5 × 35 = 175

a₄ = 5a₃ = 5 × 175 = 875

a₅ = 5a₄ = 5 × 875 = 4375

a₆ = 5a₅ = 5 × 4375 = 21875

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
