Q:

write 5(1.25)^-x standard form with steps

Accepted Solution

A:
Answer:Ste4 Γ— y = 4 Γ— ( 1 4 x βˆ’ 5 ) 4 y = ( 4 Γ— 1 4 x ) βˆ’ ( 4 Γ— 5 ) 4 y = ( 4 Γ— 1 4 x ) βˆ’ 20 4 y = 1 x βˆ’ 20 Next step is to move the Β x term to the left side of the equation by subtracting Β 1 x from each side of the equation: βˆ’ 1 x + 4 y = βˆ’ 1 x + 1 x βˆ’ 20 βˆ’ 1 x + 4 y = βˆ’ 0 βˆ’ 20 βˆ’ 1 x + 4 y = βˆ’ 20 Now, to make the coefficient of Β x positive we need to multiply both sides of the equation by Β βˆ’ 1 βˆ’ 1 Γ— ( βˆ’ 1 x + 4 y ) = βˆ’ 1 Γ— βˆ’ 20 ( βˆ’ 1 Γ— βˆ’ 1 x ) + ( ( βˆ’ 1 Γ— 4 y ) = 20 1 x βˆ’ 4 y = 20 or 1 x βˆ’ 4 y = 20p-by-step explanation:
