Answer:

x=-10/3

Step-by-step explanation:

81=27^{-x-2} \\\\81=9^2=(3^2)^2=3^4\\\\27=9*3=3^3\\\\3^4=(3^3)^{-x-2}\\\\3^4=3^{3(-x-2)}\\\\3^4=3^{-3x-6}

as you see the bases are the same so the exponents must be the same too

4=-3x-6\\\\4+6=-3x\\\\10=-3x\\\\x=\frac{-10}{3}

A business has two loans totaling $85,000. One loan has a rate of 4.5% and the other has a rate of 6%. This year, the business e
butalik [34]

Answer:

$30,000 and $55,000

Step-by-step explanation:

If 4.5% loan is x, and the 6% loan is y, then:

x + y = 85000

0.045x + 0.06y = 4650

Solve the system of equations with substitution or elimination.  Using substitution:

0.045x + 0.06(85000 − x) = 4650

0.045x + 5100 − 0.06x = 4650

450 = 0.015x

x = 30000

y = 55000

Paha777 [63]

Answer:

a₁ = 1

r = 3

Step-by-step explanation:

Since it’s a geometric series then

a₁ = 1 ( because 1 is the first term of the series)

3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.
