solve the following and explain your steps. Leave your answer in base-exponent form. (3^-2*4^-5*5^0)^-3(4^-4 over 3^3)*3^3 Pleas
Jobisdone [24]

Answer:

  3^64^{11}

Step-by-step explanation:

It appears you're trying to simplify ...

  (3^{-2}4^{-5}5^0)^{-3}\cdot\dfrac{4^{-4}}{3^3}\cdot 3^3

The final factor cancels the denominator of the fraction, so we have ...

  3^{(-2)(-3)}4^{(-5)(-3)-4}=3^64^{11}

_____

The applicable rules of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)

Hey school system is reducing the amount of dumpster loads of trash removed each week in week five there are 45 dumpster load th
natta225 [31]

Answer:

 y = -3x + 60

Step-by-step explanation:

For the answer to the question above,

 let x = number of weeks let y = amount of waste.

The linear equation may be expressed as,y = mx + b

 m and b are the slope and y - intercept, respectively. Substituting the corresponding values,

  (Week 5)                     45 = 5m + b

  (Week 10)                   30 = 10m + b

Solving for m and b gives the values as m = -3 and b = 60. Thus, the equation is 

 y = -3x + 60
