A superintendent orders some new laptops (10) for two schools in her district. She receives a bill for $7,500. A. Draw a representation that can show the relationship between the number of laptops and the total cost.

B. Use the representation to write an equation that can be used to determine the cost of one laptop.

i dont know sorry

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
