Simplifying your answer
coldgirl [10]

Answer:

  -49

Step-by-step explanation:

In order to fill in the given expression, we need to know ...

  • f(-2) = -4
  • f(-3) = 5
  • f(-4) = 7
  • g(0) = -7
  • g(-3) = 3

Then the expression is ...

  √(5 -(-4)) -(-7)² +7÷(-7)·(3) = √9 -49 +7/(-7)(3)

  = 3 -49 +(-1)(3) = 3 -49 -3

  = -46 -3 = -49

Ghella [55]

Answer:

$643.50

Step-by-step explanation:

Let i be the profit realized from the sale and d be the discount made on the sale:

#John's selling price can be calculated by first adding profit, i to $450, the d to the new price as:

P_n=P_o(1+i)+d[P_o(1+i)]\\=450(1+0.3)+0.1[450(1+0.3)]\\\\\\=450\times 1.3+0.1(450\times1.3)\\\\=585+58.5\\\\=643.50

Hence, John will resell the bike at $643.50
