A 45 gram sample of radioactive Fluorine decays to 9 grams in 8 days. How many grams of Fluorine are left in the sample after 15 days? Use the values provided below to complete and fully demonstrate your calculations by showing all steps.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

answer: 193

explanation:

200-7 = 193

im pretty sure its

(8,15)

step-by-step explanation:

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
